Starwave 70 ED Triplet APO Travel Refractor

Ask a question about this product
The Starwave 70 EDT-R refractor has a triplet ED lens system with premium Japanese Ohara SFPL-53 ED glass element. Super-high transmission coating (STM Coating) is used on all air-to-glass surfaces for high contrast.

The tube is made from light weight aluminium alloy with CNC machined components. A tough matte pearl powder coated tube and hard-anodised fittings give durability and great looks.

The Starwave 70EDT-R can be used for both visual observing and astro-photography at F4.8 with the optional 0.8x Planostar V2 focal reducer.

Visual observing with the Starwave 70ED-R: Detail is easily visible on the larger planets such as Jupiter, with both the four principle moons and main cloud belts easily visible at high power. Saturn's rings and thousands of lunar craters, as well as volcanic plains and mountain ranges are all easily visible. Add a high quality Kendrick solar filter or Daystar Quark Hydrogen Alpha solar eyepiece and you have the perfect 70mm solar observing system. The 420mm focal length is ideal for the Daystar Quark, allowing you to capture the entire disc of the sun at low power, enabling viewing of solar prominences and their development over a few hours. The 70 EDT-R will easliy reveal detail and structure within sunspots with white light solar filters. Viewing bright extended deepsky objects or star-clouds with a low power eyepiece is very rewarding too, with the inherent contrast of a high quality refractor giving objects that visual "pop" against a dark background - something not possible with reflecting telescopes.

Ergonomics: The light weight dual speed 2" Rack and Pinion Geared focuser gives a good balance between lifting power and stability for large eyepieces or cameras. Fine tilt-adustments can be made using the focuser, so you can adjust the optical tube to produce very round stars at this fast F6 focal ratio. The focuser has a 2" rear accessory port with a zero-flex 3 thumbscrew compression ring and a 2"-1.25" adapter with compression ring and dust plug.

Finder scopes: The optional Starwave 50mm or 60mm RACI (Right angle Correct Image) finder-scope or the Starwave RDF (Red Dot Finder) both have a quick release bracket which fits the focuser and is left on, so you can keep it aligned for quick setup. What's more you can use the Starwave 50mm Guide Scope for long exposures imaging with an equatorial mount.

Grab 'n go portability: The Starwave 70 EDT-R is a great "grab 'n go" portable telescope-kit for visual observing or astro-photography. The telescope is about the same size as a telephoto camera lens, so it will easily fit in your camera bag.

Photography with the Planostar v2 0.8x Reducer Flattener:
CCD cameras: The backfocus distance from the flattener flat shoulder is 65.82mm (see diagram) excluding threads. The rear thread is T-Thread male or M42x0.75 so you will need appropriate spacers.
DSLR cameras: You can order the Planostar v2 Reducer Flattener with DSLR adapter and spacer for either Nikon F-mount (46.5mm spacing), or Canon EOS-mount (44mm spacing). These are pre-set to give the correct spacing for your DSLR. A filter can be screwed into the front of the reducer.

Mounting the Starwave 70 EDT-R on a camera tripod: Attaching the telescope to a photo or video tripod mount takes seconds by means of the 1/4" photo thread on the dovetail-base. A photo-tripod is perfect for grab and go visual astronomy, digi-scoping and use as a terrestrial spotting scope with superior astro-eyepieces. Astro telescopes usually have higher quality optics than spotting scopes, however they display a reversed, upside down image, which is perfectly acceptable for night-time viewing but not for daytime use. To use your 70 EDT-R as a spotting scope, simply plug in the Altair Lightwave 45 degree erect image prism diagonal and add an eyepiece. which produces an upright, correctly orientated image. Needless to say there are few if any spotting scopes which compare to a triplet refractor with FPL-53 ED glass element when it comes to colour correction and sharpness at high powers.

Mounting the Starwave 70 EDT-R to an astro-mount: Most GOTO mounts which support "Vixen/Synta-format " dovetails such as the iOptron SkyGuider, Skytracker, Cube PRO, Minitower range, SmartEQ PRO, Skywatcher EQ5, and so-on will fit directly. The mounting base can be detached and re-mounted facing backwards to change the balance point for smaller loads. A "Vixen-format" or "Losmandy-format" dovetail bar can be used to attach this telescope to any mount. Many choices are available within the Altair TMS Telescope Mounting System or Starwave Mounting System. Product codes: VDB-CL-180 or SW-MINI-VBAR-200 are probably the best choices. They are attached by means of the standard photo tripod threads in the mounting base. Longer dovetail bars, for example the Altair TMS 250mm Dovetail Bar (code: VDB-250) can be used to gain more length for balancing with heavier accessories, such as cameras and filter wheels. Visual observers might choose longer dovetail bars for balancing with bino-viewers or heavy eyepieces. The mounting base can also be completely detached, allowing the Starwave 70 EDT-R optical tube to fit guide scope rings, such as the Altair TMS Lightweight Rings.

**Please Note** The Case is included without charge and is designed to protect the telescope in transit. In the event the case arrives with any cosmetic damage it will not be replaced or exchanged.

Altair Starwave 152 V2 "Red Tube" Achromat Refractor Telescope

The Starwave 152mm V2 delivers rich field views of the night sky using a large 6 inch / 152mm of unobstructed aperture at an incredible price. What's more, this lens isn't your average achromat lens. It is constructed from high quality Japanese Ohara and German Schott glass with top quality coatings, a very smooth polish and accurate surface figure free from striae.

A unit was sent (with a smaller 2" focuser) to astronomy writer Ade Ashford, who has written a comprehensive - Click here for review

NOTE: The review telescope was the older version with 2.0" Crayford focuser. The newer Starwave Red Tube 152 Achromat ships with the larger 3.0" focuser and improved optics.

Another use for the Starwave 152mm Achromat is solar imaging. If you ever wanted to push your Daystar Quark or Quantum to the next level this optical tube has it all. 6" of aperture and a fast focal ratio for the fastest frame rates. Check out solar imager Gary Palmer's amazing solar shots with Altair GPCAM Mono, Daystar Quark and Starwave 152mm Achromat to see what can be achieved.

For rich field viewing of deep sky objects such as comets, clusters and nebulae, the Starwave 152 offers a higher contrast view equivalent to an 8" Newtonian reflector, with similar perceived light grasp, but without the maintenance overhead and need for regular collimation. It also sports higher contrast due to the lack of central obstruction which makes deepsky objects appear to "pop" out from the background for very pleasing views. By using a Contrast Booster filter to remove any residual chromatic aberration, the Starwave 152 F5.9 can also be used for high powered observation of the moon and planets. This often isn't possible with cheap mass-produced achromatic optics of similar focal length. It should be noted that chromatic aberration of this telescope is very low considering the fast focal ratio of the lens system, and that the lens design has been optimised for the yellow/green wavelengths to which the human eye is most sensitive. Therefore visual performance is better than the traditional Frauhofer achromat designs employed in cheaper achromats, and as reviewer Ade Ashford comments, the Starwave 152 Achromat outperforms typical F8 Achromats of the same aperture.

The inside of the optical tube has several baffles, and the multilayer lens coatings are extremely efficient to further improve image contrast. Surface polish is imrpoved to reduce scatter, which is very low for such a large aperture refractor lens. All these factors make the Starwave 152mm a high contrast telescope for achromat lovers who want a short, portable portable optical tube, but with with "big glass" 6" aperture.

At only 760mm length when the dewshield is folded back, the Starwave 152 one of the most portable 6" aperture refractors on the market today. It will put less strain on your mount too, because the 11.2kg weight is distributed along a shorter length than other larger refractors, so torque / moment-arm effects are minimised.

Altair Starwave 80 ED Refractor

NEW 2015 Version

The Starwave 80 ED refractor's ED optics produce a high contrast image with very good colour correction, and the over-engineered optical tube is strong and rigid enough for long exposure astro imaging.

The oversize, tension-adjustable 3.0" Crayford focuser can handle heavy loads like a large eyepiece or DSLR easily. The ED Doublet design offers good colour correction while keeping the optical tube compact enough for transport. The 80ED lens is well regarded for visual observing. Optical smoothness, figuring and low temperature performance is very consistent, and the field is flat enough not to be distracting with wide field eyepieces - with most eyepieces function very well at the F7 focal length.

As with most refractors, a high contrast image is delivered at the eyepiece because there is no central obstruction like mirror telescope designs.

When it comes to astro imaging, the Starwave 80ED optical design has become an ideal choice for customers wanting a cost effective dual imaging and visual capable telescope all in one unit, offering better colour correction than an achromat telescope with same or even longer focal length. The over-engineered 3" rotating dual speed focuser can handle heavy loads, with a direct threaded connection to the optional dedicated Starwave 0.8x reducer.

Tube rings have the standard M6 hole pattern to fit most hardware mounting systems on the market. A Vixen-style dovetail bar and case are included.

You will need a mount, eyepieces and a star-diagonal to use this high quality telescope.

A finder scope or RDF (Red Dot Finder) isn't strictly necessary at this short focal length if you find the object with a low power eyepiece and increase the power from there onwards. Most finder scopes will fit the Starwave 80ED focuser directly., and we recommend the Starwave 50mm Deluxe Finder Scopes, which are a perfect fit, and can be used for an auto-guider when imaging.

The aluminium tube achieves thermal equilibrium very quickly, and the metal construction conducts heat easily to the front optics (essential for imaging). The over-engineered 3" rotating dual speed focuser can handle heavy loads, with a direct threaded connection to the optional dedicated Starwave 0.8x reducer (reducer option available in dropdown menu below). Tube rings have the standard M6 hole pattern to fit most hardware mounting systems on the market. A Vixen-style dovetail bar is included.

Included:
- 80mm F7 ED Doublet optical tube (555mm focal length).
- Oversize Dual Speed 1:10 ratio 3.0" Crayford Focuser, 360° rotation, with stainless steel rail and tension adjustment (ideal for imaging).
- Crayford focuser rear assembly can be remove for direct threaded attachment to the optional Planostar 0.8x reducer (for imaging).
- Retractable dew shield.
- 2" to 1.25" eyepiece adapter with brass compression rings.
- 2x Tube rings with standard M6 30mm hole pattern (enabling the telescope to be balanced more easily for imaging, or dual-mounted as a guide scope).
- Standard "Vixen-format" dovetail bar.
- Transport case.

The Included case is supplied free of charge. It is designed to protect the scope when we send them out by courier. In the unlikely event the case arrives with any marks or dents it will not be replaced.

Altair Starwave 102ED Refractor Telescope with 3" Crayford Focuser

The Starwave TM 102 ED refractor sports hand crafted ED optics producing a well colour-corrected image at 715mm focal length. It is the ideal refractor for those who want to enjoy visual observing and astrophotgraphy in one capable unit.

Visual observing: The solar system objects are not only all within easy reach of this 102mm optical system, but will display good detail when viewed through the Starwave TM 102 ED optics. Cloud belts on Jupiter are easily visible, as are thousands of craters on the Moon, and even the Cassini division in the rings of Saturn can be seen as a thin dark line. Brighter deep sky objects such as the Orion Nebula, Andromeda Galaxy, Ring Nebula and Hercules globular cluster are all well within reach of this 102mm optical system.

Imaging: With the optional Altair PlanoStar 2" 0.8x Reducer / Flattener for Starwave 102ED & 110ED refractors , the focal ratio changes from F7 to F5.6, resulting in shorter exposure times, and a larger field of view. The 3" focuser visual back can be removed, allowing a direct threaded connection between focuser and reducer to eliminate any flex for sharper images.

For imaging with a DSLR, choose the Planostar 0.8x reducer with M48 DSLR adapter:.

The over-engineered 3.0" rotating dual speed Crayford focuser can handle extra-heavy loads, and features a non-slip stainless steel bearing plate with full tension adjustment. The aluminium alloy optical tube achieves thermal equilibrium quickly, minimising the formation of tube currents and permitting efficient use of dew control equipment.

Tube rings are provided with standard hole patterns to fit most hardware mounting systems on the market, and are fully compatible with Starwave TM dovetail plates and clamps.

The Included case is supplied free of charge. It is designed to protect the scope when we send them out by courier. In the unlikely event the case arrives with any marks or dents it will not be replaced.

Altair Starwave 110ED Refractor Telescope with 3" Crayford Focuser

The Starwave 110 ED delivers slightly higher resolution and more light grasp than the 102mm ED for a small increase in weight and size. Deep sky and planetary images show slightly increased brightness and image scale, letting you discern slightly more subtle details at the eyepiece. Colour correction is better in the red Hydrogen Alpha regions of the spectrum than in the blue regions, and this is a great galaxy-imaging scope. We classify this telescope as a "Semi-APO" and it significantly outperforms an achromat refractor of equivalent focal length at an incredible price. With a Contrast Booster filter to remove any residual chromatic aberration at very high powers, it will compare to an APO costing several times the price on the moon and planets.

The additional aperture of the 110mm ED design makes this a suitable option for those who want slightly more performance over a 4" refractor, but who still want a relatively portable telescope which won't over-tax their mount.

The Starwave 110ED is still quite portable for field use. The focuser features the same robust design as the ED102 version, and an optional dedicated 0.8x reducer/flattener as well as the slightly larger aperture, give this telescope improved field performance over a larger area, making astro imaging with larger CCD chips and DSLR camera even easier. When using the flattener, the focal ratio changes from F7 to F5.6 (choose the flattener option in the drop-down menu below).

The Included case is supplied free of charge. It is designed to protect the scope when we send them out by courier. In the unlikely event the case arrives with any marks or dents it will not be replaced.

Altair Starwave Classic 102mm F11 Achromat Refractor Telescope with 2" Crayford Focuser

Please note - we include this telescope not because it is suitable for deep sky imaging (It isn't) but because it is the closest thing commonly available to a traditional long focus achromatic refractor.

As a big fan of the older design of long focus achromats and owning a whole variety of them myself, including one of these, I know well how good the image sharpness and contrast is in these traditional old instruments and how pleasingly sharp the images are. In todays world of fast short focus refractors many observors have never experienced the wonderful views through a traditional long focus achromat.

Please note that the commonly available faster F Ratio achromats give nothing like the quality of view and image sharpness.

The Starwave 102 F11 is a throw back to the huge numbers of high quality achromats that were produced up the the late 1980's and will give you a view of Jupiter or the Moon for example that is very comparable in sharpness, definition and contrast to more expensive ED APO type of refractors.

Optical charateristics: The Starwave TM Classic 4" F11 Achromat refractor sports hand figured optics at a long F11 focal ratio made from top quality Japanese Ohara glass, free from striae and internal stresses. This leads to a lens which holds it's own at high powers where others fall away. Four inches of aperture gives about 62% more light grasp than an 80mm refractor. The optics are optimised in green light which is the wavelength most visible to the human eye. This, and the long focal length of 1120mm provides a much better level of colour correction and therefore contrast than short focal ratio achromat refractors. A minus violet filter removes residual chromatic aberration on very bright objects at high powers like Venus for example. Field curvature (a feature of all refractors) is for all intents and purposes invisible at this focal ratio, and therefore deep-sky observing is a treat. (Try Altair KITAKARU RPL Orthoscopic Eyepieces!). Planetary images are crisp and sharp with relatively high magnification afforded by the long focal length, which means you can use larger long eye relief eyepieces too. Solar observing with a filter is also very rewarding at this unobstructed focal length, as is eyepiece projection. Finally cool-down is quick with little change in lens characteristics as temperature changes, making this an ideal telescope to keep in the lounge of conservatory, ready for a quick observing session. The Starwave Classic looks the part of a classical refractor too, and is a real talking point in any lounge or on any balcony.

Optical tube assembly: The CNC machined tube construction and lens quality is better than the cheap achromats flooding the market these days. Tough glossy automative grade paint on the tube is easy to clean and very tough. The internally baffled aluminium tube achieves thermal equilibrium quickly, minimising the formation of tube currents, and permits the use of Kendrick Dew Control System heaters to easily transfer heat to the optics. The 2" rotating Dual-Speed Crayford focuser has a smooth action, with a tension-adjuster on the underside. A 250mm Vixen/Synta-format dovetail bar is supplied together with CNC machined tube rings. A finder mounting bracket is included, mounted on the focuser, compatible with most finder scopes including the Altair 60mm Deluxe Finder Scope.

Altair Lightwave 72mm F6 ED APO Refractor

The Lightwave 72/432 ED-R refractor delivers very good colour correction, delivering the high contrast images refractor owners appreciate. The ED doublet lens system features an ED element made from premium Japanese Ohara glass. The elements have been figured with excellent smoothness and very effective super-high transmission coating (STM Coating) on all air-to-glass surfaces for exceptional contrast.

In fact, the colour rendition is so good for the price, that telescopes previously employing this same lens have been described as apochromats or "APO" by both manufacturers and their customers.*

Versatility: The Lightwave 72 ED-R is a very versatile telescope, performing very well at both visual observing and astro-photography. Detail is visible on the larger planets such as Jupiter, with both the four principle moons and main cloud belts easily visible at high power. Saturn's rings are striking, and the Cassini Division in Saturn's rings is easy to see. The Moon will reveal an hundres of craters, as well as volcanic plains and mountain ranges, particularly enjoyable when the light strikes the moon at an angle during the 3/4 lunar phase. Adding a high quality Kendrick solar filter or Daystar Quark Hydrogen Alpha solar viewing eyepiece would give you a powerful solar observing system. In fact the Lightwave 70 ED-R with it's F6 focal ratio and 432mm focal length is ideal for the Daystar Quark, allowing you to capture the entire disc of the sun at low power, enabling viewing of solar prominences and their development over a few hours. The 72 ED-R will easliy reveal structure in sunspots with a white light or Hydrogen Alpha eyepiece such as the Daystar Quark.

The dual speed "Linear Power" Rack and Pinion Geared focuser has eight adjustable internal roller bearings, so you get more "lifting power" and stability for large eyepieces or cameras. Fine tilt-adusments can be made using the focuser, allowing astro-photographers the ability to fine-adjust the optical tube to produce very round stars at this fast F6 focal ratio. The focuser can be rotated to frame celestial objects the way you want them. The focuser has a 2" rear accessory port with brass compression ring and a 2"-1.25" adapter with brass compression ring and dust plug. The optional Lightwave 50mm RACI (Right angle Correct Image) finder-scope or the Lightwave RDF (Red Dot Finder) both have a quick release bracket which fits on either side of the focuser unit. Once the quick release bracket is installed, you can leave it on, so adding the finder takes seconds.

Grab 'n go portability: The Lightwave 72 ED-R comes in a tough hard skinned aluminium flight-case with a foam insert, and pre-cut removable inserts for an eyepiece, a diagonal and Red Dot Finder, making it the ideal "grab 'n go" portable telescope-kit for visual observing or astro-photography. The case will easily fit in an aeroplane overhead locker, so you can travel with your telescope along as cabin-luggage. The case measures 39x25x19cm and is lockable with 2x keys included.

Mounting the Lightwave 72 ED-R on a camera tripod: Attaching the telescope to a photo or video tripod mount takes mere seconds by means of the 1/4" photo thread on the dovetail-base. A photo-tripod is perfect for grab and go visual astronomy, digi-scoping and use as a terrestrial spotting scope with superior astro-eyepieces. Astro telescopes usually have higher quality optics than spotting scopes costing many times the price, which is necessary for higher power magnification demanded by astronomers. They do however display a reversed, upside down image, which is perfectly acceptable for night-time viewing. For daytime use, simple plug in the Lightwave 45 degree erect image prism diagonal, which produces an upright, correctly orientated image. It's also compatible with astro eyepieces, so you can take advantage of these lower priced yet higher quality optics).

Mounting the Lightwave 72 ED-R to an astro-mount: Most GOTO mounts which support "Vixen/Synta-format " dovetails such as the iOptron SkyGuider, Skytracker, Cube PRO, Minitower range, SmartEQ PRO, Skywatcher EQ5, and so-on will fit directly. The mounting base can be detached and re-mounted facing backwards to change the balance point for smaller loads. The mounting base is slightly wider than the 44.5mm Altair TMS Mini-Vixen-format clamp required for the Sabre mount, so a correct size dovetail bar is required to use this telescope with the Altair TMS Telescope Mounting System. Product codes: VDB-CL-180 or SW-MINI-VBAR-200 are both compatible. They are attached by means of the standard photo tripod threads in the mounting base. Longer dovetail bars can be used to gain more length for balancing with heavier accessories, such as cameras and filter wheels. Visual observers might choose longer dovetail bars for balancing with bino-viewers or heavy eyepieces. The mounting base can also be completely detached, allowing the Lightwave 72 ED-R optical tube to fit guide scope rings, such as the Altair TMS Lightweight Rings (code: GSR-100), or the Starwave 110mm guide scope rings (Code: SWGSR-110). Both systems have many options for mounting piggyback, or side-by-side.

Beginner? Why not start out with quality equipment? This is a great scope to get you and your friends familiar with the night-sky, or started in astro-photography. Unlike most starter-telescope, optical and mechanical quality are very good. Altair's philosophy is not to start with low quality equipment, but to include high quality accessories an optics in a beginner telescope. The Starwave 70 ED is an ideal beginner's choice for wide-field imaging with your DSLR or compact camera. The Starwave 70 ED is a lot easier to use than a Newtonian reflector, due to it's small size and light weight, and because the optics do not require frequent collimation or adjustment. For visual observing, you don't even need an astronomical mount right away - the Starwave 70ED will fit a camera tripod to get you started with wide field observation of the night sky.
The advantage of ED optics for Astronomical visual observation: When compared to small Achromatic refractors of similar size, length and focal ratio, the Starwave 70 ED offers better mechanics for easier focusing, and truer colour rendition due to the ED optics. The Starwave 70 ED delivers a nd delivers a sharp "contrasty" image with good colour correction and tight star images. The 70mm aperture gathers about 100 times more light than the human eye, and in a dark-sky location, observation of star clouds and larger more extended objects is most enjoyable. With a higher power eyepiece or Barlow lens, this telescope will show plenty of detail on the moon, and it will show the planetary disc of Jupiter, with the major cloud bands visible as stripes across the disc, as well as the four largest Galilean moons and their movements from hour-to-hour. Saturns rings are visible as distinct from the planet at high powers.

Daytime terrestrial viewing: By adding an optional image-erecting prism diagonal, the Starwave 70 ED becomes a real performer when it comes to terrestrial and nautical observation, offering performance in the same category as ED spotting scopes costing many times the price. Simply increase the brightness on the Red Dot Finder and you can use the scope with pinpoint accuracy during daytime.

Mount choices: Due to it's compact size, this is an ideal telescope to use with the iOptron Cube or Smart EQ GOTO mounts, or the Altair Astro Sabre AZ series mounts. However you don't have to buy an astronomical mount right off to enjoy the heavens, because the Starwave 70 ED fits directly to a standard photo tripod, having two Standard 1/4 thread photo tripod holes underneath the dovetail base.

Travel friendly: A tough, high quality flight case is included, falling well within any known cabin luggage size restrictions (at 28x39x15cm) to protect your scope on it's travels. The case has enough space inside for a some eyepieces, a diagonal and a finder.

Astro imaging or terrestrial photography with the Starwave 70ED: A smooth and rotatable dual speed "non-slip" 2" Crayford focuser is supplied, with tension adjustment, able to carry a basic light weight DSLR or a light weight CCD camera. The focuser sports a steel guide-plate which eliminates slippage and increases the focuser's carrying capacity to about 2.5KG, which is more than enough for a DSLR or CCD camera and filter-wheel. The ED Doublet lens system features a special ED glass element, which results in less colour aberrations in the image. The optics are compatible with the Lightwave field flattener and reducer range, in particular the Lightwave 1.0x Field Flattener. The rear 2" visual back can be removed from the focuser, revealing a female M54x0.75x threaded accessory port. Various adapters are available to attach your particular camera system via this method. The machined aluminium tube transmits heat to the optics, which benefits users of dew control systems.

Finder scopes and auto-guiding: The RDF or Red Dot Finder can be attached using a separate finder stalk and Universal Finder Bracket. The Altair 60mm Deluxe Finder Scope / Miniguider system attaches to the focuser directly using the Universal Finder Bracket, enabling auto-guiding and easy guide-star selection, in a compact light weight package.

Feature summary:

The light yet tough optical tube folds down to 30cm in length and weighs about 2kg, sporting a retractable dew shield.
ED optics offer improved colour correction, which produces a higher contrast image, whilst allowing a short, portable telescope tube.
The eyepiece, diagonal and RDF finder accessory package is of high quality, justifying the high quality optical tube.
The dual speed rotatable focuser has a steel bearing plate on the base, and is easily able to carry a DSLR or medium size CCD camera without slipping when the focuser tension is adjusted to suit. Fine focus is easy to achieve with the dual speed 1:10 ratio thumbwheel.
A compact and tough foam-filled transport case is supplied with space for accessories.
The SW70ED telescope can be mounted on a photo tripod with standard 1/4" thread and for attachment to other scopes or imaging systems, it can be attached to a longer dovetail bar with two commonly available 1/4" tripod thread screws.
