Altair Starwave 70ED Refractor Package

Featuring ED optics, the travel-friendly Starwave 70mm F6 ED Doublet refractor can be taken anywhere.

The optical tube folds down to just under 30cm length with the dewshield retracted, and weighs about 2kg.

The Starwave 70ED is capable of both visual observation and wide-field imaging in a single telescope.

Furthermore the included accessories are high quality items, designed to do the Starwave 70 ED optics justice.

The new 2014 version includes the following high quality accessories:
Starwave 70mm F6 ED Doublet optical tube with 2" Dual Speed Crayford focuserRDF finder multi reticule, variable brightness with metal body and mounting stalk.
1.25" Dielectric Diagonal 99% reflective.
Wide field 17mm Eyepiece with 65° APOV, 16mm Eye Relief, 1.25" barrel and dust caps giving 25x magnification.
Carry Case ** see Below**

2"-1.25" Push-Fit Adapter.
Front and rear dust caps.
Metal dovetail base with standard 1/4-20" threaded "photo tripod format" holes, so you can use the scope with a camera tripod.
Also fits the iOptron Smart EQ PRO and other mounts.
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.

Altair Astro Wave 130 F7 ED Triplet APO

The Altair Astro 130mm F7 ED Triplet APO refractor uses a 915mm focal length lens cell with Japanese FPL51 ED glass from Ohara which is cpecifically chosen to be free of internal stresses and striae which affect optical quality in large size refractors.

This telescope is not like other telescopes using the similar or the same mechanics and has rapidily gained a reputation for performance above the norm especially with visual observers. This is due to a special modification process at the final stages of production, cluminating in the production of a laser interferogram image which is delivered with every telescope.

NEW 2014 Version with a light weight dual speed "Rack 'n Pinion" focuser, Teflon-tipped adjustable rotator, CNC machined internal knife edge baffles, and a self centering 2" adapter. Field flatteners can be attached directly as usual by unscrewing the self centering rear assembly.

What makes the Wave Series different from other refractors of similar specification? Every single Wave Series scope has been tested individually and signed off on it's optical quality before shipping. A test report is provided with each scope and each scope as a serial number engraved on the lens cell corresponding to that test report. This teting is done by an optical lab employed by Altair, and the results are nothing short of spectacular, as witnessed by customers. Altair usually takes the top 10% of any glass production run from their suppliers, then tests each scope a second time before the lens cell is assembled and collimated with serial number engraved on the lens cell, and we pay extra for this service. That is why we are confident enough to provide an optical test report with each Wave Series telescope. Altair call this "grade 4 optics". Altair never source sub-standard or rejected optics, and any optics which do not meet criteria are sent back to the supplier without a serial number. Altair always purchase the highest grade of glass available for each production run, to differentiate their product in the market. What's more, Altair guarantees your Wave Series telescope will arrive in perfect collimation, and will always ship them using a fully insured professional courier service, so your telescope is guaranteed to arrive ready for you to enjoy.

A rigid aluminium tube gives the correct thermal properties for any large airspaced triplet refractor, allowing the use of Kendrick dew control heaters to conduct heat to the optics, and quick thermal equalisation and relative freedom from tube currents, unlike carbon fibre or non-metal composite materials which are not only brittle but often hinder thermal equalization because they do not conduct heat. Two two heavy duty tube rings gives a stable mounting platform for astro photography, and a large dewshield delays the onset of dew and keeps dust and pollen away from the objective.

The objective cell can easily be adjusted in tilt by the customer, by accessing the front push-pull tilt adjustment screws when the dewshield is unscrewed (see thumbnail pictures).

This new production run includes our new Rack and Pinion geared dual speed focuser with self centering 2" collet adapter and machined internal baffling system. This, and an inevitable increase in the price of the 3rd tier optical modification and QC service we employ for all Wave Series telescopes, has increased the product price over the previous production run. The price and specification of this product is subject to change without notice.

The new Rack and Pinion dual speed focuser has a smooth teflon loned rotation system and a self-centering 2" pushfit end-cap. The end cap can be removed to attach the PlanoStar TM 3" 1.0x Flattener and the Planostar TM 3" 0.79x reducer by means of a threaded adapter. (Options available in the dropdown menu when ordering).

Two heavy duty tube rings are provided with standard hole patterns to fit most hardware mounting systems on the market.

Altair Wave Series 80mm F6 ED Triplet APO - Now Includes INterferogram as Standard

he Altair Astro 80mm ED Triplet APO refractor uses a 480mm focal length lens cell with Japanese FPL53 ED glass from Ohara. A rigid aluminium tube with two tube rings allows stable mounting for astro photography, and the rotating dual speed focuser can handle heavy loads, with a direct threaded connection to the optional dedicated Altair 1.0x M48 field flattener (available separately).

What's included?
Altair 80mm Super ED Triplet telescope optical tube with serial number engraved on the lens
Optical test report corresponding to the serial number
Telescope tube rings
Vixen-format 1.75" dovetail bar
New CNC machined dual speed "Rack 'n Pinion" focuser with self-centering 2" pushfit adapter and Teflon tipped rotator
2" to 1.25" Self centering adapter
Front metal objective cap
1.25" plastic rear insert cap
a "free" foam filled transport case

EW 2014 Version includes a lighter weight OTA and a light weight dual-speed "Rack 'n Pinion" focuser, Teflon-tipped adjustable rotator, CNC machined internal knife edge baffles, and a self centering 2" rear adapter, and even a 2" to 1.25" self centering adapter with brass compression ring (sold by some companies for £50 on it's own!). Optional Field flatteners can be attached directly by unscrewing the self centering rear assembly and removing it from the focuser.

Tube rings are provided with standard M6 hole patterns to fit most hardware mounting systems on the market, and are fully compatible with the Altair TMS Telescope Mounting System TM.

We recommend the Altair Astro 60mm Deluxe Finder Scope which is a perfect fit and can double as an autoguider for imaging by adding the Altair Miniguider adapter.

Altair Wave Series optics: Your 80-480 Super ED Triplet APO optics are repeatedly tested and re-figured at the final stages of production, until signed off by the optician in charge of the production batch. The best quality Ohara SFPL-53 glass is used in the ED element, which is fully annealed and cooled over several days to relieve internal stresses, having an Abbe number of 94.94, plus or minus .01 per batch. SFPL-53 is referred to as Synthetic Fluorite or Super ED. (Fluorite crystal by comparison is 94.99 but with slightly more variation from batch-to-batch, and has less stable chemical, thermal and physical properties). Each lens cell has a serial number engraved on the front ring. Working closely with our optical technicians, we have introduced a second and unique quality assurance process for all Wave Series lenses, to ensure the highest quality and lowest chromatic aberration. These lenses are modified, and are far superior to the "normal" production quality lenses offered by most manufacturers. Star tests speak for themselves, and colour correction is superb, as can be seen from the various observing reports and images taken with Wave Series refractors. Blue stars show negligible bloat in long exposure images. During the production process, a laser interferometer image is acquired in 532nm green light, and imported into fringe analysis software to create an optical test report. Each image is a "snapshot in time" of the lens on the test bench. Vibration, air currents and other environmental factors can influence the image and the outcome of the report slightly, though are minimised during testing. Providing a test report is a useful way for us to assure that our our internal production quality is consistent from batch-to-batch. A paper report printout is included with your telescope, which corresponds to the serial number visible on the lens (an example report is shown in the thumbnail images below the main product image, with serial number deleted).

The Altair 102-715 EDT is the ideal multi-purpose telescope platform, suited for the amateur astronomer interested in both visual and imaging use, and offering excellent performance in both areas. It offers a wide-field or a high power view, and is therefore more than a reflector, enabling high contrast views of both planets and wide field deep sky objects.

and crafted optics: Your 102-715 Super ED Triplet APO optics are hand figured at the final stages of production and repeatedly tested until signed off by the optician in charge. The best quality Ohara SFPL-53 glass is used in the ED element, which has an Abbe number of 94.94 plus or minus .01 per batch. SFPL-53 is referred to as Synthetic Fluorite or Super ED.

These lenses are extensively modified, and perform far in excess of normal production quality lenses. Star tests speak for themselves, and colour correction on images is the best in it's class, as can be seen from the various images taken with the Wave Series refractors - with blue stars in particular. A laser interferometer image in 532nm green light is included with your telescope. This is the final test image created once the optician has completed your unique objective, and stands as a certificate of quality attained by Altair Astro's unique second-tier production process.

Optional Altair PLANOSTAR 3" Field flattener for astro-imaging: A optional, dedicated large format field flattener is available separately with this telescope package for use with CCD imaging chips. The large format 3" field flattener screws directly to the rear of the focuser (the 2" push-fit adapter can be removed) to reduce flex in the imaging train with threaded-only connections, resulting in tighter star images, and sharper images. A conical rear adapter with an M48 rear thread is included, and the correct spacing for Nikon or Canon EOS DSLR cameras can be obtained with the special Altair Astro low profile Canon DLSR adapter, or the standard Skywatcher Nikon M48 DSLR adapter. If you have a CCD camera, our variable M48 spacers can be used to get the right distance to the CDD chip. (See associated products below for the Altair Planostar 3" field flattener).

3" Focuser for astro-imaging: The large format rotating 3" CNC machined focuser offers a rigid and stable platform for imaging use. The pushfit adapter accepts all 2" accessories for visual use, such as star diagonals. It features 3x clamps, and a brass compression ring, offering increased rigidity compared to single screw designs. The focuser can be fully automated and motorised within minutes with the optional USBnStep motor focusing systems we offer separately. We are currently testing an optional Starlight Feathertouch focuser is also now available to fit the Altair 102-715 and Altair 130-905 EDT APOs which all use the same focuser. Our USB nStep motor focuser unit is also offered with adapter set to fit the Starlight Feathertouch 3" focuser available separately. Please enquire as to pricing and availability for these options.

Altair Wave Series 115 F7 ED Triplet APO

The Altair Astro 115mm F7 EDT APO is a highly specified triplet APO refractor which significantly outperforms 4" refractors both in resolution and light grasp, whilst still remaining quite portable.

The Altair 115mm F7 EDT is the ideal multi-purpose telescope platform, suited for the amateur astronomer interested in both visual and imaging use, and offering excellent performance in both areas. It offers a wide-field or a high power view and is therefore more versatile than a Cassegrain type reflector, enabling high contrast views of planets and wide field deep sky objects.

The large format 3" field flattener screws directly to the rear of the focuser (the 2" push-fit adapter can be removed) to reduce flex in the imaging train, resulting in tighter star images, and sharper images. A conical T-thread adapter is included which screws into the rear of the focuser, with the correct spacing for Nikon or Canon EOS DSLR cameras. All you need is a camera adapter to attach your DSLR.

3" Focuser for astro-imaging: The large format rotating 3" CNC machined focuser offers a rigid and stable platform for imaging use. The pushfit adapter accepts all 2" accessories for visual use, such as star diagonals. It features two clamps, putting pressure on a brass compression ring, offering increased rigidity compared to single screw designs. The focuser can be fully automated and motorised within minutes with the optional USBnStep motor focusing systems we offer separately. NEW An optional Starlight Feathertouch focuser is also now available to fit the Altair 115-805, as well as the Altair 102-715 and Altair 130-905 EDT APOs which all use the same standard focuser. The motor focuser unit is also offered with adapter set to fit the Starlight Feathertouch 3" focuser available separately. Please enquire as to pricing and availability for these options.

The Altair 115mm APO sports a triplet air-spaced lens cell for better colour correction than normal doublet or dual lens telescopes. This results in higher contrast, and a cleaner sharper image with less spurious colour. The combination of a triplet ED lens system with high surface accuracy and the fact that this telescope does not have a central obstruction like a reflector telescope, means that it will deliver increased contrast compared to a reflector telescope such as a Schmidt Cassegrain or Newtonian of slightly more aperture, revealing more detail.

We will not be able to repair cases which are scratched or dented or have absorbed knocks, because it isn't economically feasible. To put it another way we consider the case to be expensive packaging to protect the optics, and if it's dented, then it's doing it's job. We do of course guarantee that the telescope arrives in perfect working order, and delivery is fully insured by courier!).

Skywatcher Evostar ED80 DS-PRO Package

The new EVOSTAR DS-PRO Series ED Apochromatic refractors in their stunning Black-Diamond livery, house premium optics of the same quality and performance level as our legendary Equinox series, making them superb instruments for both imaging and visual observations.

Apochromatic Refractors, due to their unobstructed, text-book like diffraction patterns, produce the sharpest, highest quality optical imaging available, bar-none, aperture for aperture, of any telescope optical system.

These high-end telescopes all feature a doublet objective lens. One element is made from premium Japanese Ohara FPL-53 Extra-Low Dispersion (ED) glass, which virtually eliminates chromatic aberration to deliver true colour reproduction. Top quality Schott glass is utilized for the Crown element.

Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied, to ensure optimum light through-put of approaching 99.5%!!

The proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHC) are the finest photon anti-rejection coatings in their class.
