Starwave MiniGuider 60 Side-by-Side dovetail bar kit for refractor auto-guiding

Now you can mount your wide field refractor of up to 80mm next to your autoguider unit, whilst keeping the centre of gravity as close to your mount as possible.

This is the ideal kit for someone starting imaging with a refractor up to 80mm. The perfect companion for the Starwave 70ED refractor and the iOptron ZEQ25 mount!

Starwave MiniGuider 60 Side-by-Side dovetail bar kit consists of:

The renouned Altair Astro 60mm Miniguider OTA, with special super-rigid locking focuser for your autoguider.*
Starwave 1.75" (44.45mm) width dovetail clamp to mount your refractor on one side.
The Starwave 200mm 1.75" (44.45mm) width Vixen-format dovetail plate which fits most portable mounts on the market today.
A set of mini guide scope rings with nylon tipped screws to mount on the opposite side of the dovetail bar, with connecting bar, to mount your 60mm Miniguider.
A set of M5 screws and nuts to mount the Miniguider 60 rings, and a set of M6 screws and nuts to mount the Starwave1.75" format clamp.
Features:

Can easily support refractors up to 80mm and will accurately guide up to at least 1000mm focal length without differential flexure.
Keeps your telescopes low and spaced widely enough apart such that the cables and autoguider unit can be adjusted easily without interfering with the main camera, unlike "piggyback setups". This is desirable when imaging with a DSLR enabling it to be easily rotated it when framing the subject. without fouling the autoguider unit.
The centre dovetail bar can be slid from side to side for easy balancing.
The Starwave Vixen-format clamp is strong yet light, with 2x spring loaded 2x steel alignment pins. The CNC machined e-coated knobs feature Teflon washers to stop binding. It also has a 1/4" UNC camera tripod thread on the underside, so you use it to mount your telescope on a camera tripod for casual stargazing, or daytime observation.
The Altair 60mm Miniguider probably needs no introduction. It's widely acclaimed for it's simplicity and accuracy, and is far easier to use than an Off-Axis-Guider (OAG) unit. It doesn't take up space in the imaging train, and require more adapters and calculations, nor does it cause flexure problems, due to it's unique locking focuser, with 3x clamping screws and brass insert. Selecting from a huge field of stars is easy at a very fast F3.75 so you don't need such a sensitive autoguider camera - and what's more, and theres no pickoff prism to intrude into the light-path of your full frame DSLR. Nor does it add flexure to the imaging train, or need to be frequently focused, unlike some cheap OAG units. Simply add your guide camera, set focus, and tighten the locking ring, and that's it. The Miniguider doesn't even need to point in exact the same direction as the main telescope so you can move it around in the (extremely unlikely) event you can't find a bright star.
The Starwave 200mm dovetail bar is strong, solid and more rigid than the cheap extruded rails often offered with guide-scope kits, and will fit the majority of mounts on the market.
* Do not be tempted to buy a finder-scope with a helical focuser for autoguiding. They focuser loses it's focus easily, and they aren't rigid enough for autoguiding due to the play in the helical mechanism. They are OK for eyepieces but not for autoguiding. We researched this thoroughly, and it's why we developed the superb Altair 1.25" locking focuser.

Skywatcher Off Axis Guider

Designed for use with DSLR and CCD cameras, this low profile Off-Axis guider is a convenient alternative to using a separate conventional guide scope for astrophotography, offering several advantages.
More precise tracking as mechanical flexure and image shift are eliminated from the system. The main camera and guiding camera will always move accurately together.

The overall system is much lighter and more compact as a separate guide scope is not needed.

Brighter, higher resolution images of the guide star on the guiding camera, as you are viewing through the main telescope. Easier to notice and correct tracking errors.

Supplied with 2 to M48, and M42 to 2 adaptors.

Profile approx 12mm

Altair Astro 6" RC & 8" RC Focuser Collimation Adjuster

Designed to give the perfect image field when imaging with your Altair, Orion or Astro Tech 6" or 10" Ritchey Chretien, by making the focuser completely orthogonal to the telescope's optical axis.
Adjustment to fractions of a millimeter are possible for a perfectly flat field with optimal off-axis image sharpness. No more hunting the "sweet spot" for your particular setup. The focuser collimation adjuster is ideal for use with larger CCD chips (APS and above) as well as field flatteners and reducers, where deviation from the focal plane edge is more critical.

The focuser collimation adjuster fits between the focuser and telescope. It can be adjusted in real-time for best results, using the easily accessible push-pull collimation screw system at the sides. It will not foul the standard RC focusers, nor the Starlight Feather Touch focuser upgrade. For the perfectionist, it's possible to use CCD Inspector to derive the exact amount of focal plane tilt as a numerical value, and to adjust it out completely.

The Focuser Collimation Adjuster adds 15mm to the optical path.

Mounting the focuser collimation adjuster is easy:
1) Remove the focuser.
2) Screw on the collimation adjuster.
3) Re-attach the focuser or RC focuser extension tubes, should you require them.
4) Use an Altair v2 Laser Collimator and Altair Self Centering Adapter to adjust the push-pull screws, placing the laser beam on the secondary mirror centre-spot.
5) Now you can fine-tune using the CCD camera preview mode or CCD inspector.

Altair 10x60mm Right Angled Illuminated Finder (erect image, variable illuminator, finder bracket, multi-purpose base)

The Altair Astro 10x60mm finder scope is a larger and more powerful upgrade to standard 8x50 finders.

It gathers more light, resulting in a brighter image delivering almost half again as much light to your eye. Many more objects are visible in this finder than in standard 50mm finders. The Altair Astro 60mm finder also has several more features:
This finder is right angled for more comfort, with a corrected field (i.e. not mirror-reversed like other finders), so objects actually match their orientation in your star chart.
The focuser can also be rotated 360 and locked in seconds (requiring some re-alignment afterwards). The 10mm larger objective and a little extra power compare to 8x50 finders, yet has almost the same size and weight.
The included quick-release finder base has 4x 4mm slotted holes in the base allowing you to fit it to most telescopes on the market, such as Celestron and Meade, SCTs, refractors such as William Optics, Vixen, Skywatcher. (The mini-dovetail wedge on the bracket will fit any GSO or Skywatcher telescope directly in fact but we suggest you use the included base because it has 2x clamping screws, for better alignment).
The CNC machined bracket is light yet rigid to keep alignment. Nylon tipped screws do not damage the durable high quality and moisture resistant paint on the aluminium tube.
All objective lenses are anti-reflection coated and the tube and dewshield are internally blackened to increase contrast. The included illuminator has a variable setting, which illuminates the cross hairs in the eyepiece. The included eyepiece has a dark field illuminated cross-hair, so you can easily see it glowing faintly against the background sky, unlike the finders which usually come packaged with telescopes with have dark cross-hairs, making it hard to find objects.
The high quality 1.25 FMC illuminated eyepiece has good eye relief for glasses-wearers, and a wide field of view. It has a side-port to screw in the variable darkfield illuminated reticule, and the finder can be very easily focused, using the included helical focuser.
The higher 10x magnification is better for astro-imagers who want to centre an object more precisely in the camera field-of-view, yet the field of view is still very large.
With an extremely fast F3.75 doublet achromat lens operating at 225mm focal length, the finder tube performs very well as a micro-guider, or for use with an electronic eyepiece for remote real-time finding or remote alignment of your telescope mount. You can guide up to 1 metre telescopes.
Altair 60mm finder package contents:
23mm wide field eyepiece with illuminated glass engraved reticule.
CNC machined variable brightness LED illuminator, which plugs into the eyepiece.
Smooth 1.25" helical focuser - accepts any 1.25" eyepiece.
1.25" erect image prism.
60mm F3.75 multi coated doublet Achromat finder OTA with rotating rear assembly.
Special dual-clamp mounting bracket to fit most SCTs and refractors on the market.
Alu Tube rings with 6x Nylon tipped adjustment screws.
Mini-rail to connect the tube rings.
Tough foam filled carboard case.

Altair 60mm Miniguider with Autoguider Webcam focuser, tube rings, multi-purpose base

The Altair MiniGuider System is based on the very popular Altair 60mm Finder. The package includes a 60mm finder optical tube assembly, a special focuser for Autoguiders and Webcams, finder rings, universal bracket and stalk.

The autoguider focuser is available separately as an upgrade for customers who already have the Altair 60mm Finder, and who would like to use it for autoguiding with a webcam or autoguider head such as the QHY5, Orion USA Starshoot, or any other autoguider with a 1.25" barrel.
The product is designed to provide you with a stable platform to attach your autoguider or webcam, having to use a separate telescope. Any webcam or autoguider with a 1.25" barrel will fit. The package is ideal for astro-imagers who have a wide field portable imaging system and will work well with telescopes up to 1 metre focal length. This product is ideal for smaller capacity EQ mounts - by keeping weight down, you're putting less demand on your mount, and therefore tracking accuracy is improved.

The Webcam focuser can be rotated 360. The 60mm objective has a focal ratio of f3.75 and a focal length of 225mm. The fast focal ratio objective is the same as found in the Altair 60mm finder, and the Mini-Guider focuser can be purchased separately, or together with an Altair finder system.

The included quick-release finder base has 4x 4mm slotted holes allowing you to fit it to most telescopes on the market. The mini-dovetail wedge on the bracket will actually fit any GSO or Skywatcher telescope directly, but we suggest you use this included base because it has 2x clamping screws, for far better rigidity than standard finder bases on the market.

The adjustable tube rings are light, yet more than rigid enough to stay in perfect alignment for autoguiding. They cannot rotate like other cheaper makes because the dovetail bar they sit upon has a slight channel to accept their profile. Nylon tipped screws avoid scratching the durable high quality and moisture resistant paint on the 60mm aluminium OTA.

All objective lenses are anti-reflection coated and the tube and dewshield are internally blackened to increase contrast. This is a high quality F3.75 achromat objective, and it will deliver pinpoint stars on your finder chip on axis, performing at the resolution limit of a 60mm lens. It is far higher quality than the lenses found in cheaper, and smaller finders, and will perform extremely well at this fast focal ratio, keeping your exposure times short, and stars very bright with a small dot size - exactly what's needed for precision autoguiding.

Altair Maxi Guider 80 Guidescope Package

Here's an autoguiding package for customers who want a quality flex-free autoguider system, with a larger aperture than our very popular Altair Miniguider 60.
This will suit scopes with a focal length of around 2 metres or more, and is suitable as a "video finder" too. A very rigid set of Altair light weight guide scope rings carries the light-weight 80mm F4.1 guide scope optical tube assembly.

The Altair Maxiguider 80 Guide-Scope Package consists of the following:

- 80mm F4.1 achromat optical tube assembly with dew-shield and objective cap.
- 1.25" Lockable Auto-guider Focuser Adapter with 3x clamping screws.
- Altair 100mm Ultralight Guide Scope Rings (GSR-100).
- Altair 180mm Vixen Dovetail Bar (VDB-CL-180).
- 4x stainless steel screws to attach the GSR100 to the Dovetail bar.
- a 1.25" RACI diagonal with helical focuser (suitable for use with a 1.25" eyepiece).

You can choose black anodized Guide Scope Rings and corresponding 180mm Vixen format dovetail bar instead of the default silver, from the options list below.

This is a very good intro price for what you get, and we will try to maintain it for as long as we can, but it could increase soon.
