Adapters
T thread adapter for finderscopes - £28


Designed to connect the QHY5 and QHY5v cameras, via their T threads, to Skywatcher, Celestron and Orion 8 x 50 and 9 x 50 straight through finderscopes.
Tests have confirmed that guiding is successful at focal lengths of around 1000mm and more. Using the finder as a guidescope reduces the weight and complexity of your imaging setup and the wide field of view virtually guarantees aquisition of a guide star.
Image shows a QHY5 connected to a Skywatcher 8 x 50 finder using this adapter.

Dew Control by Dew-Not, high efficiency, low power heating strips.
Made in the USA the Dew-Not dew remover is a thick film heater made for operation at 12 volts.
Sixty-six percent of the surface area is heat emitting - meaning more even heat distribution and no localized hot spots. Covered by over 30 US and international patents, and with more than 20 years of improvements and enhancements, the Dew-Not dew remover is reliable and efficient.
Each heater strip comes with a standard six foot cord and phono-plug connector. A suitable 12 volt DC supply is required (either via mains transformer or battery) and a supply connector cable or controller.
Using 50 - 75% of the power of other dew heaters it's now possible, in many situations, to dispense with the additional cost of a controller and to use only an inexpensive fused supply cable.

Flip Mirrors
BrightStar (BS-Astro) Modular Flip Mirror - £89
Advanced flip mirror system that allows flipping between camera and 1¼" eyepiece to precisely centre an object at high power. Useful for correcting GOTOs and for high power planetary imaging where the field of view is small. The use of T threads throughout makes this very versatile as adapters are available for many of the most common camera and scope fittings. The unit is supplied with a 1.25" nosepiece, 1.25" eyepiece holder and a male T thread which has a locking ring for camera orientation. Can be collimated by the user.
Not suitable for most Newtonians due to lack of back focus.

Not suitable for most Newtonians due to lack of back focus.
Focal Reducers & Correctors
Variable Power Focal Reducer .4x to .8x (1.25") - £24
If used with a webcam or DMK this simple and cost effective device works at around .5x reduction. Used with a short C mount adaptor and a Mintron or Watec it provides .6x to .66x reduction and .4x to .5x with the longer C mount adapter. For DSI, QHY and other cameras the exact reduction ratio varies with the spacing from the CCD chip, if sufficient focus travel is available. This depends on the telescope and can be altered by using different adapters. The reduction ratio is variable from about .4x to .8x Larger and "slower" instruments (F7+) such as SCT's and MCT's really benefit from using this focal reducer and achieving focus with them is not usually a problem. Brightens images and increases field of view with almost all scopes. Increased FOV makes GOTO's more reliable and reduces the visibility of tracking errors. Can be used visually in many eyepieces and accepts 1.25" eyepiece filters. In our tests this reducer outperformed other 1.25" reducers on the market in terms of image quality.
Multi Purpose Coma Corrector - from £102
The Baader MPCC improves image quality for F4 - F6 reflectors. Fits 2" focusers and has a rear T thread. Covers 35mm format.

Sky-Watcher 2" Field Flattener - Field Flattening Lens - £69
Superb quality, non-focal reducing Field Flattener optimised for DSLR imaging on refractor telescopes with focal ratios of between f/5.5 to f6.0. Will also provide much improved results on refractors with focal lengths narrowly outside this optimised f/range. Integral T-Ring adaptor thread. High quality CNC machined body with gloss black anodised finish.
Sky-Watcher 0.85x Reducer - £149
Designed for serious Astro-Imagers. Optimised for the Evostar-80ED PRO, Evostar-100ED PRO and Evostar-120ED PRO this superb quality accessory effectively reduces the telescope's focal length by a factor of 0.85x and provides much improved field-edge correction. For DSLR cameras use in conjunction with SkyWatcher’s M48 Canon or Nikon T-ring.
TS 2" Field Flattener - Universal Field Flattening Lens - £199
A flat field imaging corrector for ALL refractors with a 2" focuser, producing pinpoint stars from centre to edge! The flattener has an optical diameter of 45.5 mm and offers reduced vignetting compared to narrower T2 types. Optimal spacing varies with F ratio and is 100 to 105mm for F5, 103 to 109mm for F6.6 and 105 to 110mm for F7.5 scopes. Fitting is M48 at both ends. Please ask if unsure about adaptation and spacing!

- Precisely aligned focusing drawtube, no loss of alignment when tightening the locking screw
- Smooth focusing motion even under heavy loads of up to 4kgs
- 1:10 dual speed microfocuser for fine focusing

Nosepieces
Standard 1.25 inch Nosepiece for T thread cameras (Atik, Lumenera etc) - £15
This is the standard nosepiece for Atik, Lumenera and other cameras with a female T thread. The nosepiece is male T thread to male 1.25" and connects any T thread camera to a 1.25" focuser.
Short 1.25 inch Nosepiece for T thread cameras (Atik, Lumenera etc) - £12
This shorter nosepiece was designed to facilitate the use of the Atik and other 1.25" screw in reducers with reflectors and telescopes having either limited focuser in-travel or "fast" F ratios. By bringing the reducer closer to the CCD it also provides a lower reduction ratio than the standard nosepiece. The nosepiece is male T thread to male 1.25" and connects any T thread camera to a 1.25" focuser.
Off axis guiders
Baader RCC Off Axis Guider - £118
40° swivel Off Axis Guider (OAG) with T2 thread connection. This OAG was developed especially for the RCC I Rowe Coma Corrector (for Newtonian Telescopes). Using this OAG and a Baader T ring, you can guide any DSLR camera with no additional extensions of rings, or "Off Axis" by using a reticle eyepiece or LVI Smartguiders. (You'll also need a T-ring to connect your dSLR to the T-thread. It's specific to each camera type/brand.) The ideal chip spacing arises automatically by the optical height of the T-ring and the RCC OAG.
Brightstar Astro Off Axis Guider - Only £99 Delivered !!!!
The Brightstar Astro Off-Axis Guider lets you image and guide simultaneously through the same telescope eliminating the need for a separate guidescope,saving equipment weight and setup time. Imaging and guiding through a single telescope eliminates tracking problems such as differential flexure and mirror shift. Compatible with autoguiders featuring T-threads or 1.25" nosepiece, as well as 1.25" illuminated reticle eyepieces. Works verry well with the QHY5 and QHY5v. Attaches to any 2" focuser via the included 2" nosepiece, or onto any T-thread equipped rear-cell. Includes T-extensions of three different lengths (7mm, 17mm, and 30mm) to accomodate different camera/guider combinations and has prism tilt adjustment and more than 100 degrees of radial adjustment for easy guide star location. Built-in coarse and helical fine-focus adjustments allow focus of autoguider relative to camera. Requires a minimum of 59mm inward focus travel. Not recommended for reflectors due to their limited focus travel, use the TS 9mm OAG instead. Brightstar make many accessories for famous name manufacturers and this item is also available as the Orion Deluxe Off Axis Guider.
TS Off Axis Guider - only 9mm length - T2, EOS or M48 fitting - from £189
The TS Off Axis Guider is the lowest profile off axis guider, making it perfect for use with many Newtonians. Despite this, no compromise has been made with the function and operation of this versatile Off Axis Guider.
No mechanical flexure between main and guiding telescope can ruin tracking accuracy if you use an off axis guider.
The load for the mount is much reduced, there's no need for a guide scope, and the setup remains more compact.
You work with the main telescope's aperture and focal length, not with the smaller aperture of a guide scope.
Compared with many simpler guiders the TS OAG not only has a shorter overall length, but also a larger clear aperture. A "T2 keyhole" is avoided, resulting in better illumination for large sensor cameras up to 45mm diagonal.
