The Standard T Thread to 1.25″ Eyepiece Holder with Additional T Thread converts any male or female T thread to a 1.25″ eyepiece holder or visual back. Can also be used as a 35mm T spacer.
The TS Universal 2-Inch Field Flattener for Refractors from f5 to f8 is a flat field imaging corrector for almost 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. Fitting is M48 at both ends.
For most refractors the optimum back focus distance is around 109mm from the M48 thread to the camera’s sensor.
Experience has shown that the flattener has a large tolerance for deviations from the ideal distance. A 5% deviation does not cause any deterioration of the image quality with an APS-sized sensor.
PS3-V Adapter adapts Vixen dovetails to fit 3″ Losmandy type saddles.
You own a telescope with a small dovetail (Vixen, Celestron, Meade, SkyWatcher etc) and you want to use it on your new mount with the bigger 3″ Losmandy saddle (Celestron CGE/M, Pro, Losmandy, 10Micron). Now you don’t have to remove the existing dovetail from your telescope, just slide the PS3-V adapter over it and hey presto, your telescope fits the new mount!
20.5mm – 30mm Variable T Spacer, very useful for finding the exact spacing required for reducers, coma correctors and field flatteners.
The image shows the spacer at the extremes of its adjustment.

TSRCFlat2 a 2″ corrector for f/8 RC telescopes – no effect on focal length
Suitable for all GSO RC telescopes from 6″ to 16″ and for all other F8 RC telescopes. Covers sensors up to full frame.
Filters for Astro-Video cameras are hard to recommend due to the relatively short exposures involved. After many tests this gentle Universal Contrast Filter (1.25″) has shown merit in reducing light pollution and increasing contrast on all objects.
It is effective mainly in areas where the local light pollution is due to Sodium (yellowish) light.
It’s also been found to be effective in revealing surface features on the planets Mars, Jupiter and Saturn as well as reducing glare when viewing the Moon.
M48 to 2″ EP Adapter, a 2″ Visual Back with M48 female thread, allowing the use of 2″ eyepieces on telescopes or accessories with a male M48 thread.
Please note this adapter is supplied with one set screw at the present time.
The TS PHOTOLINE 130 mm f/7 Triplet APO + .79x Reducer is equipped with one of the best lenses in its class. The apo element is the proven FPL53 from Ohara (Japan). The lens, free from chromatic aberration, is mounted in a temperature-compensated cell that also compensates for sub-zero temperatures. A solid metal tube and the new PHOTOLINE RAP 2.5″ deluxe focuser with rack and pinion drive make this apochromat a recommendation for the dedicated astrophotographer and the observer.
