Extension of the light tube for more even illumination of the image field.
Suitable for 8" RC telescopes from TS, GSO, Astro-Tech, etc., built before 2021.
The light shield of RC telescopes is very generously dimensioned. However, when using larger sensors, stray light can pass through the light shield and into the camera in older telescopes. The result is ring-shaped or arc-shaped brightening, which can only be eliminated with a FLAT.
This extension made of matt black filament extends the light shield tube and thus prevents stray light from entering. The image field is illuminated more evenly.
Attaching the extension is easy; it is inserted into the light shield tube from the front and holds in place by itself. The light shield extension itself is ultra-light and, when fitted carefully, does not affect the collimation of the RC. You can start taking photographs straight away. The extension can remain on the light shield.
Note: The light shield extension is only suitable for RC telescopes manufactured before 2021 and without the conical tip on the light shield.
TS Optics is a brand of Teleskop-Service.
