TS-Optics REFRACTOR 0.8x Reducer Corrector (TSRED80)

Description

TS-Optics PHOTOLINE 2″ corrector and focal length reducer for astrophotography with 80 mm f/7-f/7.5 ED and APO refractors
This corrector is optimized for APO and ED refractor telescopes with 80 mm aperture and an f-ratio of f/7 to f/7.5. It delivers very good results with these telescopes. even with larger sensors the stars look sharp and round across the whole field.

The corrector is simply inserted into the 2″ receptacle of the refractor and fixed. since it does not have a safety notch tilting will not be a problem.

Distance from T2 thread to camera sensor:
The backfocus from the camera-sided T2 thread to the sensor is exactly 55 mm. If you want to connect a DSLR you will need the appropriate T2 ring. For almost any astro camera, e.g. from ZWO, fitting adapters are available. The most important adapter rings are linked in the accessory section.

Usage of smaller refractors with smaller aperture and/or shorter focal length
This correctors also delivers good results with smaller refractors. We also recommend this corrector for 70 mm and 72 mm f/6 refractor telescopes. The optimal distance for such telescopes is 63 mm from the T2 thread. In order to adapt a DSLR camera, you will need a T2 extension with 8 mm (TST2V8) and of course the T2 ring.

Attachment of nebula filters for astrophotography
On the telescope-side the corrector offers a M48x0.75 – 2″ filter thread. With it you can attach all customary nebula filters.
