TS Optics PHOTOLINE 2" 0.8x reducer and corrector for 110mm f/7-f/7.5 ED refractors
This corrector is optimized for APO- and ED-Refractor telescopes with
110mm aperture and f-ratios of f/7-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
Distance from T2 thread to camera sensor
The backfocus from the camera-sided T2 thread to the sensor is exactly
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.
Usage of smaller refractors with smaller aperture and/or shorter focal length
This corrector also delivers good results with smaller refractors. We also recommend this corrector for 100mm and 107mm f/6 to f/7 refractor telescopes. The optimal distance for such telescopes is 60mm from the T2 thread. In order to adapt a DSLR camera, you will need a T2 extension with 5mm 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
Perfect sharpness and good illumination up to 30mm sensor diameter - ideal for apsc sensors
