This corrector is optimized for the Artesky APO80EDF7 refractor, however it can also be adapted to other refractors up to focal lengths of F/7.5 by changing the backfocus distance. It returns excellent images even with very large sensors without issues; backfocus from the T2 thread is 55mm for the 80mm F/7.0 model. You can connect a 2" filter in front of the corrector.
