The T2 to 2" photographic adapter allows you to connect all cameras and accessories with a female T2 (M42x0,75) thread to the Prima Luce Lab 50.8mm visual back.
On the telescope side it has a 48mm thread to allow you to screw any 50.8mm (2") diameter filter and has 39mm of free aperture, so cameras with large sensors won't suffer any vignetting.
