I have used this adapter for 3 years on everything from DSLR to CCD in refractors and SCTs. It is a mainstay of my imaging equipment. It is rugged and allows 2 inch filters to be used in the image train. It is a must have for any imager.

Do you sell a T-ring for Pentax K mount cameras to use with this 2" adapter?
Hello Chris! I´m a regular customer from OPT, and I have a Nightscape CCD Camera and I´d like to adapt the Astro-Physics CCD Telecompressor in this camera...the nosepiece which comes with this camera won´t fit...which adapter I´d have to use? Thanks a lot !
Are the external threads (camera side) 2.150 x 24UN-2B? I need one to attach to my QSI690 with the 2.156 adapter plate. I also need to screw in my Astronomik CLS 2" filter (M48).
which t adapter do I need for a explore scientific 102mm and nikon d5100 dslr
Does this have the safety undercut on the barrel? The top picture is without undercut, the description picture shows an undercut.
