Product QuestionsQuestion by: STANLEY FORTUNA on Apr 3, 2015 4:28:00 PMWe do! Here is the link" http://www.optcorp.com/celestron-camera-t-ring-pentax-k-mount.html. The part# is CE-94303.Answer by: Chris Hendren (Admin) on Apr 6, 2015 7:01:00 PMHello 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 !Question by: DANIEL NOBRE on Jul 31, 2015 12:42:00 PMThis adapter, the OS-A2T, will fit your Nightscape camera and will thread into the CCDT67 reducer. The camera is 23mm long, the OS-A2T is 37mm long, and the metal back distance of the CCDT67 is 16mm, so the total spacing is 76mm in this configuration, which leads to 0.75x magnification [ (305-76)/305=~0.75x) ].Answer by: Chris Hendren (Admin) on Aug 3, 2015 10:37:00 AMAre 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).Question by: peter kubacko on Apr 3, 2017 10:16:00 AMDoes this have the safety undercut on the barrel? The top picture is without undercut, the description picture shows an undercut.Question by: jbauer on Nov 11, 2014 12:57:18 PMThe current version of this adapter does not have an undercut. The manufacturer told us that the undercut was commonly causing damage to brass compression rings that were not sufficiently loosened before the adapter was pulled out of the scope/adapter. With how common compression rings are these days, they decided to remove the undercut.Answer by: Chris (Admin) on Nov 14, 2014 10:53:30 AM
