Almost every customer for our MRT adapter has asked, “This is great, but how do I attach it to my telescope?” The answer has always been that a direct threaded connection is best, but since most telescopes don’t have T-
The SCA is like a standard 2” nosepiece-
How it works:
The SCA is inserted into your telescope’s 2” eyepiece holder (either before or after attaching the MRT and camera). You then twist the knurled ring to expand the rings against the inside of the eyepiece holder. Done!
The SCA adds only about 19mm to the image path. As you can see in the picture to the right, the MRT setscrews are still accessible after threading the two pieces together, so in many cases you can attach or adjust the camera after the SCT/MRT assembly is installed on your scope. The SCA has its own camera rotation feature. It’s not as convenient as the MRT’s rotation capability, but in cases where the MRT’s thumbscrew cannot be used due to interference with the camera body, you can still rotate the camera using the SCA feature.
