What size extension would I need to connect my ASI183MC Pro to an Orion Astroview 120ST to get the proper focus to the camera.
Thanks!
The best solution of 55mm back focus length for your reference https://astronomy-imaging-camera.com/tutorials/best-back-focus-length-solutions-55mm.html
Is the 55mm back focus the same if I want to connect the camera to Celestron CPC 800? Thanks!
