Back-Focus 101: Celestron EdgeHD: C9.25, C11, and C14 Basic Back-Focus for DSLR and CCD/CMOS Cameras

In this episode of Back-Focus 101 I cover the basics for attaching a DSLR camera or CCD/CMOS style camera to either the Celestron C9.25 EdgeHD, C11 EdgeHD, and C14 EdgeHD. These three telescopes all have the same back-focus requirement of 146.05mm whether you use the Celestron 0.7x EdgeHD reducer, or not. They also all have the same 3.25" large Schmidt-Cassegrain threads on the rear-cell. This episode just covers the basics. In the next episode of Back-Focus 101, I'll be going into an advanced imaging train for these telescopes, by installing the Celestron Off-Axis Guider, an electronic filter wheel, and monochrome camera. If you'd like to see how filters affect your back-focus distance, please check out the following episode of Back-Focus 101:    • Back-Focus 101: How Filters Affect Back-Focus   Please consider making your astronomy purchases from my Agena Astro and/or High Point Scientific affiliate links below.
