Back-Focus 101: Celestron EdgeHD: C9.25, C11, and C14 Advanced Back-Focus with the Celestron OAG

In this episode of Back-Focus 101, I cover advanced back-focus for the Celestron C9.25, C11 and C14 EdgeHD Telescopes. I demonstrate how to attach the Celestron Off-Axis Guider (COAG), ZWO Electronic Filter Wheel (EFW) and the ZWO 2600MM Pro, all while still maintaining the proper 146.05mm of back-focus (or 147.05mm of back-focus when using filters). I also give my tips and tricks for setting up the COAG and which guide-camera I use with the system. The key to off-axis guiding is to remember that the main imaging train, and the guide imaging train need to have the same back-focus. 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.
