I’m switching from using a 1.25 inch LPR (Light Pollution Reduction) filter to a 2 inch filter because I believe it will make my equipment more secure when it comes to mounting my DSLR (with T-Ring) and CCD cameras onto my Schmidt–Cassegrain telescope. I may also get a 2″ CLS filter in the near future, just to compare it to my LPR. The astrophotography equipment used in the video are listed below:
Optolong L-Pro Filter – 2″ Mounted
2″ – T2 Adapter Thread Outside
2″ SCT adapter
I used the NexStar 8SE telescope in this demonstration, but this system should work with any of the following Celestron telescopes: C5, C6, C8, C9¼ and C11 telescopes. When using a f/6.3 focal reducer, the reducer would go on first followed by the 2 inch filter.
