Can anyone tell me the diameter and thread on the AO8 opening (also looks like it matches the thread on the largest adapter plate for the SC2). Looking to get a threaded adapter that fits and downsizes to an M48 ring. Thanks!
The adapter plate that comes with the AO-8 has a T-thread, and includes a 2" thread-in eyepiece barrel adapter. We also offer a 2" nosepiece adapter that has a larger opening than the T-thread. https://diffractionlimited.com/product/ao-8-2in-nosepiece-adapter/
