I'm still finding my way with this scope and camera, so just went with 10 min to help with Oiii. I used SGP for the 1st narrowband image I took of the Dragons, and it's exposure calc was suggesting ~15min for that target. Used 10 min subs on the dragon and just did the same for the Cat's Paw.
Not too sure what's the best sub length yet. Happy for suggestions.
