I was almost free of the imaging itch, but then got suckered back in...

Thanks for the tip. I've been trying to research the 1.25-inch vs 36 mm filter issue online, and so far it seems like I might be okay with my f/7 scope. Atik claims that anything slower than f/5 will be fine because their filter wheel is very close to the 383L+ sensor, and the RGB flats I've seen posted online with f/7.5 scopes don't have any vignetting issues. I'm not sure whether 3 nm filters would be okay though - I've come across speculation that it could be problematic.
