2x1 mosaic of H-alpha (red), S-2(green), and O-3 (blue) exposures. About 3.5 hours for each half. It needs much more O-3 data to show some blue and more S-2 wouldn't hurt either.

It's definitely working for you, for sure. Yeah, I'd just like to put together a more portable kit with the the Megrez, so it'll most likely be amongst my up and coming purchases.

I love th Flat 4! Of course, that doesn't mean it will work well on another scope, but most people seem to have pretty good luck with it.

Nice capture. How are you liking the Flat 4? I've been thinking about picking one up for my Megrez.
