Another experiment, this being the first time I've done 10-minute subexposures. I seem to have captured quite a bit of detail for just 90 minutes of total exposure time. The purple-ish cast all throughout the nebulosity comes from internal reflections in the QHY8 camera and is a common but unfortunate side-effect any time very bright stars are imaged.

If you look closely near the bottom center, you'll see tiny little PGC 13696, a 17.3-magnitude spiral galaxy.

Taken at the ASKC Dark Sky Site about 75 miles south of Kansas City.
