First try at a DSO with an uncooled CMOS Camera

This is my first try with an uncooled CMOS camera. I bought a ZWO ASI224MC a couple of years ago as I was intrigued by the images produced by this camera. I finally got around last night to try this camera out from my backyard. I've been using CCD's for DSO imaging for over a decade now and have been used to 10-30 minutes of exposure, so this was a most interesting experiment.

This is 21 images of 30-second exposures and 6 30-second darks. No flats or guiding, natural dithering from slight polar misalignment. The camera used was the aforementioned ASI224MC; scope is an AP130 EDFGT on an AP1200GTO mount. Images captured and preprocessed in Maxim, final processing in Photoshop CS5 with GradientXterminator and Carboni Actions. Shot from my light-polluted backyard under hazy, humid skies (red zone according to the CSC, but it feels like a white zone to me).

I'm impressed for sure.

Wow, Eric! This is a great image. I recently purchased this camera, mainly for planet imaging, and your image makes me feel like I made the correct decision.

Thanks, Carl! I bought this camera primarily for planetary imaging, but also because I saw a lot of really nice images taken of DSO's with this scope. I had hoped to try it for that purpose someday, I'm glad I finally got around to trying. And yes, I like what I'm seeing!
