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.
