Description

This is 9x90" at ISO400 (using 450D modified) on VMC200L 8" modified SCT, Celestron AVX mount. From the backyard red zone. Elonged stars on the right side of view either from uneven collimation or some sag in the focuser. Data from 11/29/2014. Integration included 240x count of bias images, 100x count of Flats, 30x darks.

Version A) from PixInsight with SuperBias integration and dark optimization. Version B) is a DeepSkyStacker comparison. Both saturation/other edits with PS CS6 (crop, shadow highlights, Level, etc). PI is quite a few more steps in processing, but helps reduce the background banding and makes the stars more "crisp".
