Description

NGC281 Pacman Nebula

Original/final version: 12x600" 800ISO with 450D (UV/IR LPF2 mod). Taken 2014 October 4th from a red zone backyard (VMC200L 8" on AVX). Using 50mm SSAG with f/6.2 reducer. PixInsight 1.8 stretched. Didn't do the Decon quite right in PI (bad mask). CurveTransformation stretch in PI, didn't bother with AT or DBE. Light images were 4degC (as reported by the camera sensor), pretty cold for me.

For reference and future comparison:

Version B: My first NGC281 attempt in 8/10/2014, with no flats (7x300 ISO400). No reducer makes the scope at f/9.75, very slow for a red zone.

Version C: Same day and equipment as Original version, but 14x300 ISO800. This version was done before the meridian flip (so it is facing East, final image flipped to match). The setup wasn't as good. According to original data files, Version C was midnight-2am, Version A (marked Original/final) is later at 3-5am.
