Description

REV. A) July 2017

25x120" Gain 0 / Offset 10 @ -10degC.

ASI1600MC-C with VC200L (focal reduced x0.71, ~1278mm FL)

200 bias frames @ 0.3sec

60 flats frames @ 0.4sec

39 dark frames (120sec x -10degC)

2x2 binned

M27 is a common object, but it is useful for calibrating color reference and general equipment performance relative to others.

REV B) This version is 53x120" (including the 25 from Rev A). There is a faint bit more detail of the nebula (particularly "waves" on the right side in this view, and a wisp beyond the "apple core" portion). But this version was also processed somewhat differently, which is the main reason for a more overall "brightness" increase and more stars to be present.

53x120" Gain 0 / Offset 10 @ -10degC (and all same equipment)

REV C) This is 73x120", same setup, but taken nearly 11 months later (201. 0/10, -10degC.
