Description

Version A: 8" scope, taken in red zone (very light polluted). 6x180" ISO400.

Version B: taken at a dark site, 2X Drizzle (5x180" ISO800); in the post processing, a tiny bit of galaxy IC1296 starts to appear.

Version C: is a new attempt at the original/A version data (6x180" ISO400), using PixInsight instead of DSS/CS2.

Version D: Taken from backyard red zone 2015, VC200L instead of VMC200L. 15x300" ISO400. Think 300" is over-exposed.

Version I: With VC200L taken 2015/07/16. 25x180sec
