Description

This one was a pretty good learning experience, took a lot of research & practice with pixelmath to blend the H-Alpha data in with the Luminance & Red channels, but that was basically the whole point of this image - to show all of the Hydrogen regions/nebulae within Andromeda’s spiral arms.

Exposures as follows:

51 x 5 minute shots through a Luminance filter.

40 x 20 minute shots through an H-Alpha filter.

27 x 10 minute shots through a Red filter.

27 x 10 minute shots through a Green filter.

33 x 10 minute shots through a Blue filter.

All data was binned 1x1, captured at a scale of 0.82 arc-seconds per pixel & calibrated with 25 Flats, 20 darks & 20 bias per filter.
