IC59

An LRGB image with Ha blended into the red and lum channels. The Ha is quite intense in this region so I only blended a small fraction into the red channel in order not to overwhelm the other colours.

The image is cropped and rotated in order to highlight a "blue dove" that I saw when processing the image.

I was also experimenting with a lower exposure time of 20min Ha subs. These didn't appear to make any difference to efficiency of gathering data, so in future I will stick with my default of 30mins.

LIGHTS: L:16,R:10,G:14,B:18 x 600s; Ha:34 x 1200s, DARKS:30, FLATS:40, BIAS:100 all at -20C.
