Description

My first attempt at boosting red with Ha. Only got an hour of Ha as I ran out of darkness. Want to get more Ha and possibly Oiii to help boost the blues.

B

Description: More core detail in the galaxies, and better stars. Toned down the IFN to make it feel "more natural" and to make the galaxies pop a bit.

Description: After a few weeks of learning about drizzle, deconvolution, and HDRMT in PixInsight, I went back to this image and tried to extract as much detail as I could. Particularly happy with the dust lanes in the galaxy cores. Much more of a documentary presentation (and less of the discotheque presentation in version C). Need more time on target to bring out those blues and the IFN without overcooking the data.
