NGC1499 in Ha gray
« on: 2019 January 30 01:56:07 »
Here I worked up another set of data in PixInsight: 5 x 900s + 4 x 1800s at gain 0 with the 127mm and asi1600mcc w/5nm Astrodon Ha filter at -20C. At some point in the latter stages I  reintroduced some noise, will have to check out where. The file name tells what was done when.  C&C welcome:
Objects in the mirror are farther than they appear
