Mars – First pass on processing

Hi Folks

Here’s my first pass at processing some Mars image runs. I’ve been a bit too gentle on the processing this time round so I’ll go through again. The polar cap and some of the surface is starting to appear nicely. I need to get a better Barlow though.

The data set I’ve got to work with is 3 image runs totalling 15000 subs, taken with ZWO 170MC and Celestron 8SE with a x2 Barlow

NGC 7000 (North American Nebula) Gulf of Mexico region 21/9/2020 processed 23/9/2020

  • Photos taken in Lichfield, UK, 21/9/2020
  • Altair Astro 138M camera
  • LRGB filters
  • This image from RGB without luminence data.
  • Sky Watcher Equinox 80mm OTA
  • EQ6 mount on mobile platform – rolls out on my garden!
  • Guided in PHD2
  • Stacked in Deep Sky Stacker
  • Processed in PixInsight and Photoshop CS6

The picture is a little noisy – but worse still is the nasty green light pollution gradient – everything I try to remove it also takes out the nebula – suggestions please!
