Astrophotography – deep sky

Iris Nebula

Probably spent far too long processing this one, but I really wanted to try and bring out the dust. Still not quite happy with it, but been looking at it too long and need to walk away- for a while at least! Also noticed that there was a touch of tilt on the stars. I spent a while adjusting it… and I’ve made it worse!! So much for my DIY skills.

This is an 1 hr 20 minutes data from 14th. 30 second subs at 250 gain in SW200p- 20 mins of Blue and Green and 40 mins of Red (it clouded over before I got to the blue and green second time around!)

  • 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!
