Description

I am a Galaxy guy. No way denying it. This was way more fun than my Crescent Nebula experiment. I should have spent a few more hours on this beauty.

Still quite noisy because
  • shot during full moon
  • in the last hour of twilight before astronomical darkness
  • at 20C temperatures with an uncooled camera.

Adding the data from May from experiments with my small 3" f/9 reflector really helped. The 300s subs are from the C8 + D3400 and the 180s data is from the Omegon 76/700 + ASI224MC.

I am going to revisit this next spring. Looking forward
