0.55 arcseconds/pixel. Image is 27' wide. North is right (mirrored).

  • Color: 27 minutes (319 * 4 seconds) through thin clouds
  • Equipment: C9.25, 0.63 reducer, ASI533 MC (IMX533 sensor), EQ6-R mount.
  • Resolution: 5 arcsec FWHM

I just can't seem to take a good picture of this region. This one has:

  • Messed up backfocus and collimation
  • Bad seeing, made worse by looking over the roof of my house
  • Every *single* 5-second frame was ruined by clouds.
  • I coudn't see Polaris so mount alignment was done based on memory

This was the best night I've had all month: There was one moment where I could actually see Orion in the sky... at least it's better then my last attempt where I cound't even find the object.

This is a heavly noise reduced version:

It looks a little better, but is missing a lot of the details of this object.
