NGC4945 August 2022

Posted by Evolved Inspired on Sunday, August 28, 2022

Challenged with a moonlit sky but a new camera to get familiar with (QHY533C) the target NGC4945 provided a reasonable target.

I have been experiencing some star ‘bloat’, however realising the .75 reducer increases the back-focus requirement to 80mm I’m hoping to fix that shortly when some extension tubes arrive. The QHY533c from sensor to plate is 17.5mm of back-focus, so just around 62mm of back-focus to find.

NGC4945 or Caldwell 83 is a spiral galaxy within the Centaurus constellation in the southern sky

Anyhow here is a wider and cropped version of NGC4945
