M 101 Pinwheel Galaxy (under a 82% Moon)

04 April 2020

I already took an image of M 101 and I thought I would be able to get a somewhat decent image even under a nearly full moon. But boy have I been wrong and I hope to have learned at least some basic things for the future:

  • A moonlit night is not the right night to make deep sky images with any other than narrow band filters.
  • Galaxies (with the exception of M 31 and perhaps M 33) are no suitable targets for what an astrophotographer calls a wide-field image.

But apart from the fact that the final result is far from what I had hoped for - I certainly had fun and after all that's what it's all about.
