Description

Old data from 2017. At that time I had my first try with the C8. In order to avoid saturation I did quite short exposures. However I should have done more subs. These galaxies are bright but need more data nevertheless.
For me the gold standard is https://www.astrobin.com/v0563e/
but of course the data are not the same and I don't have Christoph's skills. All in all it was  fun to process these old data.
Clear skies and peace,
Andreas
