Having dug out my images of Neptune and Triton from the blog archive in 2015 (https://roslistonastronomy.uk/neptune-and-triton)
I was looking at the other DSO images in the same post – M27, M57, NGC2403 (C7) and NGC 6503.
I thought I would have a go at reprocessing them with another 4 years of GIMP-ery under my belt, so here they are. Given recent dialogue about faint DSOs, tracking etc, it might be interesting to note that all these images are with a scope on an alt-az (ie not equatorial) mount with individual images in the stack of no longer than 20 seconds exposure.
I know that I keep banging on about the benefits of simple and cheap imaging but it IS a fact. For example, September “Sky at Night” says “- – – If you fancy a challenge, have a go at using a 250mm or larger instrument and a magnification of 250X and see if you can spot Neptune’s largest moon ,Triton. At mag 13.5 it requires good dark skies – – – -“.
Here is an image I got from from the light-polluted Midlands with the 8” SCT and PD a few years ago:
