My first posting here for quite some while...
This image apture was with some of my older kit but processed in PixInsight using modern tools available now.
Capture was with a Samyang 135mm lens fully open at f/2 and a 2 second exposure at ISO 40,000 with an astromodified Sony A7S. Unfortunately to reach focus I had to use a Baader Neodymium filter which added unnecessary filtering.

Oh Wow, so great to get these targets below our UK horizon.
Is this really only a 2 sec exposure in total? Not a batch of 2 sec exposures stacked? If so amazing.
Yes Carole it was one 2 second exposure with the camera on a tripod. SQM reading overhead was 21.9 at the time but not quite so good where the exposure was taken.
