Pleiades open star cluster, Taurus
12 x 7-min ISO 1600 autoguided exposures (taken 24 Sep 2022) and 7 x 7-min ISO 1600 manually guided exposures (taken 20 Sept 2015); astro-modified Canon 600D and Sky-Watcher ED 80mm f/6.25 telescope, piggybacked on a Celestron C8 telescope for guiding.
Frames stacked in Deep Sky Stacker software. Result post-processed to increase contrast, reduce noise and remove background colour gradients caused by stray light.
Unfortunately the pale red circles around the bright stars are reflections caused by the clip-in light pollution filter that I always use. I should really remove it when such bright stars are in the frame!
