A combination of 15 hours of data from 2013 with my Ceravolo 300 and U16M at Astrofest and approx 13 hours of data from Martin Pugh's RH305 and STXL-16200. Processed in PixInsight, of course
NGC7424 is low surface brightness and quite a challenging target. I think this is a nice improvement over my 2013 version and 2015 repro. I'm looking forward to the 2019 version which should be really nice
