The Crescent Nebula
Another take on this favorite, rendered here by Hydrogen Alpha capture which brings out the red hydrogen rich regions of summer nebulae. I wanted improved stars compared with my last outing and used both a new adapter and coma corrector, which seems to have worked well. I also used the new PI Starnet neural network module during processing to separate the stars from the nebula and I can see how this will be a very powerful tool going forward.
Tech stuff: Borg 71FL/TV 2XPM/Baader MPCCIII/Astronomik HA filter/QHY163mono/iOptron CubePro 8200 guided 160 minutes About half of data was captured with 15 second exposures, half with 60 second exposures, LiveStacked into 8 minute stacks with SharpCap Pro. Processed with PixInsight, GIMP and ACDSee. Captured in 2 nights July and August 2019 from my yard 10 miles north of New York City.
