Pickerings triangle (cloudy nights reprocess) I like to call this the Pizza Nebula as it looks like a slice of pizza with stretchy cheese. Named for the Harvard professor Edward Charles Pickering. Very interesting fellow to read on by the way. He had a team of only women help map all the stars and determine their measurements, temperatures and distances from each other and the earth. Amongst the women, 2 of them made huge differences in the way we understand the cosmos along with their team. These 2 women were Annie Jump Canon and Cecilia Payne. Cecilia Payne, known amongst scientists gave rise to modern day astrophysics and her studies are the standard text into it. She came from the UK to the USA during a time when women weren't allowed to take advanced studies of the cosmos in her home country. For more information on these great women and Mr. Pickering you can find it online. As for the nebula.... This is but a small portion of the ever expanding veil nebula (aka the cygnus loop) found in the cygnus constellation. The veil is a supernova remnant that exploded 3000 BC to 6000 BC. It now appears as clouds of ionized gas and dust. The distance to the nebula isn't 100% accurately known but the Far Ultraviolet Spectroscopic Exporer supports a distance of 1470 light years away. This was captured with a GSO Rc6, Zwo asi1600mm, 8 position electronic filter wheel, off axis guider with a zwo 290mm mini, astrophysics ccdt67 and a Stellardrive heq5 mount. Software for field work: eqmod, apt, stellarium, phd2 and plate solve 2. Calibrated and processed in pixinsight.
