The Eastern Vail Nebula

This is the Eastern Vail Nebula, made up by NGC6995 (left) and NGC6992 (right). Along with the Western Vail Nebula and Pickering's Triangle, they form the Cygnus loop in the Cygnus constellation. The Eastern Vail Nebula was once a star about 20 times the size of our Sun that went supernova 10-20 thousand years ago. The filament like structure of ionized gas and dust span approximately 130 light years and is 2400 light years away from Earth. This is a bicolor image using Ha and OIII filters due to the strong emission of ionized Oxygen (Blue/Teal) and Hydrogen (Red) molecules. The total exposure was 7 hours split from data taken in April from Bortle 2 skies in Texas and September from my backyard. This is one of my favorite images to date! More to come!🔭
