Sadr Region

This nebulosity is known as the Sadr Region. It is located in the constellation Cygnus. The bright star is Sadr. Sadr is 1800 light years from earth, has a magnitude of 2.23, and is a Supergiant star. It is a little over 12 times the size of our sun. This image was taken using the SVBony SV220, a dual narrowband filter. To create this image I separate the Ha(red) and Oiii (blue) channels, and edit them seperately. I then recombine them using pixelmath. This is the first night of clear skies I have been able to set a scope out for in quite some time.
