New image in the making! These are two UNPROCESSED stacked masters still hot from over 10h in the number-crunching machine.
The target is the nebula complex around Sh 2-155 in the constellation Cepheus which contains a rich mix of emission, reflection and dark nebulae.
The data has been collected over two and a half nights, 8h24m using a broadband light-pollution filter (first image) and 6h42m using a Ha + Oiii dual narrow band filter (second image). The broadband filter captures the natural colors of the stars and reflection nebulae whereas the dual narrow band filter mostly isolates the hydrogen alpha emissions. My objective is to combine the broadband RGB signal with the hydrogen alpha signal into a single image. The third image is a rapid, unprocessed, blend of the two masters giving a feel for what the combined image will look like.
Stay tuned for the final processed image in a few days!
