NGC6992_Bi-Colour_9-7-2018

            I learnt a lot from processing my last image of the Western Veil and this one took me a fraction of the time to finish, I also created a "Work Flow" pdf for future reference. This took me 3 nights to obtain 5h hours of data due to mainly human error.
1. I forgot to plug in the cooler on the camera.
2. Found I had altered the rotation when putting the scope back on the mount. 
Once again I combine my processed Ha and Oiii to create a Ha/Oiii luminance Layer. I added my Ha as a layer to my Oiii image and changed the "Blending Mode" to "Lighten"

Object Description:-

The whole object (of which this is only part) covers an area of equivalent to 6 times the Dia of the Full Moon. This object is very rich in Oxygen (Oiii)
