Description

Description: Not a revision so much as trying this again with new filters to see if i could get rid of the horrible halos you can see in the original image. For this revision, I mixed in RGB with the Oiii to get more colourful stars. While I did add in some Ha, i definitely need more data in order to bring out the red Ha - not that there is much.
I'm not that experienced mixing RGB with NB so i used the NBRGBC script in Pixinsight to put it all together in a linear state and then used curves and some noise reduction to produce the final image. Let me know if there is a better way to do it.
