Lagoon (M8), Trifid (M20) and IC4685

[Buzzard75]

It's been a while since I have been able to get out and do some imaging. M8 and M20 have been on my list for a very long time, almost since I got started in this hobby over four years ago. My skills have definitely come a long way in that time. I decided to try a bit of an experiment and combine some narrowband data with broadband. I've done Ha combined with red before, but I'd never done OIII combined with green or blue. The process is obviously similar, but the Pixel Math variables in Pixinsight are slightly different. The humidity was extremely high that night and the seeing was poor. I'm still happy with the overall result.

Great image, the Trifid is one of my favourites unfortunately I can't see it from my house due to trees and nearby houses, maybe one day I'll manage to get somewhere to image/observe it.
