Description

Well........... the weather has been relentlessly terrible so have been taking a look at my previous attempt at this subject. I had in the back of my mind to play around with the data when I first imaged this but elected to use the data as was out of camera. This version is an extraction of Ha and Oiii from the L-eNhance data to form an HOO image.

This took a lot of tinkering and playing around with as I noticed that the stars were becoming very large and exceptionally blue. I tried StarNet++ but the result wasn't great, it left behind the fuzzy halos from the stars which, as is now I don't know how to process out - the healing tool was doing a pretty bad job (probably inability to use it). Started again using many star masks and even working on individual stars.

I must say, yes maybe I am a little bit of a hypocrite as I was never a fan of the false colour images but it really does give licence to experiment Anyway this was a lot fun playing around with the data and learning different ways of doing things. I must say, I feel as though the argument for going down the mono camera route seems to lessen and lessen with better cameras and very good bi, tri and quad filters giving great flexibility.

Anyway I hope you like this image and thanks for reading
