Description

I have had this data for a long time, but only bothered to process the Ha side of the mosaic, because there was so little OIII in the final stack - it was barely visible. I think that maybe due to the fact that this nebula has not got a lot of OIII in it anyway.

So, I decided to create a blended green version of the data through Pixelmaths, giving rise to this slightly unusual tone. On pane 1 there 8 subs at 20 minutes long each in Ha, and 10 subs in OIII at 20 minutes long also. In pane 2 there was 12 subs at 20 minutes long each in Ha and only 8 subs in OIII at 20 minutes long each. Total integration time was: 7 hours 40 minutes.

I did try a HOO version, which turned out OK... but I am not sure whether to post it. Thanks...
