Rosette Nebula - with bit of colour now :)

[James]

I've added a little more data to my earlier Ha image of the Rosette  - it's helped a bit with the noise but I've put more effort into getting OIII for this as well. I've put the Ha and OIII data together as an Ha OIII OIII image - I tried some blending (Red Ha, OIII Green 40% Ha 60%, Blue  OIII) but didn't like the colours I was getting... but I may go back to that as I don't fancy my chances at having enough time this winter to get SII for this object... especially as I think I want to make a mosaic of this one - the Cone Nebula is just off to the left...

Details:

21x  Ha 5 min subs

25x OIII 5 min subs

Guided, captured, scope control through The SkyX Pro and EQDIR

Please click on the picture and wait, a much better image will load!

Next task - to see what upping the gain on the ASI1600mm-cool will do
