Thanks all for the kind words..
Jase - Thanks. Dramatic is what I was going for with Eta.. Especially the starless version... I really wanted to show off the extended nebulosity and all the delicate folds that extend out out of the frame.. The Ha RGB blends do give me quite a bit of trouble.. I have a lot of trouble getting the colour balance right with Ha RGB blends, however this will soon be a thing of the past.. I've just ordered my own Ha, SII and OIII filters and an FLI 2-5 filter wheel... Im giving up on RGB. Being colour blind makes it too difficult to get a good, realistic image. I'll move to narrowband imaging so that I can never be told my colours are wrong... My eyes respond a lot better to the extreme contrast in narrowband....
Mike - Thanks mate.. I think I got the horsehead right this time around... Last time was attrocious in comparison
haha Yea, Did the Vanderhaven.. Im a convert after that... Starless nebulae i and stretching wesome.. you can keep stretching and stretching the nebulosity out!
I'm a big fan, I just need to refine my method of star removal.. This process introduced a fair few strange artifacts which I was not happy about. Practise makes perfect I suppose
