First Bi-colour NB - I'm sorry

After getting some nice data on the keyhole neb in Ha on friday (http://www.iceinspace.com.au/forum/s...=103466&page=2), I decided to take some OIII data on Monday and try my hand at creating a bi-colour image from my NB filters I've never done this before so I wasn't expecting to post up this image. However once I finished editing, I was quite pleased with how it turned out for only ~10min worth of processing so - here it is

And I'm sorry because I know this has been imaged to death, but I'm just really happy its all starting to come together Details of my setup and Ha imaging are in the link above, OIII had 6*600sec subs + 15 darks (Ha had no calibration applied). Seeing was horrible for both sets of data, temps at midnight were around 26C. OIII was mapped to G, Ha to R, and B channel was made from a 50/50 blend of OIII and Ha. I didn't focus the OIII properly (Since I used my Bahtinov mask with the Ha and didn't change it to match OIII - all part of the learning curve I suppose).

I love astronomy

Thanks John yea I noticed them too, it didn’t seem to be there in the Ha subs so it's a bit odd. I'll have a look see at my data when I'm home and see why it occurred. Could just be the result of poor collimation
