Thanks Mike - I know my image is not going to be as good as Marcus' considering his skill level, not to mention his location, gear, etc., etc., but I have got a rather large competitive streak which means I'll keep working at this until I get damn close to his! I'm currently driving my wife mad - "I thought you'd processed that picture already?" I heard her mutter as she walked past me at the 'puter last night.... It's the same competitive streak that made me think I could get past big Islander wingers of the opposition when I was playing Golden Oldies Rugby... and by God I did some of the time!!
Anyway back to the topic at hand. I've been getting some valuable advice from Ivo Jager regarding my missing yellow stars and so went back to look at my raw data. While I was carefully looking at the central region of the Trifid I noticed that the central stars seemed wonky. I thought that to add to my problems I had a mis-stack issue with DSS. "Great", I thought, "that's all I need!". However on more careful investigation it seems that rather than there being two stars, there are actually two bigguns and two small ones close together. As soon as I try to bring the white point up I lose the definition of these so that's something else I'll need to consider in my repro...
I've attached two images, firstly the central portion of a semi-processed piece of my data together with the Hubble equivalent. It's gratifying to get this sort of detail from the middle of a big city - it means that my gear is all working as it should and that collimation is pretty much spot on.
Right, back to processing....
Cheers,
