Hi all,

Well,I had some decent sky last night,other than the Moon being very bright and near my target that is!I wanted to shoot some deep RGB for the Ha I already had on this but I have learned my lesson more than once on shooting color with the Moon out.

I decided to shoot OIII on it,I was suprised by just how much OIII there is here,the signal was quite strong!
I also learned the OIII filter is not quite as effective as blocking moon glow as the Ha,I ended up with a minor gradient problem but it was not to hard to deal with.


Since I don't have a SII filter yet I made a synthetic green by adding 28% of my Ha data to the OIII to create this Bicolor.

I have another version in the works but I like how this one came out.What do you think?

This is 20x600s with an Astrodon 6nm Ha and 38x600s with an Astrodon OIII filter. Image is resized to 60% and trimmed just a bit around the edges.

Taken with my TMB115 at F7 and ST10xme.
1200gto guided with a remote guide head and efinder.

Thanks for having a look,

Jason

Really nice shot Jason. Great job with the processing. The added detail with the narrowband imaging always impresses me. Someday I'll have to swap my OSC for a monochrome with filters. I get so little time to image though. My dome is located at my cottage (much darker skies) which is exactly one hour from my house. I get up there maybe one day a week if the sky permits. What type of observatory do you have?
