Thanks Mike. I was happy with it. Jase gave me a good tip that this object is strongest in O111 much like Vela SNR is.

Probably needs more data to clear out the artifacts in the back ground.

This object is on my list to do with the RC. I might have to take a look at it with the OIII blended with blue, Ha blended with red, and green. I am keen to see more data on the image you have here.

More data is always good but sometimes hard to get. I have now moved to a fairly dark sky location close outside Sydney and will be building an observatory in the new year. I have a Paramount ME waiting and intend to out 2 piers in so I can get twice as much data each imaging session. That will help.

I have about 6 hours of LRGB data from earlier this year I can add.

I used deconvolution to the point where the stars were starting to get whacked. I had to repair a couple of the bigger stars. So there is a point of diminishing returns on that. The better the signal in the first place the harder you can push it. I did some slight noise control processing so perhaps the extra decon took it back to where it was before that but it was a tad noisy without it.

PS: Where did you get clear skies? I'll have to come and plonk my rig next to yours next time you image.

My site runs reverse to Sydney weather as its on the western side of the Great Dividing Range. Its gone back to that pattern. For about a year it was the reverse where Sydney was clear and it was cloudy. Fortunately it seems to have gone back to the normal pattern.

Bicolour does work well on nebs. It gives you whitish stars which aren't too bad.

Yes it came out well there. I guess that's the 180mm fluorite showing its stuff.

Its an intriguing object, quite dim in LRGB but strongest in O111 and next strongest in Ha. Same as Vela SNR and I presume other similar type nebs. I should check out Eta C in O111 to see what that looks like or The Rosette.
