This image is 11.7 hours worth of data taken during the last new moon cycle. There is still some noise but overall I am quite happy with it now.

Comments welcome.
Excellent image Paul, I knew you would be happy with the ME but I am thrilled to hear you are enjoying it. The results are fantastic.

Kindest Regards,

Thanks all for the comments and observations.

Marcus, Mike and Greg; the main problem with the image is that the signal is not high enough to get over the noise related issues. Even 15 minute subs in RG and 20 min in L and B was not enough to get over the problem. I had to use several runs of guassian smoothing to get around the errant noise. I will take a look at this again sometime as I tend to agree with Mike's comments in that it looks a little flat. The smoothing sort of killed the photographic quality some what.

I was also careful not to over process the data and did a lot of selective sharpening to avoid this issue. It might look a little hard but that might be the noise just creeping in a little to give that edgy appearance.

I don't think there is now enough time on this side of the meridian to improve the level of signal and I tend to agree with Marcus that doubling the amount of exposure will be more effective than only getting another 5 hours.

Thanks once again for all the feedback and I will soon have another reprocess of this fascinating object.

Much better. The core is smoother and more details pop up now. Also the colours on the outerneb and the barnard loop are more natural.

Oh yeah baby that's nice.

Looks more balanced and smoother and nice deep saturated colours yet very luminous.

Terrific.

Greg.
