Here is my most recent capture.

I did not use a field flattener - which I should.

Hi,

What are the processing details?
The only negative comment on the picture is the green touch; perhaps lower the green curve of the the Histogram or do an averaged green removal with SCNR.

Otherwise the Picture is really nice; M33 is a difficult candidate  ;)

Hello,
Thanks for the feedback. I can't remember all the processing details, it's 21 10minute subs stacked with DSS and processed with Pixinsight. I did some aggressive noise reduction with ACDNR using masks with different settings for luminance and RGB components. I did use SCNR. It's interesting that the image does not look green at all on my computer. I use my macbook pro for processing and my guess is that different monitors render colors slightly differently.
I will however lower the green curve. Typically I only use the color calibration tool in pixinsight to fix the colors.
