Please Help Me Show me the way
« on: 2015 September 25 11:09:46 »
Hello Everyone

Finished processing Cirrus East and NW Nebula image. 18 5 minute images BPP then realigned Red and blue to Green and processed but I can not seem to get any real sharpness in the nebula seems to always be fuzzy in the end. Please make some suggestions. In dropbox is final image xisf format as well as original image before any post processing but has been BPP. PLEASE help and here is a quick jpg of the final image.


Here is final image in xisf format:https://www.dropbox.com/s/x89z8c4vwh7h5mv/Cirrus%20East%20and%20NW%20xisf.xisf?dl=0
Here is original just after BPP:https://www.dropbox.com/s/4ub60dxld7uwi9z/light-BINNING_1.xisf?dl=0

i think maybe you applied too much noise reduction and/or did it without a mask to protect the brighter areas?

other than that it looks pretty good.

Hi Rob

Thanks for the reply.  Linear state did TGVDeNoise and MMT with a mask Protecting the brighter areas. Maybe either the mask was not too good or was a little heavy handed with settings inn both noise reduction processes you can look at BPP image and try yourself as well

OK - i find getting TGVDenoise right is hard sometimes. you can also use multi scale median transform thru a mask to sharpen up the brighter areas, if you boost the first 2-3 scales by 0.09 to 0.11 or so. sometimes boosting the first scale just enhances noise though so in that case skip pixel scale 1.

Hello Rob


I tiried less Nosie reduction in the linear state and then continue to process. Now looks better but would love to see hat someone else can do with the data (image). Keep up the comments it helps.
