m82, 02. February 2005. Same capture as image below, just different processing again!! This time, Stéphane from France stepped in with much advanced processing using IRIS. The processing details (in French!) are in m82_20050202d.txt . I have to investigate what this means....

Merci Stéphane!, where does it end? Stéphane's C8 web page is at http://astrosurf.com/c8/

m82, 02. February 2005. Same capture as image below, just different processing again!! This time I used algorithm 9 (Variable Gradients) in AviRaw.

Better?

m82, 02. February 2005. Same capture as image below, just different processing. I found that the processing below was a bit too pig-like, so I tried another approach. I used AVIRaw to split the AVI into separate channel AVI's using GB and 07-PatternRecognition debayer option. I then processed each channel separately, reassembled them in Photoshop CS and put the BW luminosity layer on top.

Better?
