M1 "The Crab Nebula" (HST palette) reprocessed

Recommended Posts

Hi All

I posted an image of M1 in HST palette a few days ago, but the image was very noisy and overprocessed so I have had a go at reprocessing it, I think this looks much cleaner and more detailed but would be interested to hear peoples comments. This is an extreme crop of the full widefield image as it was taken with my TMB 115 and H36 camera. The full widefield shot can be seen on my website http://www.imagingtheheavens.co.uk in the nebulae section of the image gallery along with the original versions for comparison, just as a reminder the details are as follows

TMB 115 f7

Paramount ME

Starlight Xpress H36

9x10 minutes Ha

12x10 minutes OIII

5x10 minutes SII (subject was too low in the sky for more subframes)

All exposures were unguided

Colour combined in Maxim DL with 1:1:1 weighting for RGB

Thanks for looking (again)

Best wishes

Gordon

Hi Ray

Thanks for the comments, I was a bit less aggressive with the curves in the early stages and used a combination of the noise reduction routine in Noels Tools in Photoshop and and some very slight reverse curves. There is still a tiny bit of noise evident but to remove this would mean the main subject would suffer

Best wishes

Gordon
