RE: [APML] Another image processing challenge for snowy nights-M45

I must be a masochist because here's my attempt at enhancing Tom's shot:

My gut feeling is that the 800 speed film is too grainy and that sky fog was too pronounced to make an effective final shot.  I wonder what the results would have been like with two, 30-minute exposures using 400 speed film instead.  Hmmm...

Hi All!

 

If any of you would like to try another raw image, I have a 2 shot composite of M45 at 2048x1371 pixels.  The image size is 8Mb and you can download it at

Be sure to right click the above hyperlink and select Save Target As

 

 

This one is 2 30 minute exposures on Fuji Superia 800 Extra.  There is no processing done at all.  No levels, nothing.  I'd love to see what the pros can do to my image!

 

My result is at http://astrophotonut.tripod.com/m45.htm

 

Thanks!
