Re: [APML] req. for comments on NA Nebula & Pelican area image

Hi Dick,

Beautiful image!  Well composed, focus is dead nuts on, no rotation, etc... 
only problem is that darn grain.  I have two suggestions:

- run it through neatImage or sgbnr to flatten out the grain
- add a luminance layer to increase your s/n ratio.  Shoot the same image 
with hypered tech pan and use that as your luminance layer, rob g has a 
fantastic article/tutorial on his site for this process.  If you go this 
route, you'll want to consider hydrogen alpha filtration.

email me off list if you'd like me to take a shot at neatImage'ing it... I 
have a 200mm luminance of that area, which wouldn't help you much, but I 
could composite it and forward you the results.

john
