Hey Brian...
Nice, deep, classic 'piggy-back' effort. M 42 seems a little burned out, but the diffuser way have contributed to this. The dynamic range of this area of the night sky is a challenge for film. Here's a single exposure of the region with more focal length (135mm) and a Median Filter blur similar to the process you described in your previous post. For a larger version, go here:

... let me know when you add some others here at usefilm.com !!!

Thanks Mav,
You could probably get alot more out of that slide the way it is..
Make a duplicate layer, desaturate, invert, stamp out the brighter stars in the inverted layer, gaussian blur to 25.0, overlay, set the opacity to 50% then flatten.
Brings out the faint background stuff.
This also works quite well with any image to bring out detail in the shadows....try it in PS.
Have fun,
Brian

Nice Job!
I had take a similar one like yours.
Please take a look.
My Barnard's Loop is very dim since I can only take for 10 mins exposure. Since cloud is coming.

Hi A Vonbeck,
Nope, I didnt leave anything out...this is a 50mm as you look through it at orion...slight cropping to get rid of the stack seams but thats about it.
I used Picture Window pro to stack the two together.
The only magnification I used was a rifle scope to center on polaris which has nothing to do with the magnification of the lens.
If you want to see the original scan of the diffused photo, I do have that, but the other slide got destroyed by a coffee spill.
Email me privatley @ power_windows4789@yahoo.com and Ill send it bye request.
There really wasnt that much noise or a grain problem sice it was 200spd, although it was scanned at 72 dpi so that gave me a little lack of detail.
Sandwiching two slides together will also decreas. the signal to noise ratio.
Thank you for the kind comments:)
Brian

This is a beautiful image, Brian. However, you forgot one very important piece of information in your description: what kind / size telescope did you use to obtain this image (6 inch reflector, 12 inch reflector?). I'm sure a 50mm Nikon lens must have been mounted to something to gain this much magnification, eh? The colors are splendid, but how many of the background stars constitute "noise"? I'd love to see this image unstacked. You definitely have talents in astrophotogrphy. Peace.
