ITSY BITSY CHIP, large FOV?

Well, here is a test I did with my small chip Orion Starshoot and a 50mm SLR lense.
(about a couple of weeks ago)

If any of you have any pointers, I would really appreciate it.
I had the lense stopped way down, to control star bloating.

I shot the M8 & M20 area, 12x5min, aligned & stacked with Nebulosity, processed with Photoshop CS2. (I was not happy with the colors achieved, so switched to Grayscale)


Clear skies! 8)
(talk about squeezing the most out of this camera!)

I say, that is a huge FOV! Quite a bit of nebulosity around that area that you can see. Don't consider my thoughts too deeply as I am not real versed, but I wonder if a minus violet/uv cut type filter on front of cameral lens would control bloat to allow for more aperture or even make stars sharper at current aperture. How about a Halpha filter? that would surely tighten stars.

I wonder if that chip is so small that stopping down your lens really helps that much. Most are pretty good in the middle. Might depend on the lens manufacturer. (?) That might be an interesting comparison to try several shots using different f-stops/shutter speeds to get equal exposures. What is the chip size and pixel size with that lens?

(This is another thing in my queue to try. I have an adapter for various Canon lenses and the SBIG camera, but haven't gotten that far yet.)
