Mike,

	Here is the full resolution of the NGC2067 region with the Schmidt. Full 
resolution is from a 4000 dpi scan of the TP negatives. The CCD version 
has 2.5 times the magnification (5" f/6 vs. 8" f/1.5). I did not attempt 
to match exactly the size and rotation of the CCD version as the 
resolution comparison is obvious.

You can see the Herbig Haro objects in the film version which I think is 
pretty good. These are the reddish objects near the brighter yellow star 
near the lower right corner.

Note that the 2.5X focal length difference will make a big difference in 
resolution. This significantly handicaps the resolution of the film 
image. On the other hand the field size of the film image is much much 
larger.
