RE: [APML] Converting CCD Workflow to Film?

[John Mirtle <spampit@shaw.ca>]

Thomas,
	To get sharp stars *and* comets with film, have you considered a
Schmidt? At f1.5 you can bag almost any comet before it has time to move.
With the roll film adapter the camera isn't that hard to use and with many
people switching to DSLR or CCD cameras, Schmidts pop up from time to time
on Astromart at a good price. I still firmly believe that they are the best
hunting rifle for comets and don't require fancy programming of drive motors
or anything else! I plan to keep my Schmidt for as many years as they make
film, just for this purpose.

Back in May with NEAT, I simply used the comet as the guidestar.

Here's a NEAT with the behive...

The combo for this was: G11 (not gemeni), FSQ106, 200mm FL guidescope
(camera lens),
ST7E using the big chip for guiding, CCDOps for guide software.

35mm Provia 400 was ued.  (this was before the pentax67 was aquired.)

It seemed to work, but maybe wasnt ideal. The CCD guys got way better
results.

Clearly, with M45 this is tougher if you want to get M45 nebulosity intact.
I dunno how one would do that without compositing.

I now have a AP900 (as of about 1 month ago) and the "comet guiding"
feature is news to me.. I'll have to figure that out!
