[APML] planetary photography

["Mark Park" <mark_park@hotmail.com>]

I can't seem to get good images of the planets.

My first question is how do you focus for eyepiece projection.  Can I setup 
the projection, move to a star and knife edge?  I know I can't knife edge on 
the planet since it is not a point source.  Planets are much closer than 
stars (to understate the obvious), but are they at the same focal point for 
the eyepiece projection?

Second question...  How much should I crank up the magnafication from the 
projection (ie distance of camera from eyepiece)?  from the eyepiece (ie 
24mm vs 8mm)?  Is one method better than the other?


Thanks in advance...
