RE: [APML] Help! Advice on collimating a C14

["Andrew Clegg" <andy@w4je.com>]

Hi Gene,

I had seen this site, and I agree, it's the best one. I have followed its
advice, but still no luck on getting good images. The degradation in my
images are consistent with the uncollimated images that are simulated on
this web site, only worse. I would kill to be able to see Saturn through my
C14 looking as good as the right-hand image at the top of this page! I will
be following everyone's suggestions and making sure everything is tightened
down on the 'scope the next time I attempt collimation.

Clear skies,
Andy

This is the best source on collimating SCTs:

http://perso.club-internet.fr/legault/collim.html

Just slewing from one side of the sky to the other is enough to lose
critical collimation for most mass market SCTs.

Gang,

This may not be the best place to ask this question, since everyone
seems to
use RCs or refractors, but I thought I'd ask anyway...

I have a C14 CGE, and I am having one &$%#^ of a time getting the thing
collimated.
