Re: April talk


 

Joe,

Probably one of the best websites that explains collimation is Therry Legault's site:



You can do a google search and find many more.

It's a bit intimidating at first, but it's relatively easy.

One thing you definitely want is a set of Bob's Nobs, or the equivalent from scopestuff:



These are nylon thumbscrews that replace the factory screws. My Meade requires a hex wrench to adjust them; the Celestrons may require a screwdriver. Nothing's worse than hearing the "tink" when you drop a hex wrench on your corrector!!!!

Ted,
The title of the April talk I'm giving will be "Everything you always
wanted to know about Copernicus(but were afraid to ask)" if you want
to update the web page.
I have been on call continuously for several weeks and have not been
able to get the scope out for fear I would be called in and have to
put it all away fast.The few times I have had it out the stars don't
seem as crisp as I would expect. It's either 1 poor seeing 2 poor
colimation 3 something about the scope. I suspect a severe
collimation problem. Need to find a nightwatch where I can see what
you guys think.Any suggestions for SCT collimation would be welcome.
