Wonderful stuff Fred! 8)

I'm planning on visiting California, if not this year, next one for sure, and Yosemite is one of my MUST SEE places...

I definitely want to see also the Sequoia trees and visit the Grand Canyon while there... wink

Keep'em coming!

Guidescope choices

Posted By Ivan Gastaldo

Mark, I'm sure you'll get a lot of answers... (I hope)... wink

If you are "manually guiding", then getting/using a longer focal length scope than your imaging scope is a must... as you must catch the star movement before your imaging scope does...

If you are autoguiding, then your guidescope does not have to be longer than you imaging scope, actually, it will still be ok if you guiding scope is same or even a little shorter (in f/l) than your imaging scope, as software & cameras will handle this area quite well.

The problem with using a MAK as your guidescope is that the FOV is VERY limited, and your chances of finding a guide star in the area will be a lot tougher...

Of course, this is just my humble opinion... 8)
