Hello Alexander and Jason,
thanks a lot for your detailed descriptions. I now have a much better understanding of the physics behind it. Without your advise my frustrations about this seemingly impossible task seemed to have displaced my conviction for this hobby. I feel much better now
I will go ahead and procure a Cheshire. Are there many differences? I saw that the Celestron version is $20 more then the Skywatcher although both look identical.
Thanks again for your time,
Clear Skies!
