Can't focus with GSO Newtonian
Hi,
Took delivery of my GS-530 (150x1000mm) yesterday, and after a herculean effort to get the end cap off (it was stuck in there good!) I took it out for a spin.
Immediately I found that I couldn't rack the focuser out far enough to any of my eyepieces, from 32-12 to focus. So I checked my collimation using a laser collimator, and it looked good, and then I verified I can focus by manually pulling the eyepiece out slightly.
So I pulled converted one of my into a barlows into an extender tube, and got focus that way, and enjoyed the rest of the night. But is this normal? I would have expected to be able to focus without any modifications.
Cheers,
Steve
