Well I've got the fever and looking to upsize my rig very soon. I've got my eye on a solid tube GSO 12" dob. Read a few reviews online and they were all positive but I have a few questions for any members with one of these scopes.

Does the primary mirror have a centre spot for collimation?

How well does it hold collimation?

What is the length of the OTA? Height/diameter of the base?

I know they are impressive on DSO's, but what are views of the planets like in good seeing?

This may be a stupid question but would it be easy to attach a larger finderscope to the OTA, or will this upset the balance too much?

Apologies for all the questions, I want to be 100% sure about this scope before I drop the cash on it. Also very interested to hear your thoughts or criticisms on this particular scope.

Cheers
Wade
