8" GOTO Dobsonian - Collapsible vs Solid tube
Hello everyone, this is my first post. I'm a newbie to astronomy and my head hurts with the variety of choices on offer for my first telescope.
An 8" Dobsonian seems to come highly recommended as a good beginner platform so I have been researching the options. I really like the idea of a goto mount so that I don't have to keep nudging the scope to keep the image centred.
I am comparing features between the Orion SkyQuest XT8G and the Sky-Watcher Black Diamond collapsible GOTO 8-inch Dobsonian.
I am a little concerned about the collapsible design of the SW. It looks like there is more opportunity for collimation to be an issue. Should I be concerned about getting a collapsible vs solid tube?
Are there any significant differences between the goto systems I should now about?
Cheers
Graeme
