Hello everyone,
Tomorrow I'll go to buy my telescope. It is a "collapsible" ("Flex Tube") dobsonian (200/1200), f/6, central obst.:46mm. I'm a bit scared of the collapsible structure (stability?)...should I be?
P.S. Do I need to buy a tool for telescope collimation? Some Youtube videos show a tool for that...
I'm glad to have found a forum interested in amateur astronomy, best wishes all
