After looking at several galaxies through Robert Armstrong's 20" obsession
I decided this was a good scope to own. Eventually, when I get a garage,
I would like to own something like that. So...
What is the limiting factor on how big a telescope one can fit into a
car (in my case this is a 98 Beetle)? Is it the ladder? The truss poles?
Is there a big difference in optical quality between f/4 and f/5?
At some of manufactures' web sites they mention 2" or 1.25" thickness
mirrors. What is the difference between these choices? Durability?
Does sweat pour down your face every time you need to move a thinner
mirror?
If this is OT then just point me in the right direction.
Thanks,
