1)Collimation. I hear the 10’s need this regularly, especially after every car trip?
shouldnt be worse than anything else? the faster you go the harder it gets to get it right, F4 can be not a lot of fun, F8 easy
2)Dew problems. More of a problem with a 10”?
here EVERYTHING has a dew problem
3)Cooling down period takes longer?
bigger bit of glass takes longer yes but most 10's have a fan , if not get one
5). Do I have to carefully pick my nights when I view planets?.
I can only say when a 4.5" sees a planet as a blurry spot the 8" see's a planet so i would assume ,and its what I hear, a bigger scope is less effected than a smaller one as it gets more light to your eye
Maybe someone here has a 10 they could lend Suzy to try?
Buy what makes you happy! (no that does not mean new shoes instead)
