Size doesn't matter

CC's effectiveness is dependent on magnification I think. with no CC my f4 scopes show a lot of coma in the outer field with my 32mm plossl but almost none with my 15mm plossl. with the CC there's almost none anywhere with any eyepiece.

I do agree also that coma corrector + heavy eyepiece + thin ota wall = affect on collimation accuracy. you just have to either accept it or strenghten your ota wall.

3kg can't be good for balance either .

true but it doesn't affect my scopes really. I can generally go from 26mm Nagler and CC to BGO and CC with no issues. another often ignore benefit of a faster scope!
