What can a CG-4 mount take?

[Bart]

Hello All,

I currently have a Celestron 150mm Newt on a CG-4 Eq Mount. Can this mount take a larger OTA I was wondereing, if and when I decided to increase aperture? Thanks

I think 6" is about it's limit to be honest for short tube scopes. 4" for longer tube ones. Perhaps a little more if yours has the 1.5" / 1.75" steel tube tripod legs but not a lot.

I've seen 8" newtonians and 4.7" F/8 refractors on them and they are too much for the mounts.

Thanks John, So its probably a Dob, or a lot of money if I was to keep to a GEM with a bigger aperture

I think so - the dob is by far the lowest cost route to large aperture.
