C80ED tube ring size?

[beamer3.6m]

i have a c80ed and want to add standard tube rings instead of the clamshell it comes with.

will the skywatcher 90mm rings fit without modification?

cheers

I think it's 90mm rather than the 100mm that the Sywatcher ED80 Pro's are. Celestron seems to have opted for a slimmer tube. I've not actually seen one though so it's probably wise to double check this.

Steve told me the size the other day, I am sure it was something like 92mm, I asume the stanard skywacher 90mm rings will work OK
