Ajay,
It doesn't look like there is a group.io for CGX-L owners.? I own one and would be willing to join the group and/or try to answer questions you might have.? Celestron hosts a customer blog and a good FAQ which I have used in the past but I have also relied upon their technical support team and the retailer from whom I purchased the mount.
