Michael, thank you.
Valid point. I suspect most of the additional weight will be on the rear cell of the C14 which is pretty thick and very rigid. I don’t think as much weight and potential distortion on the front cell. I am off to the International Astronomy Show in a few weeks so I’ll speak to people there. The only rings I’ve seen for the C14 are over £1000 which seems crazy, and I do wonder if the thin skin of the scope is better or worse in terms of stability and applying forces through/over the C14.
