Orion Optics VX12 or CT12 owners

[Captain Scarlet]

Could anyone who owns a recent OO 12” newt, please do me a favour?

Could you measure the distance (in the along-tube direction) between the primary cell attachment bolts (centre- point) and the rear face of the mirror. If you can tell how much rearward movement of the mirror you have, so much the better. It’s the minimum such distance I’m looking to discover.

I’m looking to replace my old corroded thread-worn Skywatcher rear cell (containing an OO 300mm mirror) with an Orion Optics one. I have an OO 200mm cell and like it very much. But before I go ahead and place the order I want to know what that distance is, as I don’t have infinite OTA length to play with. See my terrible drawing below for an illustration of what I’m after.

(And yes I have asked them, but I want the answer confirmed by a user).

Thanks, Magnus
