A McEwan Posted January 1 Share Posted January 1 Hi. I have a quick question about the item pictured: Baader 2" Clicklock 47mm Extension. So, in the picture it looks like a 2" Clicklock adapter attached to an extension tube, which inserts into a 2" diagonal or visual back, etc. What I need to know, is how does the Clicklock section attach to the extension tube? And, if detatched, does the Clicklock section then have a T-2 thread to enable it to be attached to other things? Thanks for any light shed on this, Ant 1 Link to comment Share on other sites More sharing options...
Don Pensack Posted January 1 Share Posted January 1 (edited) See: https://www.baader-planetarium.com/en/baader-2"-clicklock-eyepiece-clamps.html For sure it is not a T-Thread under the adapter. The I.D. of the 2" adapter is 48mm for 2" filters. The I.D. of the upper section is 50.8mm+ a bit. T-Thread is only 42mm, so it would make no sense to make this adapter with a 42mm choke point in the middle. Ergo, the thread in the middle, where the Click lock connects is probably larger than 50.8mm. The drawing implies at least 50.8mm.
