Televue PTR-4201
A long-shot, but if anyone with a Televue PTR-4201 T-ring adapter for the 4x 2" Televue powermate can measure the total height of it, and the height of the threaded portion, would be greatly appreciated!
Can't find the measurement anywhere! If no-one has one, I will give Televue a call tomorrow, but wanted to place an order for some extension rings today...and so if someone has the measurement would be greatly appreciated!
TIA and clear skies to all!
