Product Questions and Answers

No questions yet. Be the first to ask a question about this product - it will be answered by other customers or an Admin.


Modern cameras are usually characterised by extremely short optical heights, in order to be able to be mounted on various telescope constructions. The old T-2 standard with 5 mm thread depth is a hindrance to this. To take care of this new development, all new Baader T-2 and M48 parts are delivered with the new 3 mm standard.
