TS - M48 Filter Quick Changer for 50mm and 50,4 unmounted filters - only 10mm optical length
- with male/female M48 thread connection. The shortest Filter Quick Changer for extreme solutions if you have nearly no space - the changer is made for D=50,4mm unmounted filters e.g. from Baader.
Advantages of the Filter Quick Changer:
- very very low profile
- this also results in best possible field illumination
- the filter quick changer needs less space than e.g. a filter wheel
Very short M48 female connection thread on the telescope site: The thread is very short - if your connection adaptor has a longer M48 thread, you will need M48 fine tuning rings. If the connection thread goes too deep into the filter changer, the drawer will be blocked, you cannot move it.
