This Quick Filter Changer is for 50 mm and 50.4 mm unmounted filters - low profile:
The TS - M48 Filter Quick Changer for 50 mm and 50,4 unmounted filters only has 10 mm of optical length (back focus).
With a male/female M48 thread connection, it is the shortest Filter Quick Changer for extreme solutions if you have nearly no space. The changer is made for D= 50.4 mm unmounted filters e.g. from Baader.
Advantages of the Quick Filter Changer in comparison with other systems:
♦ There is no limit to the number of different filters you can use
♦ It has a very very low profile
♦ Supplies you with the best possible field illumination
♦ The Quick Filter Changer needs less space than a filter wheel
♦ Any filters currently not in use can be stored protected from dew and dust. In classical filter drawers the filters are completely unprotected!
Note: There is a very short M48 female connection thread on the telescope side: The thread is very short - if your connection adapter 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 and you will not be able to move it.
