This kit includes all the parts of the Baader UFC system we selected for the Nikon Z cameras:
Baader UFC (Universal Filter Changer) with S70 dovetail (2459110)
Baader Wide-T ring for Nikon Z with S52/T2 (2408335)
Baader UFC camera adapter S52 for Wide-T rings (2459119)
Baader UFC filter slider for 50,8mm filters with cell (2459119)
Baader UFC extension 15mm with S70 connection (2459112)
By connecting this set to the Nikon Z cameras, the camera sensor will be at 55mm from the front thread and this is requested by many telescopes or correctors. But, in respect to a standard DSLR camera, you will also be able to insert the 2" filter holder (and a 2" filter) in front of the sensor. 2" filter is not included in this set, you can choose the one that better fits your needs.
