Interchange your filters and protect them from dew with this precision built, low profile and easy to use filter wheel for visual and astrophotography use.  Dust caps are included.
 
Easily change up to 5 filters with the 2" filter wheel.  Filter positions are numbered from 1 to 5 for easy identification.
 
The accessory side has both T-2 and M48 threads.
 
Please note:  While this filter wheel is low profile, your focuser will require approximately 20mm of inward travel to compensate for the thickness of this filter wheel.
