Filter Installation: 

To install an individual filter, unthread the 1.25-inch nosepiece from the assembly to expose the internal filter tray. Rotate the tray so the desired filter location is shown. Install the 1.25-inch filter by placing it on the filter tray and rotating it clockwise with your fingertips. 

Attaching the Filter Wheel to a Telescope: 

1.Using the 1.25-inch nosepiece: If your telescope features a 1.25-inch focuser, adapter, or diagonal the easiest way to attach the Multiple Filter Wheel is by using the included 1.25-inch nosepiece. Thread the nosepiece onto the front plate of the wheel assembly. Now simply insert the nosepiece into your telescopes' 1.25-inch focuser or accessory and secure by tightening the thumbscrew. 

2.Using T-threads: Some telescopes feature focus adapters with exterior T-threads. If you are using such a telescope, you can attach the Multiple Filter Wheel directly to the T-threads without using the 1.25-inch nosepiece. Carefully attach the wheel to the T-threads by rotating the entire assembly clockwise until tight.
