Filter Installation:
Partial disassembly of the filter wheel(please refer to the product image). You may wish to note the number designation of each installed filter for convenient reference during use. You may find it useful to leave one of the five threaded filter locations empty, providing an unfiltered option for viewing or imaging. If you are installing an individual filter or swapping one filter for another, you can avoid partial disassembly of the filter wheel. To install an individual filter, unthread the 1.25" nosepiece from the assembly to expose the internal filter tray. Rotate the tray so the desired filter location is shown. Install the 1.25" filter by placing it on the filter tray and rotating it clockwise with your fingertips. Astromania 1.25" filters feature a knurled rim which will prove helpful for this type of installation. Be careful not to touch the actual filter surface. Note: individual filter installation without disassembly may not be convenient for all users, especially those with large fingers!
Attaching the Filter Wheel to a Telescope:
1)Using the 1.25" nosepiece: If your telescope features a 1.25" focuser, adapter, or diagonal the easiest way to attach the Multiple Filter Wheel is by using the included 1.25" nosepiece. Thread the nosepiece onto the front plate of the wheel assembly. Now simply insert the nosepiece into your telescopes' 1.25" 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" nosepiece. Carefully attach the wheel to the T-threads by rotating the entire assembly clockwise until tight.
