5-Position Filter Wheel Holder for Telescope Filter 2 Inch

The filter wheel interior is absolutely light tight that allow you to image without any reflections or stray light; It's construction is impermeable to light and thus ensures reflection free astrophotography
Please note: your focuser will require 22.5 mm of inward focusing distance from the normal focus position to compensate for the thickness of the filter wheel

-- 2" filter wheel - change your filter in seconds - space for up to 5
This 2" filter wheel lets you use up to 5 different filters and changes them within just a few seconds. Whether for astrophotography or visual observing - your filters are always ready to use. Use the filter wheel with UHC, OII, CLS or wide-band and narrow-band filters for visual observing, for example - which let you quickly and easily find the best filter when visually observing. You can also leave your filters mounted in the filter wheel, as they are optimally protected from dust and damage there.
Part List and Care/Storage:
Feel free to leave your 2" filters installed in the wheel during storage. To avoid excessive dust build up, attach the dust caps prior to storing, and use a foam-lined accessory case. The foam-lined box your Multiple Filter Wheel arrives in also acts as a convenient storage container.

Attaching an Eyepiece:
For visual use, you will need to attach the camera adapter and 2" eyepiece adapter to the Multiple Filter Wheel. To do this, thread the two adapters onto the back plate of the wheel assembly. Once the adapters are completely attached, unscrew the knurled thumbscrew until it is flush with the inside surface of the adapter and insert a 2" eyepiece. Secure the eyepiece by tightening the thumbscrew.
Attaching a Digital Imager:
If you are using a digital imager that features T-threads, you can attach it to the Multiple Filter Wheel. If your digital imager has a 1.25" nosepiece, remove it to expose the T-threads. Now simply thread the imager onto the camera adapter via a "M48x 0.75 (2" Filter) Female to M42* 0.75 T / T2 Male Thread Telescope Adapter" (Not Included), and then thread the adapter onto the rear plate of the filter wheel assembly. You can lock your camera or digital imager in a preferred position by using the camera adapter's locking ring. Once you have positioned your camera or imager, rotate the knurled locking ring counter clockwise until it locks the camera or imager into place.
Attaching a Camera:
The Multiple Filter Wheel can be extremely useful for astro-imaging with a camera body, be it a SLR camera, CCD, or CMOS device. To attach a SLR camera to the filter wheel, use the included camera adapter, an optional T-ring for your SLR model and a "M48x 0.75 (2" Filter) Female to M42* 0.75 T / T2 Male Thread Telescope Adapter" (Not Included). Attach the side of the camera adapter without the knurled lock ring to the rear plate of the wheel assembly by rotating it clockwise until tight. Now thread your SLR camera T-ring onto the exposed T threads.
