Astromania 1.25" 5-Position Telescope Filter Wheel with LRGB Filters - Premium Astronomy Accessory for Deep Sky Imaging & Astrophotography

- This 1.25" filter wheel lets you use up to 5 different filters and change them within a couple of seconds -your filters are always remain ready to use, whether for photography or visual observing. Use the filter wheel with UHC, OII, CLS and other filters, for example - this will let you quickly and easily find the best filter when visually observing. - When using the Multiple Filter Wheel, you may find it useful to leave one of the five threaded filter locations empty, as it provides an unfiltered option for viewing or imaging. Keep in mind that use of the Multiple Filter Wheel requires 20mm of inward focus travel. This will not be a problem for most telescope designs, but could be a problem for Newtonian reflectors. Using Tips : 1. Note the reference number of each filter during installation. 2. Rotate the knurled wheel until the desired number is displayed in the small notch in the filter wheel housing. 3. The filter wheel comes with 3 set of bearings (3 metal balls, 3 springs and 3 brass bushing), which is the most suitable for the rotation of filter tray. Attaching an Eyepiece For visual use, you will need to attach the 1.25" eyepiece adapter to the Multiple Filter Wheel. To do this, thread the 1.25" adapter onto the back plate of the wheel assembly. Once the adapter is completely attached, unscrew the knurled thumbscrew until it is flush with the inside surface of the adapter and insert a 1.25" 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 directly 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, 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 and an optional T-ring for your SLR model. 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. Note: The filter wheel arrives with the camera adapter preinstalled. Attaching the Filter Wheel to a Telescope 1.25" nosepiece: If the telescope features a 1.25” focuser, adapter, or diagonal, using the 1.25" nosepiece to attach the Multiple Filter Wheel. Thread the nosepiece onto the front plate of the wheel assembly. Simply insert the nosepiece into your telescopes' 1.25" focuser or accessory. 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 clockwise to the T-threads without using the 1.25" nosepiece. Attention No Need to Disassemble - External Correctly 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. SPECIFICATION: The filter wheel can be attached to your focuser either by the supplied 1.25" nosepiece adaptor Available for Imaging devices: 1.25" Eyepiece, Attaching a digital imager, CMOS Electronic Digital Eyepiece and Camera Type: Manual Color: Black
