Orion 5525 2-Inch Multiple 4-Filter Wheel

When it comes to field illumination for visual observing or astrophotography, bigger definitely is better! Enter Orion's new 2" Multiple Filter Wheel, which allows convenient switching of up to four 2" filters for astro-imaging. Since many of today's larger format monochrome CCD imagers require 2" filters for larger field illumination, this affordable solution provides fast and easy transition between multiple filters. The versatile 2" Multiple Filter Wheel provides several attachment methods. T-threads on the telescope side allow for a direct connection to T-thread equipped focusers. If attaching the filter wheel to a 2" focuser, a 2" thread-on nosepiece is also included which allows maximum field illumination to the imaging camera. A removable T-thread ring on the camera side allows for direct attachment to imaging cameras. Compatible with all 2" Orion filters. The 2" multiple filter wheel is not equipped for visual use. This accessory is a must-have for monochrome imagers, who need to take separate exposures through LRGB filters to obtain a color composite. Light finger pressure is all you need to rotate the wheel until the selected filter clicks into place. The 2" Multiple 4-Filter Wheel also provides a convenient and secure way to store your imaging filters and help protect them from dust and dew. Filters can be easily installed or changed by removing the cover with the included hex key. Requires 22mm additional focus travel. Weighs just 14oz. One-year limited warranty.
