ZWO EFW 8 x 1.25" / 31,7 mm

The ZWO EFW 8x1.25" filter wheel is a revolutionary device that allows for the easy installation of up to eight 1.25" or 31 mm filters. With this filter wheel, you can conveniently place a set of LRGB filters on the carousel while still having space for the Hα, S-II, and O-III filters from the HST palette.

Controlling the filter wheel is a breeze with its software, which is compatible with the ASCOM controller. You can connect the wheel to your computer or directly to the USB outputs on your camera using a USB 2.0 cable. The filter wheel's sleek black housing is crafted using CNC technology and the highest quality aluminum alloy found in the aviation industry. It features a filter wheel drive powered by a stepper motor from the renowned Japanese company NPM.

One of the standout features of this product is the minimal distance between the filter and the camera matrix, which effectively eliminates vignetting, even when using high-intensity telescopes. For example, when using the ASI 1600 camera, vignetting is avoided at f/5 for 1.25" filters and at f/2 for 31 mm filters.

Before purchasing the ZWO EFW 8x1.25" filter wheel, it is important to verify the required back focus of your camera to ensure compatibility.
