The ZWO EFW motorised filter wheel with seven 2" filter positions allows you to change filters electronically via a computer, ZWO ASIAir or ToupTek Stellavita. An excellent match even for cameras with full-frame sensors.
The filter wheel features T2 threads on both sides, providing a simple and secure connection between the telescope and the camera. It also offers screw-on mounting options for the manufacturer's cooled cameras, allowing the filter wheel to be positioned closer to the sensor to help minimise vignetting. The unit connects to a computer via a USB 2.0 port and, once the ASCOM driver is installed, can be easily controlled using any compatible software.
The ZWO EFW motorised filter wheel is housed in a high-quality aluminium body, measuring just 20 mm in thickness and weighing 720 grams. Thanks to its slim design, it can be positioned remarkably close to the camera sensor, eliminating concerns about vignetting even with fast telescopes.
The updated filter wheel features a USB-C connector and additional shielding against stray light.
