ZWO Electronic Filter Wheel Enhanced Version: 7 x 2" Filters

The ZWO Electronic Filter Wheel (EFW) 7 x 2" is an advanced upgrade from its predecessor, the 5 x 2" model. This enhanced version is designed to house seven filters, each measuring 2 inches or approximately 50.4 ± 0.5 mm in diameter, making it ideal for astrophotographers and astronomers seeking versatility and precision.

Effortless Control and Connectivity

Managing your filter wheel is seamless with the ASCOM-compatible software. Simply connect it to your computer or directly to your camera's USB ports using the included USB 2.0 cable. The filter wheel boasts a sleek, black casing crafted from high-quality aluminum alloy, commonly used in aviation, and precision-made using CNC technology. At its core is a reliable stepper motor from the esteemed Japanese manufacturer, NPM.

Optimal Performance for High-Intensity Telescopes

A key feature of this filter wheel is its minimal distance between the filter and the camera sensor, which prevents vignetting even when using high-intensity telescopes. This ensures superior image quality and clarity in your astrophotography endeavors.

Before purchasing, please verify the required back focus length of your camera. Detailed connection examples are available on the manufacturer's website: Best Back Focus Length Solutions.
