ZWO EFW 8×1.25 Filter Wheel

ZWO EFW 8×1.25 Filter Wheel: Eight positions: LRGB and narrowband in one wheel

With eight positions for 1.25-inch filters, this EFW wheel covers the complete recording palette in a single housing: Luminance, Red, Green and Blue plus H-alpha, SII and OIII, with one more position left over. Never again have to swap filters halfway through a project.

The precise, quiet stepping motor from the Japanese NPM positions each filter exactly repeatable, and with only 10 mm distance between filter and sensor, the image remains free from vignetting, even with fast lenses such as f/4.

For the complete project

Anyone who shoots LRGB and the Hubble palette over a series of nights automatically switches between all channels within a shooting plan using this wheel. No image shift, no touching the settings.

The CNC-machined aluminum housing weighs 400 grams and is only 20 mm thick: hardly any impact on backfocus and balance.

Directly integrated

Power and control are provided via the included USB 2.0 cable; the wheel works directly with ASI cameras, ASIAIR, and software such as NINA. T2 screw adapters and mounting screws are included.

Suitable for single cameras with sensors up to 4/3 format in combination with 1.25-inch filters.
