ZWO Infrared IR Cut-Off Filter (31.7mm, 1.25'')

ZWO Infrared IR Cut-Off Filter (31.7mm, 1.25")£25.00

Luminance/Infrared cut-off filters are usually being used with web cameras, color CMOS and CCD cameras to produce better quality images, as these are quite sensitive to infrared (heat) radiation of light.

ZWO IR Cut Filter 2''

ZWO IR Cut Filter 2"£51.00

This ZWO 2″ IR/UV CUT-OFF filter is suitable for color cameras with AR protect window.

ZWO Duo-Band Dual Narrowband Filter 1.25''

ZWO Duo-Band Dual Narrowband Filter 1.25"£86.00

The ZWO Duo-Band Filter is a dual narrowband filter primarily aimed at complementing our range of colour ASI cameras and offers an economical entry into the world of narrowband imaging and can also offer a practical solution to imaging in light polluted urban areas.

ZWO CH4 Methane Band Pass 20nm Filter 1.25''

ZWO CH4 Methane Band Pass 20nm Filter 1.25"£91.00

CH4 (methan) filters are recommended for CCD or CMOS cameras that have good sensitivity in the IR part of the spectrum at around 890nm . i.e. our ZWO ASI185 and ASI224 would be a good match for this filter.

ZWO 1.25'' H-Alpha 7nm Narrowband Filter Mark II

ZWO 1.25" H-Alpha 7nm Narrowband Filter Mark II£134.00

Narrowband filters are used to create high contrast deep sky images of certain objects, mainly emission and diffuse nebulae (i.e. Veil Nebula, M42 Orion Nebula, North America Nebula, Horsehead Nebula) or planetary nebulae

ZWO 1.25'' OIII 7nm Narrowband Filter Mark II

ZWO 1.25" OIII 7nm Narrowband Filter Mark II£134.00

The ZWO OIII 7nm narrowband filter is designed for nebula observation allowing 7nm bandwidth of light centered on a wavelength of 500nm, which corresponds to OIII emission lines, blocking out all other light.

ZWO 1.25'' SII 7nm Narrowband Filter Mark II

ZWO 1.25" SII 7nm Narrowband Filter Mark II£134.00

The ZWO SII 7nm narrowband filter passes light at 672nm wavelength with a bandpass of 7nm which is designed for nebula observation and imaging. It is suitable for visual observation on most emission nebulae
