This high performance CCD filter transmits only the Hydogen Beta emission line, and therefore is useful for greatly increasing the contrast of objects that glow in the corresponding region of the spectrum, for example the Horsehead, Cocoon and California nebulae.

OVL Hydrogen Beta Filters

ONLY £28.00  -  £39.99

The O-III narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm) emitted by diffuse, planetary and extremely faint nebulae.

OVL Oxygen III Narrowband Filter

ONLY £39.99  -  £59.99

The Astronomik H-beta is a filter for visual observation, in particular with instruments of larger aperture. Available in 1.25" and 2" fits.

Astronomik H-Beta Filters

ONLY £73.00  -  £129.99

This high quality UHC filter is a narrowband nebula filter for enhancing globular and planetary deep sky objects. It blocks out a certain band of light to enhance contrast and detail on deep sky objects.

Antares UHC Narrowband Nebula Filter 1.25''

ONLY £74.99

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'' H-Alpha 7nm Narrowband Filter

ONLY £115.00   £92.00

Baader H-Alpha 7nm CCD Narrowband Filters

ONLY £103.00  -  £165.00

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 (i.e. M27 Dumbbell nebula, M57 Ring Nebula, Helix Nebula), just to mention few of well known nebulosities.

ZWO 31mm H-Alpha 7nm Narrowband Unmounted Filter

ONLY £133.00   £106.00

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'' OIII 7nm Narrowband Filter

ONLY £115.00

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

ZWO 1.25'' SII 7nm Narrowband Filter

ONLY £115.00

Available in 1 ", 2", H-alpha / O III and S II are designed especially for the delicate requirements of extremely fast astrograph optics, in particular Hyperstar and Celestron's New RASA.
