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.

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.

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, planetary nebulae and supernova remnants

The EQ2 Equatorial Mount is suited to both beginners and experienced astronomers. It offers very good stability and the tall, fully adjustable aluminium tripod with large accessory tray is a real plus.

The NEW ZWO ASI120MM MINI or ASI120MINI is an excellent choice for an affordable planetary and deep sky camera for those who have just started in astro photography.
