    ZWO 36mm Ha SII OIII 7nm set MKII

    These are the latest MkII filters from ZWO, supplied with enhanced anti-reflection coatings. These are unmounted filters for the widest possible aperture for larger sensored cameras. Please note: you will need a filterwheel capable of taking unmounted filters in order to use this set. We recommend the ZWO Electronik filter wheel, 7-pos. 36mm.

    Narrowband filter sets 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. Narrowband filter sets are sometimes used instead of LRGB filter sets and sometimes in combination with them...

    Some amateur astronomers would even use them when the Moon is out or if they live in heavily light polluted areas as these filters would practically eliminate the effects of light pollution as a side effect. By applying longer exposure time you will increase the brightness of the nebulosity whilst stars will still appear much fainter than if they were imaged with LRGB filters. The sky's background will also stay darker hence contrast will be increased.
