Imaging Filters

High transmittance for working with both long focal ratios and fast optical systems (as fast as f/3 or maybe even f/2.8)!

SHO filters set is matched with astronomical monochrome CCD, DSLR(digital camera) to shoot astronomy objects with single channel. These filters set are commonly used by astrophotographers to present their photos in Hubble Pallete.

For all astrophotography enthusiasts, filters are one of the indispensable accessories to achieve perfect deep-sky imaging.

Superior quality Chroma LRGB filteset available in either 1.25" mounted or 31mm unmounted.

Askar’s new-launched 6nm deep-sky Duo-narrowband Filter set colour Magic is a professional astrophotography tool specifically designed for deep-sky imaging.

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
