Ostara 1.25″ H-beta filter

The Ostara 1.25″ H-beta filter is a specialist filter for CCD imaging and visual work of H-beta targets such as the horse head nebula and California nebula. Note that it is best used from dark sky locations, and ideally telescopes of 10″ or greater for visual work.

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

Recommended for capuring H-beta emitting objects using CCD photography under dark skies

Comes packaged in a foam lined case

Product code OS337600

Available to purchase from Northern Optics
