Celestron – RASA 8 Imaging Filter – H-Alpha, H-Beta, Oxygen III Narrowband Filter – Enhances Emission Nebulae

Description

🌠 Capture the cosmos like a pro — make every nebula pop!

The Celestron RASA 8 Imaging Filter is a precision narrowband filter designed exclusively for the 8” Rowe-Ackermann Schmidt Astrograph. It transmits over 85% of key emission wavelengths (H-Alpha, H-Beta, Oxygen III) while blocking over 99.5% of unwanted light pollution and skyglow, delivering high-contrast, detailed nebula images. Constructed from Schott glass with anti-reflection coatings and housed in a machined aluminum cell, it ensures premium optical performance and easy installation directly into the RASA 8’s internal filter slot.
