TELRAD Telescope Reflex Sight with Mounting Base - 1001
This particular filter allows light transmission in the doubly ionized oxygen wavelengths. This is particularly good for viewing double-star systems where a lot of emissions are in the doubly ionized oxygen range.
Oxygen III (O-III) are great for viewing diffuse and planetary nebulae. The views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae are dramatically improved.
Ships to most international destinations, APOs, and FPOs.
