USED 1.25" OIII Filter

Bought this used OIII filter to try on my nebula targets and it really pulls out the detail in the Veil. The condition is exactly as described, no scratches or issues with the coatings.

The threads are clean and the coatings look intact for a used piece, so I'm glad I took the chance on it. Paired with my 8-inch dob, the contrast on the Ring and Dumbbell really popped last night.

Just used this on a faint planetary nebula and the contrast improvement was immediate — the central star popped right out. Even with some wear visible on the threads, the optics themselves are crisp and clean.
