USED - 1.25" OIII Visual Filter

Finally got a clear night and this 10nm OIII filter made the Veil Nebula pop like I’ve never seen through my 8” dob. The used condition is honestly flawless—no scratches or coating issues, just crisp contrast on the ionized oxygen lines.

Pulled the trigger on this used OIII filter and couldn't be happier—the 10nm bandwidth really cuts through light pollution. The glass looks clean with no scratches, and it threaded perfectly onto my eyepiece.

The filter screws on smoothly and the 10nm bandpass really makes the Veil Nebula pop against a dark sky. For a used piece it looks nearly flawless, which is a nice surprise.
