I have two new 1.25" Lumicon O-III filters purchased at RTMC this year. They're not in "like new" condition....THEY ARE NEW! I got these to replace a pair I purchased, and lost, a few years back. I then found the original pair. Those little boxes are easy to loose!
Price $60.00 each, including postage.
That’s what I paid for them and I’ll cover the postage.
