Very good condition but not perfect. Includes original box and direction sheet. 4.33 inch OD. I used it on my 80mm Stellarvues a lot. I think it was made to fit an Orion 90mm short tube. Outside surface of lens gently cleaned twice. Always stored in original box in plastic bag. I was very pleased with the views. Sun's color through glass filter is very natural. $32 shipped CONUS. Prefer payment by postal money order. Please note my Astromart rating. Thanks for looking.
