Like new in box, used 3 or 4 times. 48mm, 2" narrowband comparable to (well, transmission lines anyway) Lumicon UHC. These Meade filters have a bad rap for their thread sizes, this one fits the meade 2" eyepieces and diagonal, TV 2" Everbrite and their 2" eyepieces (pic shows threaded into a 35 Pan). If you try it in something else the fit is at your own risk.
Asking $80 shipped priority mail USA, international we'll need to talk.
**SOLD** Thanks Sam and Astromart!
