I have an Orion Ultrablock Narrowband 1.25" filter for sale. It is in mint condition and hardly has been used. Great for those of you who want to filter all forms of light pollution and want contrasty views of emission and planetary nebulae. It is being sold new for $60 + shipping, but I am selling it for $45 + shipping (to 44138).
Feel free to email me with any questions!
Take care and clear skies!
