Practically brand new - used only once - need to offload some equipment.
This is the NEW product from Adirondack - I have two of these: 1.25" Planetray Atmospheric Dispersion Corrector assemblies with 4 degree 1/10th wave coated prism coupled with a 1.25" eyepiece holder [for Visual and Imaging]. For more info as to how these work refer to the Astrovid site.
List price is $159.
Will sell for $140 for one: $270 for the pair.
Shipping extra. [will provide options upon request]
