2x Orion Vblock filters
1x 2inch Orion Vblock filter $60.00
1x 1.25inch Orion Vblock filter $30.00
The two inch filter is in very good condition. The 1.25inch filter has a small chip on the outer edge. Seeing that these minus violet filters are mainly used for higher powers, the chip would not interfere with the light path with shorter focal length eyepieces. Apart from the chip there are no other marks or scratches. Postage $8.00 extra.
These filters are designed to reduce acromatic aberation in refractors. SOLD
