Baader ND 1.8 and ND3 filters

These 1.25" Baader ND filters (#2458345/2458346) as "as new" in original boxes etc. Bought for spectroheliograph trials and never used.

Asking $45 each delivered.

Answering a query....
The ND 1.8 is generally used with a Herschel wedge for solar imaging, and the ND3 with a wedge for visual.

Bump.
Combine the ND3 with a Continuum filter and you have a good solar observing set-up.

These will be removed from sale this weekend.....
