Baader 1.25" CaK Line Filter for Sale

update as of 11 February...found a new use for this filter

Hi everyone....

I have been doing a lot of cleaning around the observatories this fall and have decided that the Baader K-Line filter that I purchased a year ago is not being used...long story, but was part of a planned mod which I have abandoned.

If anyone is interested, this filter is mounted in a standard 1.25 cell and gives you an image that seems to be a blend of white light and CaK.

These list new in the $357US range...asking $250US...will ship internationally. If interested let me know and we can sort out shipping and transaction fees. I have the case for it too. Please e-mail or PM me...replies to the posts do not go to my mail.
