For sale is a Takahashi 7mm ortho in excellent shape.
It comes with a 1.25" adapter and rear cap.
There is a small set screw mark on the barrel of eyepiece,
and an even smaller set screw mark on the adapter. Both are very
slight. The multicoated glass is clean and clear. It looks perfect.
Price is $100 shipped and insured. I will consider a trade for
Astronomik or Lumicon 2" filters, but they must be in perfect and
Thanks for looking,
