I have a brand new unused still in box Orion Stratus 13mm eyepiece that I want to swap for a 17mm of the same, I am only interested if its in new condition and unmarked in any way, I will be strict on this. Or I will sell it for $175.
Still looking for a swap with a 17mm Stratus??
My 13mm has been used for 5 mins tops and is new. but I have others in that Magnification and will get more use from a 17mm.
