I have one Zeiss A-25 eyepiece, and I would very much like to trade a set of my AP/Baader/Zeiss adjustable Eyepiece Holders for another similar Zeiss A-25 eyepiece so I could use them in my binocular viewer.
I originally designed, manfactured, and sold the adjustable eyepiece holders for the AP/Baader/Zeiss binocular viewer. These custm-made non-rotating adjustable eyepiece holders are meant to be replacements for the original fixed eyepiece holders and allow you to adjust each eye separately in case your eyes are different, or even if there is a small or slight difference in your eyepieces. They also allow you to use longer-barreled eyepieces like the TeleVue Radians in the AP/Baader/Zeiss binocular viewer. They were manufactured by an engineering firm that made the sample collector that will be flying to Mars on an upcomming mission so you can know that they do very fine work.
I sold all of the original ones made but kept two sets for myself. One to use and another set in case anything happened to the first set. I use my adjustable holders every time that I observe now. I would now like to trade one of my personal sets for a Zeiss A-25 eyepiece similar to the one that I have.
Thank you for considering this proposed trade.
