Here’s the latest ad:
Over $1000 an eyepiece.
So what makes an 8 year or older eyepiece so special? I’ve come up with some areas that would allow them to have more contrast than all the others. (Expect maybe the Pentax XOs.)
- Glass types used - I pretty much ruled this one out. At the time the ZAOs were made, Zeiss didn’t make their own glass. So they had to have ordered and used commercially available glass, just like other manufacturers of Abbe eyepieces. So whether it’s OHARA, or Schott, or whomever, it would all be the same.
- Coatings - This could be the difference, but I have no idea how I could find out which ones they used. Any input would be appreciated.
- Polish - Now this is often touted as the reason ZAOs do better contrast wise versus other eyepieces. If someone could tell me how to measure, view, and take pictures of polish levels, I would love to hear about it. I have a 20X stereo microscope, but I’m guessing that’s not a high enough power to actually analyze the polish. What is? 500X, 1000X? I can get a higher power microscope. Is there a special procedure? Any input would be helpful.
- Mechanical design - I don’t think this is it either. Flat black, blackened lens edges. Those are all pretty standard on $125 Abbe Ortho eyepieces. So I don’t think this is a discriminator either.
So I really would like to figure this out. I am determined to find out if they really are that special, or if people are suffering from a particular psychological malady called “Purchase Price Rationalization”. It exists, and it’s where when people pay high prices for an item, they figure a way to rationalize the cost. People in the “Refractor” forums do it from time to time. Myself included.
