Here is the 2017 Eyepiece Buyer's Guide.
Place your telescope's focal length at the top of column O (where the red letters are) and hit enter, and your telescope's f/ratio at the top of column P and hit enter.
All the various fields will populate with information for your scope at that point.
Some notes:
1) Levenhuk may be gone. No dealer has stock They don't have stock. If anyone knows, send me a message.
There are other companies that may disappear in 2017.
What will happen, I don't know. Stay tuned.
2) There has been an explosion of private label offerings.
The same 60°, or 100°, or "flat field" eyepieces and lots of others are now being offered by many different re-sellers.
If the market boils down to two dozen sellers all selling the same eyepieces under private labels, there will be little point to doing a 2018 Buyer's Guide.
