I'm a little upset at how much information is missing.
I don't understand why manufacturers think that someone buying an eyepiece wouldn't want some details about the eyepiece, like apparent field of view, for example.
Some of the information came from reviews and articles about the series instead of the manufacturer's site.
So I invite the community to improve the list--if you know some of the missing information, send me a PM about it.
Or if I left out a notable brand.
One decision I made in doing the list is that I simply didn't list all the eyepieces from some Chinese companies that only sell on eBay.
There are tons of small labels selling innumerable inexpensive Chinese Plössls, for instance. I could easily have added 500-600 entries just for those.
And they come and go as stock fluctuates, so the list would be obsolete immediately.
And names change from month to month on many of them (Vite became Svbony, for example).
I was a little averse to listing KSON as a manufacturer, as I think they provide only private label stuff and only sell under that name on eBay.
But at least they have their own website.
I also did not include ALL the eyepieces on manufacturer's sites, since they are not sold directly to consumers.
It's also unclear whether some brands listed still exist (Knight Owl?) or whether the websites just happen to still be up.
And I added one series of eyepieces that won't be available till August (Explore Scientific 52°).
What's really unclear is why I keep the list up at all.
