Yes! Forgot about the Delos line.
I didn't mention the ES 68deg line as for a few reasons for me they fall into the second tear line of ok eyepieces for Newts. The ones Mirko & I mentioned I say would be the top shelf stuff - a couple of others too that I haven't mentioned too. But most of these are $$$.
There is another group that are good, save a lot of $$$, just have a few little aberrations. These are by no means fatal, and you certainly won't be trying to look through a brick. They are a compromise between $$ & performance. In many instances you may be happy just with these
. Particularly if you are $$$ conscious, these are excellent value.
GSO Superviews - based around the Erfle design. Nothing touches these for value for money. I still have my 30mm & 15mm Superviews, though I use them with outreach nights ss they are very easy for novices to use. Bintel also carries thrse under their own brand name.
Explore Scientific & Meade 68 deg. Essentially the same eyepiece - come from same factory. Nice eyepieces, though show some astigmatism in very fast Newts at the very edge of the FOV, and eye relief is tight with 20 & 16mm, as Mirko mentioned.
