I much preferred the volcano top design to the newer Fujiyama design. I did have a little input on the design of the Fujiyama. At least I got rid of the undercuts😀

I've owned many volcano tops over the years, both orthos and Kellners, and never had a poor one  - although I did have a couple of exceptionally good examples - probably ones that Mr Tani gave some extra polishing!

I mainly used mine in long focus (F11 to F15) refractors, and they just seemed to be a "match made in heaven", so to speak. I used several in my 80mm F15 achromat and they made a superb double star splitting combination, and the same could be said in my D&G US 5" F15 refractor "Andromeda", now in the care of Steve (Saganite).

I agree that the BGO type flat tops had the slight performance edge, but were generally less comfortable for extended use, I felt.

I do remember 2 exceptional flat top orthos, both branded Antares HD Ortho (Hi Definition?), in 9mm and 12.5mm, which were just outstandingly sharp and contrasty. IIRC, at least one of these went to @Nightfisher a few years back.

Obviously, time moves on and more modern eyepieces can now offer a more technically advanced design/performance/value mix. I think of the Baader Morpheus range as offering the best blend of value and performance/excellence today, a kind of modern day Ortho equivalent but with wider fields and much better comfort levels..but I will always have a very soft spot for the wonderful VT orthos from Japan💘👍.
