Most of us probably have some collection of eyepieces that we keep on the side, oddballs, special to us in some way. For me these are eyepieces I just find interesting in one way or another, and I like to on occassion go into the box where I keep them to have some fun observing with them for a change of pace. Some of them are quite good and I will call them into service for a stretch, depending on the scope and the mission. Anyway, was talking to Daniel Mounsey recently about some older eyepieces from times past and that got me motivated to dip into my box of special keepers. Would be interesting to see the "Seldom Seens" of others.
Here's what is pictured. Row 1 is the back, Row 4 is the front. Eyepiece numbers are from left to right.
EP1 - Gary Russell 55mm Konig XL; a special build he did for me.
EP2 - Probably a 40 or 42mm Erfle. No markings. Good views! Found on a surplus shelf in Gary Hand's store.
EP3 - 40mm Meade 3000 Plossl
EP4 - 35mm Orion Ultrascopic
EP5 - 32mm University Optics Konig II (widest TFOV of any 1.25" eyepiece)
EP6 - Rini 30mm Plossl (Paul considers this his best offering)
EP1 - Bino pair 25mm Sterling Plossl
EP2 - Bino pair 25mm Sterling Plossl
EP3 - Edmund 1 1/8" Plossl (this is a "true" Plossl design and has the floating view like the 28 RKE)
EP4 - Edmind 28 RKE (famous for its floating in space view as the housing virtually vanishes from sight)
EP5 - Vite Aspheric 23mm (super inexpensive, some plastic lenses, but they perform quite nice and weigh nothing)
EP6 - Vite Aspheric 10mm
EP7 - Vite Aspheric 4mm
ROW 3 (planetaries)
EP1 - Couture 6mm Ball Singlet (Steve Courture built a few of these for folks. Highest contrast eyepiece period!)
EP2 - Paolini 4mm Ball Singlet (mounted a 4mm Ball lens into an old Edmund Ortho I had)
EP3 - 5mm super secret planetary (exceeds performance on my 5XO! Never left prototype stage of manufacturer)
EP4 - 6mm super secret planetary (gnat's hair close to matching 6 ZAO-II. Never left prototype stage of manufacturer)
ROW 4 (vintage)
EP1 - 100+ year old brass Huygens eyepiece (courtesy of Richard Day of Skylight Telescopes in UK)
EP2 - 100+ year old brass Huygens eyepiece (courtesy of Richard Day of Skylight Telescopes in UK)
