Looks like Televue lenses are the most popular. Currently I don't have any filters . What should I start with? I'm thinking one of those that diminish light pollution. Any suggestions?
After some buying, selling and swapping I've finally wound up with:
APM 32mm "Superwide"
'Orion' 26mm Q70
TV 25 Plossl (first 'premium' EP I ever bought)
TV 20 T5 Nagler
TV 19 Panoptic
TV 16 Nagler
TV 13 Nagler
Pentax XW10 (still for sale!)
TMB 7mm Planetary (On its way!)
6 & 9 mm GSO plossls (nice clear, flat views)
Takahashi HiLe 5mm
(If you are part of the latest Masuyama craze-don't bother. The Takahashis are their equal and more)
Vixen LV 4mm
Celestron "Ultima" 2x barlow
I was really obsessed with EPs for a while. I've looked through literally hundreds of boutique, older, 'hand made by fairies' EPs, like Orthos, Kellners, Monocentrics, Supermonos, Abbes, Volcano tops, Flat tops etc etc. and discovered one thing:
Most out of production EPs are out of production for a reason: They're not as good as modern alternatives (IMHO). They have almost no eye relief and are difficult to use. Any effort you make finding and buying some "superior" EP from the past would have been much better spent observing.
Again (IMHO) any new Vixen, Televue, Pentax or Tak, will usually surpass the older EPs views and be much easier to use.
Don't sweat what you don't have and enjoy what you do! (Unless you actually collect them as a hobby - then just go nuts and have fun!)
I'm kind of going retro, gradually selling off my TV Panoptics and Radians, my 22mm Pan's next to go because the 32mm Brandon is so much clearer. so here's my list:
I'm probably going to replace my 22mm Panoptic with a 25mm CZJ Ortho (O-25) and my 35mm Panoptic with a 48mm Brandon. If I had a dob instead of a Mewlon on an equatorial mount, I'm sure I'd still be into the widefield eyepieces.
Baader Aspheric 31 mm.
Baader Zoom 24-8 mm.
Baader Ortho 5 mm.
Baader Vip Modular Barlow 2X
TV Ethos 21 mm.
TV Ethos 13 mm.
TV Ethos 8 mm.
TV Ethos 3,7 mm.
TV Powermate 4X
TV Powermate 5X
panoptic 24mm
neglar 20 t2
neglar 17mm t 4
neglar 9 mm t 6
ethos 17mm
ethos 6 mm
RKE 28mm
meade 32mm
televue paracorr
this is the new beastie!!!!!! ethos 17mm
The coke can has disappointing optical properties, although being free of coma, astigmatism and chromatic abberation, it was somewhat opaque. I also had to use a 4lb lump hammer to get it in the focuser.
I can best describe it's performance as "sub-optimal". Still, it's probably better than those Modified Achromat eyepieces you get with low-end SkyWatchers ...

The coke can really gives you a good idea about the size of the eyepieces.
They are really big massive eyepieces!!!!
I've never seen such gigantic eyepieces before!
