  1. I got rid of my Explore Scientific 100 degree EPs, I like the Televues better in my Dobs. I tend to use the 10mm Ethos and Paracorr II most of the time. The cases were made by Ron Burrows at Wood Wonders in the US http://www.wood-wonders.com/

    Beautiful cases, Barry, and a wonderful collection of glass. I enjoyed looking around at Wood Wonders' website. 

    This is my final collection, my wife's words........ :rolleyes:

    Hi Trazor, you have some great eyepieces in your collection and you're obviously more dexterous than most of us with pluck foam. Neat job!

  2. Vixen says 65° on their website. That's what GotGazer 's says on the barrel, but Michael's says 72°.

    You'd think that Vixen reduced the afov without changing the name of the eyepiece. That's confusing!!

    Pincushion plays a role in how big the true fov is. The 10 mm 90° Takahashi UW (the king of pincushion distortion) has a bout the same true field as the 10 mm 82° Celestron Luminous.

  3. Yes, those are the winged rubber eye guards that came with the TV eyepieces (1990). They're not fixed. If you don't want to use them, you pull them off and the eyepieces become metal, flat-topped. The green letters on the 26 and 7.4 mm are high on the barrel and get covered by the rubber eye guards.

    The barlows and the four older TV eyepieces.are from Televue's Japan years. The Delos are engraved with "Taiwan ROC". They know how to make a good eyepiece in Asia. The Maxvisions and the Nirvana are from mainland China.

  4. Hi,

    this is my eyepiece case. It's from a hardware store. I replaced the tool board that was in the lid with finger foam. The same foam fills up the compartments to different heights, so that when the lid is closed everything is more or less fixed.

    Some eyepieces still move about a little when I carry the case, but but they are arranged so that they only touch each other with their rubber parts. Everything should be safe this way.

    In the case are:

    Giotto's rocket blower, spare eyepiece cups, some small hex keys and a 1.25" polarising filter for daytime use.

    Thousand Oaks 4" steel-on-glass solar filter, T-adapter with 1.25" nosepiece, Celestron 0.63x flattener-reducer for SCT.

    top-middle

    TV Nagler 4.8mm (82°),  TV Wide Field 15mm (65°), TV Plössl 26mm (50°), GSO Plössl 32mm (52°), TV Delos 8mm (72°).

    top-right

    Maxvision 34mm (68°), Maxvision 28mm (68°)

    bottom-right

    two TV barlows, 1.8x and 2.5x

    bottom-middle

    Maxvision 20mm (68°), Maxvision 24mm (68°), Skywatcher Nirvana 16mm (82°), TV Delos 12mm (72°) and a TV Plössl 7.4mm (50°).

    These eyepieces all work down to F/5, except the GSO. I have two more eyepieces that don't. They serve as dust stops for my telescopes: a 20mm Edscorp Erfle of 40 years old, and a 25mm Celestron that came with my SCT.

    My 70mm MiniMak spotting scope has an 8-24mm zoom, but that is not a very good eyepiece. The GSO 32mm is my preferred eyepiece on the Minimak, together with the TV 26mm and the TV 15mm (small eyepieces for a small scope).

    Well, that's it, my eyepiece case on a bright sunny day.

    Clear skies.
