    Default Oldie Meade RG Wide Angle



    I have now in my possession a 4 pc set of the old 1.25" Meade Research Grade Wide Angle EP's consisting of 7mm, 12.4mm, 15.5mm & 20mm. Digging up info on these has been much harder than I anticipated, and definitely more difficult than any info searching I have done on EP designs before.

    A small thread and conversation with some members over at CN reveals that these were seemingly marketed as an Erfle design, but upon disassembly by a few brave souls they were discovered to actually be a 1-2-1 modified Konig design. Not sure yet why Meade chose this approach, but they obviously felt it a better marketing strategy. The AFOV is supposedly somewhere in the 60ish to 70 degree range, however I have not yet determined the precise figure yet. I'm going take some caliper measurements of the field stops and see what I can calculate and come up with, but simply by a visual inspection that seems fairly accurate. The coating appear pristine and reveal that "purple-ish" hue that I'm familiar with from the quality EPs of old. They sport an aluminum bottom barrel, with no undercut, YAY!, and the 1.25 threading seems to function perfectly. (although I rarely screw a filter to the EP itself).

    I'm at home nursing my frequently acting up lower back (L5/S1) today, but hopefully by the weekend my body, weather and time will allow for some quality evaluation. If they pan out to be of the quality I'm hoping they will be, I can envision this little set as being a light weight little 'fanny pack' grab and go Lunar set to pair up with the Mak and the Twilight1.

    Thanks for looking, and clear skies my friends.

    But wait!! What is this? Could that be the mysterious Japan MOP emblem whose meaning seems so illusive?

    Hello Frankie,

    that's a very very interesting set of the eyepieces! I can read 'JAPAN MOP' on the barrel even without glasses,
    so it's a very good sign.

    Otherwise, if you are looking for a 40mm focus 70° AFOV in military grade, then here is the Rodenstock "Gigant"
    https://www.bw-optik.de/astro/anschl...-erfle-2?c=122

    I can't give it a go, as f=40mm is too long for my short achro,

    They look great. A lot of eyepieces described as 'Erfles' often turn out to be something else. I'm looking forward to your report on using them.

    Wow, that definitely looks military for sure. It actually looks like it could blow up at any moment. And a slight bit pricey I may add.

    I really want to make the comparison between the Meade 15.5 and the 20mm against the TeleVue (NJ) Widefields of 15 & 19mm. The Mak is f/12 so they both should play nicely.

    It's not as much as I thought it may be. Just guessing I would say around 13mm or so on the 20, maybe 8-10 on the 12.4 & 15,5.....and to see the full field stop in the 7mm I believe it's like negative 2mm or so. Very very tight.
