    Default New EP offering frm Masuyama



    Seems as if Masuyama has a new one coming soon. We all know the reputation and quality that Masuyama has always produced, and this focal length is one that really could grab my attention. I know it's probably only preliminary specifications, but the 6.5mm ER seems a little tight for a 85° EP. It's a cute little bugger though.

    Hello Frankie,

    and thank you for the info.
    This sounds very interesting, even if this EP has been designed for the slow scopes.
    The f=10mm, if I read it correctly, is a very useful focus length.

    I will try to get it asap,

    Hi JG,

    The 10mm is indeed the sweet spot for many scopes, and for the slower FL scopes a nice number for upper magnification viewing. I am very interested in how the edge performance measures up in the slower FL scopes also. I'm keeping an eye on this one for sure, but may have a hard time justifying it due to the 9mm & 11mm Naglers already claiming their spot.

    Hello Frankie,

    in the worst case scenario, you will sell your Naglers, ha, ha.

    In the 10mm up to 11mm range, I have
    Leica B40x
    Swarovski 45x S W
    Leitz Periplan GF 25x
    BCO 10
    Pentax XW 10mm,
    and the f=10mm are close to the bottom of the Leica Ultrawide asph. zoom (9mm - 18mm)
    So, the Masuyama would make all good thingies 7.

    Not sure, if I will ever sell one of these,

    Speaking of selling the Naglers: I actually did sell off my entire Nagler T6 collection some time back, but seeing the error of my ways I've since replaced a few select focal lengths.

    I have a later model Leitz Periplan GW version in 10x/25mm (30mm barrel) that offers astonishing views, but eye placement is extremely tricky. I compare eye placement to that similar with the Edmund 28mm RKE. You have to hover at just the perfect spot and don't breathe.

    One of these days I'm hoping to run across a pre-owned deal on the Leica asph zoom and have one of those myself.

    Hello Frankie,

    the Periplan GW series has another optics than the Periplan GF series, and this makes the difference.
    The Leica Asph Zoom is a very nice eyepiece, the problem is its price, of course.

    At this moment, we can see a mass of the Naglers and of other Tele Vue eyepieces on the 2nd hand markets in Germany, and their prices have dropped to the prices of the ES eyepieces.
    What became pretty rare are the spotting scope EPs from Leica-Swarovski-Zeiss,
    I have heard about people increasingly taking these EPs for the astronomy telescopes.

    I am on my way to add a Baader eudiascopic EP to my collection, so I will report later.

    Thank you for your comments,

    Mounts: Celestron SLT w/ pier mod & EQ-3 tripod, Celestron hypertuned CG-5 w/ tracking motor & Argo Navis, Manfrotto 028B w/ Stellarvue M2C, Manfrotto 055PRO w/ 128RC, TAL-1 HD EQ, Vixen SXP w/ HAL-130 SXG & half pier

    ... or you may stretch your 102mm f/6.5 with a low power Barlow, or field flattener,
