    APM Super Zoom vs. Baader Zoom

    It wasn't since didn't reached focus in some situations... Don't know if this barlow will allow reaching focus in all situations with the Mark IV version (mine is the III) - the IV needs less infocus.

    Can the geovids rangefinder binoculars be used for solely visual use?

    I used the old 15x56 version during several years and like it a lot test of 15x56 binos. However, don't remember if the old version prisms are the same of the present ones...

    Eyepiece 1.25" Wide angle?

    Hi Joachim, There are 100º AFOV eps on 1.25" format but I also adapted some 2" eps that can be transformed on 1.25" - see the ES92 on the link of the last post. The ES100_9 has more reduced eye-relief than the Ethos and some other clones, so probably is more difficult to see all field. I can...

    Eyepiece 1.25" Wide angle?

    Can you elaborate it? The 110º Ethos and clones are more difficult to see all AFOV since the eye-relief is the same - shorter in some clones. I love my Ethos 17 with my astro-combo test of >80º "zooms" since the Nikon FSA-L2 induce an increase of eye-relief and I can see almost all FOV with...

    Eyepiece 1.25" Wide angle?

    It depends on the observer and the eyepiece... Since I use eye-glasses, nowadays I prefer the ES92 eps, but give me a >100º eps with good eye-relief and I will prefer it...;)

    Eyepiece 1.25" Wide angle?

    Don't test a 100º AFOV ep if you don't want to buy one... ;) I tested an Ethos and had to get an Ethos 17... Than, other 92º, 102º and 110º "came" to me...:whistle:

    Eyepiece 1.25" Wide angle?

    Yes, but Ethos are on other league!!! Besides having much wider AFOVs, Ethos are also much more comfortable to use. The 5mm 1.25" Ethos clones need less infocus than TV so reach focus on more spotting scopes... (y) If money is no problem and 1.25" Ethos reach focus, I would go for the Ethos -...

    Harpia 95 vs. X95 - my biased contact

    Following Birdfair, will it be used to Zeiss release an 1.25" astro adapter for Harpias?...:whistle:

    Review of the KITE OPTICS APC 18x50 ED stabilized binoculars

    Still no comparison with the Canon 18x50?

    Eyepiece 1.25" Wide angle?

    Vignetting depends on the FOV and not the AFOV: - spotting scopes that accept and reach focus astro 1.25" eps can use 110º eps! The FOV limitation depend of brands and, eventually, models. From what I read, there are some Chinese made spotting scopes that have reduced aperture prisms that will...

    Future Swarovski spotting scope

    Why no interest? What you would like that the BTX hasn't?

    Future Swarovski spotting scope

    We know you are "very happy" with your scopes and that you don't have them at the same place, so can't compare them side by side. Did you ever looked through a Zeiss Harpia? At #47, I forgot to mention a wider zoom range to the future X eyepiece modules - the Harpias have wider AFOVs until the...

    Future Swarovski spotting scope

    What Peter said (y), a zooming BTX and/or a variable magnification extender - I personally would like a straight view zooming BTX... ;) It probably will get a bit heavier but doesn't need to be bigger - see NL 10x42 vs. EL 10x42 Another advantage of the modular X system is that the ocular...

    Future Swarovski spotting scope

    As expected, the 2 news from Swarovski today were the NL52s. Any-one has some information that might indicate the release of new STX/BTX/ATX versions until the end of the year? I have some decisions to make... :unsure:

    NL >=50 mm versions?

    My original post resulted from 2 facts: 1 - after using many years 15x56, I had a opportunity to either get a NL 12x42 or go for other optical material and get finally an IS binocular... As to my cr-birding use, the 12x42 wouldn't increase resighting efficiency, I decided to go for a Canon 18x50...

    Kowa 99 Update?

    Hi Henry, In the case of the X115, I'm still not sure if this version was tuned to the BTX or already to future eyepiece module versions... :unsure:

    Make bins out of scopes

    The version with the STCs looks very cool. I wonder if someone uses it hand-held?... Swaro could do a binocular with a pair of STCs, with at least central focusing...

    APM Super Zoom vs. Baader Zoom

    Some updates can be seen at CN update - still didn't found another barlow cell that allows focusing the APM superzoom with the Optolyth 100... Those that use astro telescopes for birding can find several barlow cells and resulting mags. Notice that the TMB1.8x is supposed to be very high quality...

    Does BTX work at all in bird watching?

    And that it doesn't zooms... In my case, I don't have a BTX because it's angled - I prefer straight view for my cr-birding. If there was a straight version, I probably already had a way of zooming it...;) Meanwhile, I use a custom developed solution, with a bino-viewer and an astro-telescope CR...

    X derivations

    A new version with a pair of Masuyamas 2" 32mm 85º - the FOV increased but still is 15% less than the X115 at 30x. I prefer the TMB bino combo shown at CR BinoBirding ...

    CR BinoBirding

    Just noticed that didn't posted information that a version of the #7 combo, with the eyepieces without de 2" barrels (as shown on last post...), results on a minimum magnification with wider FOV than the X95/115 at 30x. Meanwhile I replaced the TS eyepieces by a pair of Masuyamas 2" 32mm 85º and...

    ES100 - maximizing FOV

    Yes, but it depends on the scope models... On this case it vignettes but shows a wider FOV than any 1.25" eps, showing larger AFOV than a 32mm Plössl - after your post I remembered to compare it to the TS SV32 1.25" (is also possible to reach focus, removing the 1.25" barrel (the lenses are...

    ES100 - maximizing FOV

    It should result on 22x and the FOV increased 84% when compared to the HR zoom at 30x (minimum magnification) - zoom on the left and TS2" 30mm on the right. It also should be useful for digiscopy.

    ES100 - maximizing FOV

    Eventually it can be applied to all ES and HR scopes. I used a first version ES100 (see Test to 100mm scopes) - it has a male thread a bit shorter than T2, when removing the eye-piece, but T2 adapters can be used and screwed on it. I used a TS-Optics 30 mm 2" Eyepiece (TS 2" 30mm), removed the...
