    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 ...

    X derivations

    WTX115 with the Swaro 1.7x extender I concluded that the WTX isn't a replacement for the use of the 1.7x extender, since this last result on better image quality (as expected...), and resolution. However, is possible to use the WTX combo with the 1.7x extender also: - I had concluded before that...

    Field work approved!!! This solution made my day!... (y) On 30-70x mode (without the extender...), I spotted a nasal marked acuta at 235m that I almost could read the code. Added the combo and voilá! With the extender I would also read the code but wouldn't mount it so fast as with this...

    The zooming only showed more the aberrations on field work conditions...:cry: Will return to the reducer with the Baader zoom to see how resolution results...

    X derivations

    Well it reaches focus and with a pair of APM SZ the result is: I remembered that the APM SZ vignetted a bit at lower mag position with the Linear BV but using a pair of SZ isn't much a problem since isn't so noticeable because the brain "eliminates" most and with the X115 the vignetting is...

    X derivations

    I did tested and the result is: This solution almost don't vignette at lower mag - 40x - and with the resulting eye-relief (the FSA-L2 induces an increase of the ER...), makes almost the eye-piece "invisible"! Also noticed that zooming the FSA-L2 seems to not increase resolution, so the loss of...

    Don't know what telescope you use but all scopes that go over 60x need a good tripod and tripod head. The showed combo is comparable in length to an astro-combo that I use for cr-birding - see My preferred CR-telescopes - just update the X95 by the X115... ;) One of the goals of the tested...

    The WTX115 - 92ºAFOV with 4.2x total zoom!!! Using a STX115+TLS_Apo23+Nikon_FSA_L2+ES92_17mm, with some T spacers to guarantee parfocal zooming - see photo. At lower mag, with both X115 zoom and FSA_L2 zoom, at minimum zoom positions there is some vignetting, so the mentioned zoom factor is...

    The LTX115 - using the Linear BinoViewer! It took longer that I wanted but meanwhile I reached some nice solutions: with a pair of Baader Morpheus 14mm, it results on a FOV of 94% of the STX115 at 30x, but with an AFOV of 76º and 41x of magnification; with the Baader Zoom MIII, it results on a...

    Another alternative to the BTX that zooms!!! Today I tried another solution with a binoviewer that results on an increase of more than 40% of TFOV of the X115, with 76º AFOV!!! :cool: Only next Sunday I will have time to do measurements and take photos of the final version but you can have an...

    Just to clarify: the 2.34x zooming of the STX115 doesn't reduce image quality within the resulting 38-89x zoom range, and result almost parfocal with this setup - I will try to make it totally parfocal...; the FSA_L2 has a 3.5x zoom, and is this zoom that isn't worthwhile to use since degrades...

    Another alternative to the BTX and this zooms!!!... Using a STX115+TLS_Apo23+Nikon_FSA_L2+Baader_MarkV+TS_SV30 - the last 3 items with some modifications... The length of the combo almost doubled... The FOV reduced 1.36x but mags seem only to increase 1.27x the minimum magnification, i.e. the...

    There are coincidences in our life and when I posted last reply I was far of expecting that the following day I would be looking through a STC56!!!!... The test was in-side although looking to out-side through an open door. I really need a field test!!! The idea from the last post was so present...

    If you want to obtain larger FOVs than your X95/X115 allows presently, see An expensive and heavy idea - just noticed that I posted it initially on the Zeiss forum but last post makes more sense in the Swaro forum... ;)

    New straight erector for the X At the same time I uploaded my contact with the Harpia 95 vs. X95, I uploaded also a new straight erector for the X lens module that produces high image quality with astro-eyepieces (read the text and see the photo at the end of the X derivations), that is...

    X lens for photo I never made a real test comparing the X95 lens module to my TMB92, side by side, to use as telelens, due lack of time... These holidays I remembered to only take my X95 instead of also taking the TMB92, saving space and weight, so took the adapter to use the X95 lens as a...

    Solved!... Found a combo material that allows high magnification use of the X modules - have a look at http://www.pt-ducks.com/cr-telescopes.htm#Swarovski_X_derivations Will have to test it on field and do resolution tests but seem that I found a high power alternative to X95 use!... :king...

    X binoviewer Observing with 2 eyes is much better...o:D However at high magnifications de resolution still isn't also the ideal... The focus range allows >3x zoom, in the photo with constant 60º AFOV! Had some other ideas of using a binoviewer with the X95 but will take some time to get the...

    I started some tests using the X95 lens module http://www.birdforum.net/showthread.php?t=333057 Still didn't reached a combo with a definition as good as the original STX95 but the image quality is good already although not spectacular as the original... The limitation is at high powers and a...
