    Slight modification to the zip tie scope sight

    My version is as follows: The zip tie is tightened around an aluminium socket (made from old TV antenna pipe) of which I compressed into oval shape, the strap (taken from an old rubber boot) goes through the socket and can be tightened around the scope body. The sight sets automatically vertical...

    Observing the Moon with a spotting scope

    I don't know exactly how it was before but the scope has been fixed in the Zeiss repair, because it fell with the tripod and it's objective lens cracked and so was replaced. Maybe the scope went through more precise adjustment than out of the factory new ones, who knows? Nevertheless the star...

    Observing the Moon with a spotting scope

    My 883 sample is not perfect but pretty good still. If I remember correct I measured 1.41" resolution at 96x magnification. Maybe using 145x would make it even little better as my own vision is just 20/20, haven't tried though. In a good seeing the 145x is subjectively perfectly sharp for the...

    Observing the Moon with a spotting scope

    Couple of days ago I took my Kowa TSN 883 spotting scope to see the Moon as it was very high on the night sky. Seeing was very good so I installed APM 3.5mm XWA 1.25" astro eyepiece to have about 145x magnification and the view was very crisp, lots of detail to be seen. APM 3.5 XWA has very...

    EL 12x50 swarovision eyecups (inadequate eye relief)

    I didn't even try NL eyecups as I discovered my SLC 10x56 eyecups fit the EL 12x50 by diameter, I just had to cut them about 7mm shorter in order to get them as close to the eyelens as possible (that means they cannot be screwed upper positions anymore but I personally also don't need to do...

    EL 12x50 swarovision eyecups (inadequate eye relief)

    I got the EL 12x50 couple of days ago and solved the eye relief issue. Long story short: I used SLC 10x56 eyecups with some modifications. The original EL eyecups took away about 4 mm of the possible eye relief (from the lens surface), I managed to gain about 3 mm or slightly more and now I...

    EL 12x50 swarovision eyecups (inadequate eye relief)

    EL 12x50 swarovision eyecups (inadequate eye relief)

    I don't have the EL 12x50 yet in my hands but next week I will have opportunity to test them with my glasses. It may well be as you wrote that EL's eye relief won't be enough regardless of eyecup switching. Very few binocular have enough eye relief for my glasses and neanderthal facial...

    EL 12x50 swarovision eyecups (inadequate eye relief)

    Are any other (NL, SLC, EL range) model eyecups compatible with EL 12x50 Swarovision (pre Field Pro version to be spesific)? My problem is inadequate eye relief as the eyelenses are deeply recessed/the eyecup rim is too high so usable eye relief is lost by several mm. Maybe one solution could...
