    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)

    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...

    More contrast with ED scopes?

    Don't know ED vs non-ED scopes but comparing Kowa Prominar 883 to Zeiss Victory Diascope 85FL reveals substantial difference in contrast: Kowa has clearly more contrasty image but very often Zeiss seems to reveal more details not only in low-light conditions but also in daylight when looking for...

    Binoculars w/ Glasses

    Swarovski SLC 10x56 HD; the most comfortable binocular I have used with glasses. Opticron Aurora 8x42 BGA WB; almost as good as the SLC 10x56. I seem to need about 19-20 mm real eye relief. (I have glasses because of astigmatism) Regards, Juhani

    Nikon Z400 MM F/2.8 T/C S Lens on Z9 anyone..?

    But your lens has a built in teleconverter and I asked how does it perform; does it degrade image quality and if, how much, and also, is af speed affected? Regards, Juhani

    Nikon Z400 MM F/2.8 T/C S Lens on Z9 anyone..?

    May I ask you The BulbMogul how does the Z 400/f2.8 built in teleconverter work; does it reduce the image quality much or is there a significant improvement if stopped down for example one f stop? Is autofocus speed affected by a noticeable amount? Regards, Juhani

    Stability in wind

    I know some who use a metal spring between the weight and the tripod. For example a spring with capasity of 10kg is used with a weight of 12 kg so the weight lies partly on the ground preventing the swinging but still offers enough weight to dampen the vibrations. Of course same can be done...

    Stability in wind

    The extra gear can be just the cords and a light canvas bag, you can use rocks, sand or what ever you find on the spot to make the weight. If you choose to sit you need to bring that seat or sit mat also so some extra gear needed anyway. Regards, Juhani

    Stability in wind

    I have a Berlebach UNI wooden tripod which weighs about 8 kg but still can't alone offer enough stability in strong winds with my Kowa 883. I don't have experience on metal tripods but I have two carbon fibre tripods also. I don't think the material itself is the most important factor but the...
