Voigtländer Vienna 8×42 APO | 5.3mm silmapupill | 142m/1000m vaateväli | 20.4mm silmakaugus | 90% valgusläbilaskvus | IP67 | −10°C | 770g Voigtländer Vienna APO – linnutaatide ja loodusvaatlejate lipulaev Voigtländer Vienna 8×42 APO on Vienna seeria suurim mudel – disainitud eelkõige hämaras lindude ja looduse vaatlemiseks, kus 42mm objektiivi suurem pinnala kogub maksimaalset valgust koidikul, videvikul ja pilvistel päevadel. Vienna APO seeria apokromaatiline optika korrigeerib kromaatilist aberratsiooni kolmel lainepikkusel – tulemuseks on erakordne värvitäpsus ja teravus, mida 8×42 formaadi suurem objektiiv veelgi võimendab. Voigtländer on Austria optikafirma, mis on tegutsenud Viinis alates 1756. aastast – Vienna seeria binoklid kannavad selle ajaloo traditsiooni tänapäeva apokromaatilise optikainseneeria kujul. APO optika – kolme lainepikkuse kromaatilise aberratsiooni korrigeerimine Tavalised binoklid korrigeerivad kahte lainepikkust (ED-klaas, achromat). APO (apokromaatiline) konstruktsioon korrigeerib kolme lainepikkust – punase, rohelise ja sinise – üheaegselt samasse fookuspunkti: Korrektsiooni tase Lainepikkuste arv Tulemus pildi servades Achromat (standardne) 2 Mõningane värvifringimine (lilla/roheline ääristus) ED-klaas (kõrgem tase) 2 (optimeeritud) Vähem fringimine APO (Vienna seeria) 3 Minimaalne värvifringimine, maksimaalne teravus Linnuvaatluses on APO optika eelis selgelt nähtav: puuoksal istuv tihasepaar mustritega, kelledel on peened rohelised ja kollased jooned – APO binoklis on need toonid täpselt piiritletud, ilma lilla “halo” efektita sulestiku kontrastjoontel. 90% valgusläbilaskvus tähendab, et iga fotoon, mida objektiiv kogub, jõuab silmani minimaalsete kadudega. 5.3mm silmapupill – mida see hämaruse jaoks tähendab? Silmapupill (exit pupil) on valguskimp, mis väljub okulaarist silmale. Suurem on parem hämaras: Exit pupil Ligikaudne kasutusala 2–3mm Ergas päevavalgus 3–4mm Tavaline päevakasutus 5–6mm Koidik, videvik, pilvisus 6–7mm Öine vaatlus (silm laieneb pimedas kuni 7mm-ni) 5.3mm on klassikaline “linnuvaatluse kuldstandard” – piisav hämaras (koidikul, videvikul, tihedas metsas), ilma et binokkel muutuks ülemäära suureks ja raskeks: Vienna seeria mudel Exit pupil Parim kasutusala Vienna 8×25 APO 3.1mm Reisimine, päevavaatlus Vienna 10×32 APO 3.2mm Kompaktne universaal Vienna 8×42 APO 5.3mm Linnuvaatlus, hämar valgus, mets Voigtländeri Vienna seeria kolmest mudelist pakub 8×42 kõige rohkem valgust – 42mm objektiiv kogub 1.8× rohkem valgust kui 32mm objektiiv (pindala suhe: 42²/32² ≈ 1.72). 142m/1000m vaateväli – Vienna seeria laiaim Vienna seeria mudel Vaateväli Silmapoolne vaateväli Vienna 10×32 APO 127m/1000m 50° Vienna 8×25 APO 136m/1000m 55° Vienna 8×42 APO 142m/1000m 59° 142m/1000m on Vienna seeria laiaim vaateväli. Linnuvaatluses tähendab see: Lai vaateväli koos 8× suurendusega (vähem kätevapustuse mõju kui 10× puhul) teeb Vienna 8×42 eriti sobivaks kiiresti liikuvate subjektide vaatlemiseks – rändlinnud, rannalinnud, tiirlevad kullid. 20.4mm silmakaugus – Vienna seeria suurim prillide mugavus Silmakaugus (eye relief) on vahemaa okulaarist silmani, millel kogu vaateväli on nähtav: Vienna seeria mudel Silmakaugus Sobivus prillide kandjatele Vienna 10×32 APO 16mm Rahuldav Vienna 8×25 APO 19mm Hea Vienna 8×42 APO 20.4mm Suurepärane 20.4mm on Vienna seeria suurim silmakaugus ja üks parimaid turul olevatest 8×42 binokleidest. Prillikandjad vajavad tavaliselt vähemalt 15–16mm silmakaugust täieliku vaatevälja nägemiseks – 20.4mm annab lisaruumi isegi paksude prilliläätsede puhul. Prillita vaatlejatele: silmakarpidel on tavaliselt keeratav või voltitav silmakinnitus, mis võimaldab okulaarit lähemale ajada mugavuse jaoks. IP67 veekindlus ja lämmastikutäide IP67 tähendab: Lämmastikutäide hoiab binokli siseõhk niiskusevaba: Kurikuulus “sisemisele klaasile koogub” häda, mis vaevab odavamaid binokle talvel, ei puutu Vienna 8×42 APO-ga kasutajaid. Kellele on Voigtländer Vienna 8×42 APO mõeldud? Linnuvaatlejad 8×42 on linnuvaatlejate seas kõige populaarsem binokliklass maailmas. Vienna APO optika täpsus, 5.3mm exit pupil hämaras ja 142m/1000m laias vaateväljas on koos terviklik lahendus, mida kogenud linnuvaatlejad tunnistavad. Loodusvaatlejad ja looduse dokumenteerijad Metsloomad on aktiivsed koidikul ja videvikul – just siis, kui 5.3mm exit pupil on suurim eelis. APO optika näitab loomasulestiku, karvastiku ja värvimustrite detaile täpselt, ilma värvimoonutusteta. Prillikandjad 20.4mm silmakaugus on selles hinnakategoorias erakordne – täielik vaateväli ka tavaliste prilliläätsede puhul, mugavalt ja ilma okulaari vastu klaasi surumata. Merereisijad ja jahimehed IP67 veekindlus + lämmastikutäide + –10°C taluvus teeb Vienna 8×42 sobivaks ka rannikuvaatluseks ja talviseks jahiks.
The 32 mm low power Omni eyepiece is a 4 -element premium symmetrical Plössl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufacturers who use reflective surfaces.
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics.The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

You want to collimate your Newtonian telescope to get the best possible image out of it and need a collimation aid that is precise but inexpensive.Long metal tube with crosshairsThe collimation eyepiece is simple but absolutely effective. With practice, you will be able to collimate your Newtonian telescope in just a few minutes - especially if simply finely collimating your telescope for optimal imaging. The eyepiece consists of a long metal tube, a reticule and a 45° base. The reticule gives you the orientation required for the optical axis.Collimation of refracting telescopesIf you use the eyepiece for checking the collimation of a refracting (lens) telescope, then you will see as many reflections as there are lenses in the telescope. If all the reflections are round and centred, then your telescope is well collimated.

AstroSolar Photo Film (imaging only), telescope quality, Optical Density OD = 3.8; Digital solar imaging at highest magnifications and short exposure times. Not suitable for visual observation; This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically; like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics; AstroSolar Photo Film OD 3.8 is only intended to be used by well-experienced Astro-imagers. This material is not intended to serve; for protection during visual solar observation.
When using AstroSolar® Safety Film 5.0 – mounted in front of your optics – you can image the Sun and safely look through the viewfinder of your camera – or you can directly look into the Sun with telescopes and binoculars at any suitable magnification. The coating of AstroSolar® Safety Film 5.0 is subject to constant quality control. Its reflective property and security for solar observation through optical instruments is being tested repeatedly. AstroSolar® Safety Film 5.0 reduces the intensity of solar radiation by 99,999% to a factor of 1 : 100 000 of the initial value. Multiple coating processes on both sides of the carrier film are adding up during production to result in a perfectly uniform filtering result and help in neutralizing the effect of microscopic pores in the coating hat plague conventional glass solar filters which are commonly only coated on one side of the glass.
Omegon 1.25" Skylum filter - the easy way to discover more on Mars and Jupiter Would you like more detail and contrast when observing the Moon and planets? And that the object should still look natural? - then the Omegon Skylum filter is the 'star' in your eyepiece. It amplifies details in the red or blue parts of the spectrum - see the bands on Jupiter more vividly and make out more detail on Mars. The advantages in a nutshell stronger contrast with Jupiter and Mars - see how the red details stand out deep sky objects - improved contrast with nebulae and galaxies ideal for small telescopes - the image in the eyepiece is still bright and clear 1.25" filter with filter thread also suitable for astrophotography An 'expert' for the entire night sky You do not need to spend time considering which filter might be useful for your object. The Skylum filter is universal and is suitable for many astronomical objects. It turns the night sky background slightly darker and highlights blue and red colours. It will produce more vivid details, even in reddish nebulae. One has to say - it has a real 'sky glow' effect. The filter increases contrast, but causes little attenuation. It is useful for observing the crescent phases of the Moon. It prevents blooming when observing bright planets. And what are the advantages for you? - in future, you will be able to observe these objects in even more detail. Nullifies artificial light Similar to a nebula filter, the Skylum filter only allows certain wavelengths to pass through, and reduces scattered light. In addition, it blocks the light of many street lamps - for example the spectral lines from sodium vapour lamps. The light of the astronomical objects is therefore seen more intensely by the eye. For small and large telescopes The Skylum filter has high light transmission. This makes it ideal for visual observing with small or large telescopes. It will do a good job even with an 80mm telescope. The 'nice' filter for star clusters and galaxies Do the stars looking like glittering diamonds on black velvet? That would be nice. But from the city, the sky sometimes looks like a grey concrete wall. Bur you do not have to put up with this - put the Skylum filter into your eyepiece and to start enjoying star clusters and galaxies. Already the sky looks much darker and the objects clearly more beautiful. Make more of your observing!
