Make sure it s the newer version with the parabolic mirror. The views in the older konusmotor with spherical mirror are pretty bad there s a HUGE amount of coma, and nothing ever looks very sharp to me.

Sellers in stores can either be silent about these shortcomings, or simply not be aware of them. In order to protect novice astronomy lovers from shops and sellers that’re soaring up the rubbish, I wrote this article. Unfortunately, the corrector does not always work well, so the image at medium and high magnification can be blurred, surrounded by highlights and halos. In principle, such a telescope can be fixed, however, it is hardly possible for a beginner amateur in astronomy. If the focal length is declared 1000 mm, then the tube should be about 1000 mm long. If the telescope’s tube is short, but the focal length seems to be small — be careful anyway — you can put a spherical mirror in such telescopes. Such telescopes can be acquired without fear, although there is some variation in the quality of optics. Coma is a type of aberration in which the stars at the edges of the field of view look like birds (V). Coma corrector are usually used with Newton’s high-aperture parabolic telescopes (Sky-Watcher BKP150750EQ3-2, Sky-Watcher BKP2001EQ5) either in visual or in photographic mode. An example of coma corrector is Baader MPCC II, Televue Paracorr II. Lens telescopes are characterized by chromatic aberration — a colored halo surrounding bright objects (the moon, planets). The longer the focal length of the lens telescope with the same lens diameter, the weaker and smaller the chromatic halo. Fast achromates are suitable for specialized applications (observations of galaxies, nebulae, clusters with a small magnification,observation of terrestrial objects), but such telescopes are not recommended for observations of planets. Also, chromatism is not too noticeable when observed by Mars and Saturn. Also, fast achromats are quite suitable for narrowband capturing in the line of hydrogen (H-alpha) and oxygen (OIII). Mirror and mirror-lens telescopes, as well as apochromatic refractors, haven’t chromatism. The blue halo around the planet is chromatism. For camping or balcony use, they are more convenient than telescopes with long tubes, and due to the large field of view, they can be successfully used as a wide-angle instrument when observing dim objects (galaxies, nebulae, star clusters). Yes, they will show something (craters on the moon, for example), but in fact they are “toys”. It is better to add and take a telescope with a lens of 70 mm or more. I personally encountered cases when parents came to the store with their 15-year-old son behind the telescope “no more than 50 dollars” and really wanted to buy such a toy telescope for a schoolboy. Such a telescope will generally discourage the desire to get involved in astronomy (as in the “telescope can not see anything”). Image stability is very important for successful astronomical observations, since with constant shaking it is not possible to explore the object in more detail. Unfortunately, most telescopes on a complete mount shake when focusing, when touching a optical tube or from the wind. This may be quite enough for visual observations, however, some models of telescopes come in different mounts. For example, Sky-Watcher BK1149EQ1 and Sky-Watcher BK1149EQ2 with identical optical tubes differ in mounting and price. Mount EQ2, although not very stable, and payload capacity is still better than the EQ1. If there is a choice between two similar optical tubes, but with different mounts, then it is better to take a mount with better payload capacity. Another example is the Celestron PowerSeeker 80 EQ and Sky-Watcher BK809EQ2. The optical tubes are identical, and the mounts are different and Sky-Watchers’ mount more stable. I hope that my black list of telescopes will help you make a deliberate choice, and your new telescope will give you a lot of pleasant experiences. I wish you a clear sky and success in space exploration! It is necessary to purchase fixing rings. It is necessary to purchase fixing rings. Celestron Powerseeker 80 EQ is a very weak mount, although the optical tube is quite good in optics. Optics tube is good. After removing the second hood, the entire aperture is working.

The orange and black optical tube is 40 inches long, and the sturdy equatorial mount and tripod stands nearly 5 feet tall. The very complete accessory package includes a 6x30 finder scope, two plossl eyepieces, an electronic tracking motor, and even a large-format lunar map and moon filter. Refractors are known for their sharp, high-contrast views of the moon and planets, and the Konusmotor 90 includes everything I need to get sharp views of the moon right out of the box. The low-power 17mm plossl eyepiece (58x) shows a nice overall view of the moon, while the 10mm plossl (100x) can be used to zoom in for more detail. The straight wall lies between the craters Birt and Thebit, numbers 179 and 181 on the Konus moon map. Brighter deep space objects also show up nicely in the Konusmotor 90. On a moonless night, I like the way the 17mm plossl eyepiece frames the ghostly glow of the Orion nebula. Zooming in with the 10mm eyepiece, I can easily pick out all four stars of the Orion nebula's embedded multiple star, the Trapezium. The moons of Jupiter and the rings of Saturn are easy to see with the 10mm plossl eyepiece (100x). With careful focusing, I was even able to detect the Cassini division in Saturn's rings using my own Ultima 7.5mm eyepiece. Low-cost refractors like the Konusmotor 90 can be troubled by false color and spherical aberration, but I find these effects are well controlled at moderate powers. When I look at Jupiter and Saturn at magnifications over 100x however, the images are not as sharp as I see with my C102HD refractor. The standard equipment plossl eyepieces are a good match for the optical quality of the Konusmotor 90. I'd suggest adding a low-power 25mm plossl to take in the full view of deep space highlights like the Andromeda Galaxy, the Pleiades, and the Double Cluster in Perseus. The electronic motor drive included by Konus comes in handy when sharing the telescope view with others without having to constantly adjust the slow-motion knobs by hand. I find the motor to be a mixed blessing because the slow-motion knobs and the motor cannot be used at the same time. In practice, when observing by myself, I often don't use the motor. -- Jeff Phillips Pros: High-contrast views of the moon and planets Durable, low-maintenance design Everything is included, even the batteries Cons: Equatorial mount wobbles a bit while focusing Planet views could be sharper at powers over 100x The 1000mm focal length on this telescope, allows for exceptional celestial observation. The sleek Italian design of this telescope makes it the perfect observation tool for the high-powered user. This telescope has an electronic motor allowing the user to track celestial objects at the same rate of speed they move across the sky, keeping the image in the viewfinder.. The 90mm x 1000mm KONUSKY-MOTOR telescope comes with two professional style Plossl eyepieces for better viewing. A moon filter is also included with this telescope. The robust steel tripod provides maximum stability. This Refractor Telescope gathers light through the objective lens and then magnifies it through the eyepiece. Refractor telescopes are perfect for observing stars and planets and for terrestrial observation. What does it all mean? 90mm x 1000mm ? The first number refers to the size of the objective lens or the aperture of the telescope. Larger apertures provide a brighter image with greater resolution, especially in dim lighting or deep sky observation. The second number 900) refers to the focal length of the telescope or the distance the light travels from the lens to the focused image. Longer focal lengths provide more power through a variety of eyepieces. Refractor ? This type of telescope was invented by Galileo and collects light through the lens and passes it to the eyepiece where it is magnified. Refractor telescopes produce images with greater detail and contrast. Moon Filter ? A special filter that is attached to the eyepiece to reduce the brightness of the moon, allowing the observer to see more details. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness. Beide Begriffe beschreiben die horizontal gemessene Menge an Szenerie, die beim Blick durch ein Fernglas sichtbar ist.Dieser wird grob berechnet, indem man den AoV nimmt und ihn mit der Vergro?erung multipliziert. Wenn also das 10x42-Fernglas aus dem fruheren Beispiel ein AoV von 6,3 Grad hat, betragt sein scheinbarer Sichtwinkel 63 Grad. Das AAoV ist der Winkel des vergro?erten Feldes, wenn man durch ein Fernglas blickt; je gro?er also das scheinbare Sehfeld ist, desto gro?er ist das Sehfeld, das man auch bei hohen Vergro?erungen sehen kann. Im Allgemeinen wird ein AAoV von mehr als 60 Grad als Weitwinkel betrachtet. Die Ingenieure von Nikon haben ihre eigene mathematische Formel entwickelt, um das AAoV (siehe unten) genauer und praziser zu bestimmen, wodurch der Winkel im Durchschnitt kleiner wird, aber der Gro?teil der Optikindustrie verwendet weiterhin die erste Formel, um Konsistenz und Einfachheit zu gewahrleisten. Wenn es eine gro?e Zahl wie 55 oder 68 ist, bezieht sie sich auf den scheinbaren Sichtwinkel. Im Allgemeinen gilt: je hoher die Vergro?erung und je kleiner das Objektiv, desto enger ist das Sehfeld. Von dort aus konnen Sie mit der Berechnung beginnen. Wenn Sie also ein 8x42-Fernglas haben und das FoV 360' betragt, konnen Sie berechnen, dass das AoV 6,9 Grad (360 ? 52,5) und das AAoV 55,2 Grad (6,9 x 8) betragt. Wenn Sie diese Grundformeln umdrehen, konnen Sie jeden der anderen Werte extrapolieren. Um das Verhaltnis zwischen Vergro?erung und FoV zu zeigen: Wenn das Fernglas oben stattdessen ein 10x ware und das FoV gleich ware, wurde der Blickwinkel 6,9 Grad bleiben, aber der scheinbare Winkel wurde auf 69 Grad aufgepumpt werden. Es gibt jedoch eine ganze Reihe von Enthusiasten, die ihr Fernglas zur Vogelbeobachtung oder zur Beobachtung von Insekten verwenden. Viele Vogelbeobachter wunschen sich einen engen Mindestfokusabstand, der es ihnen ermoglicht, kleinste Details von Vogeln zu sehen, wie z.B. Flugelbalken, Schnabelform oder Kopfmarkierungen - wahrend die Vogel fressen. Eine Naheinstellgrenze von weniger als 3 Meter fur ein normalgro?es Fernglas ist bemerkenswert. Mit zunehmender Vergro?erung nimmt in der Regel auch der minimale Fokussierabstand zu. Anwender, die an einer kurzen Naheinstellgrenze interessiert sind, sollten gro?ere Objektive in Erwagung ziehen und die Vergro?erung auf etwa 8x beschranken. Normalerweise sind das zentrale Scharnier und der Fokussiermechanismus im Gehause untergebracht. Wahrend dies das Scharnier und den Mechanismus verstarkt, verhindert die geschlossene Brucke, dass sich Ihre Hande ganz herumwickeln. Bei einer offenen Brucke befindet sich der Fokussierungsmechanismus normalerweise in der Nahe der Okulare und ein weiterer stabilisierender Abschnitt zu den Objektiven hin, wobei der mittlere Abschnitt offen bleibt. Dies ermoglicht nicht nur einen vollstandigen Wickelgriff, sondern reduziert auch das Gesamtgewicht der Optik. Das Hauptfokussierrad ist auf der Brucke zwischen den beiden Okularen angebracht und bewegt sie symmetrisch. Bei der Zentralfokussierung verfugen viele Hersteller uber ein Dioptrieneinstellrad an einem der Okulare, um die Scharfeinstellung entsprechend den individuellen optischen Vorschriften fein einzustellen. Die Hohe der Dioptrienkorrektur wird von jedem Hersteller, in der Regel nach Modell, festgelegt und kann sich auf dem linken oder rechten Auge oder auf beiden befinden. Bei bestimmten Modellen ist die Dioptrienkorrektur in den zentralen Fokussiermechanismus integriert. Die einzelnen Fokussierungsmodelle eliminieren den Zentralfokussierungsmechanismus, um jedem Okular die Moglichkeit zu geben, unabhangig zu fokussieren. Dies ermoglicht zwar eine extrem feine und prazise Scharfeinstellung, ist aber bei gemeinsamer Nutzung oft frustrierend und sollte nur dann in Betracht gezogen werden, wenn es nur einen Hauptanwender gibt. Viele marine und astronomische Modelle sind mit diesem System ausgestattet. Fokusfreie Fernglaser haben keine Fokussiermechanismen. Sie verlassen sich auf Ihre Augen, um das Bild zu fokussieren, so dass Sie sich auf die Landschaft konzentrieren und die Aussicht genie?en konnen. Einige Benutzer mit au?ergewohnlich schlechter oder schwacher Sehkraft sollten sich wahrscheinlich von scharfefreien Modellen fernhalten, da sie das Auge stark belasten und Beschwerden wie Augenbelastung oder Kopfschmerzen verursachen konnen. Die Bewertung bestimmt, unter welchen Bedingungen die Optik eingesetzt werden soll oder kann. Sie konnen ein wetterfestes Fernglas unter feuchten Bedingungen benutzen, ohne Schaden zu verursachen. Die Luft im Inneren des optischen Tubus besteht wahrscheinlich nur aus Umgebungsluft aus der Fabrik, in der sie montiert wurden, und weist aufgrund von Klimaanlagen und anderen Faktoren normalerweise einen extrem niedrigen Feuchtigkeitsgehalt auf. Das bedeutet, dass ein Fernglas, das direkt aus der Verpackung herauskommt, unter den meisten normalen Bedingungen keine Beschlagsprobleme haben sollte, selbst wenn es mit O-Ring oder Dichtung abgedichtet ist. Abhangig von der Konstruktion und den Dichtungen sind einige wasserdichte Fernglaser auch unterschiedlich lange tauchfahig. Einige Hersteller bewerten ihre Fernglaser fur begrenzte Tiefen fur eine begrenzte Zeit; andere halten sich an die militarischen Standardspezifikationen und bewerten sie fur viel gro?ere Tiefen. Wenn Sie aus einer warmen Kabine in eine kalte Umgebung drau?en gehen, kann die Feuchtigkeit an der Innenseite der Linsen kondensieren und sie beschlagen lassen. Beschlagfreie Fernglaser sind mit Gasen wie Stickstoff oder Argon oder einer Kombination aus beiden gefullt, um ein Beschlagen zu verhindern. Das Gas ist trocken und wird unter Druck in die optischen Tuben gepumpt, wodurch die Dichtungen und O-Ringe fest an ihrem Platz bleiben.
