Awewsome pieza de equipo !!
Hace algunos años desde que tuve mi anterior telescopio 6'' Tasco que me metió en la astronomía / meteorología. Cuando decidí volver a esta afición, que estaba buscando un alcance mayor que lo que tenía anteriormente, pero también quería que fue controlado por ordenador, así, no sólo con el SynScan, pero con mi ordenador portátil o PC con algún tipo de software de astronomía. pero recuerde, esto es un dispositivo de usuarios avanzados, por lo que si esta es su primera compra telescopio (esperemos que no lo es!) - ser paciente, leer el manual y aprender a utilizar este alcance antes de quejarse !!! Después de pasar unas semanas investigando diferentes modelos / fabricantes, que se establecieron en la SkyQuest XX12I, por 2 razones - en primer lugar, la facilidad de instalación / derribar y segundos para la portabilidad, ya que vivo en un área metropolitana de Detroit urbana, el medio ambiente de Michigan, la contaminación lumínica puede ser un problema en algunas noches y quería un ámbito que no era demasiado difícil de derribar y llevar conmigo en el norte donde espectaculares cielos oscuros esperan en la mayoría de las noches agradables - invierno o verano. En este escrito, he tenido la posibilidad de 8 meses y tenía algunas grandes oportunidades a finales del verano principios del otoño de utilizar el alcance antes de que strarted para obtener / calor demasiado mojado por la noche, y en Michigan, primavera y otoño no proporcionan muchas noches / sin nubes claras para cualquier observación. Sin embargo, he utilizado el alcance en varias noches y estaba completamente satisfecho con el rendimiento del alcance hasta el momento. Durante el invierno me ordenó unos oculares más para la temporada primavera / verano que viene y todavía no he tenido la oportunidad de llevarla a cabo, sin embargo, pero no puedo esperar !! Sin embargo, en las noches que he tenido a salir y lo usó, el alcance funcionó de maravilla! Solía alineación de 2 estrellas y de allí utilicé El Cielo X conectada a la computadora portátil. Funcionó muy bien. A veces, sin embargo, un re-alineamiento a veces se necesita, sobre todo porque creo que alineado con las estrellas equivocadas (mi culpa). Con diferentes aumentos, es posible que necesite para acelerar / frenar el seguimiento y que es bastante fácil de hacer. Con todo, hasta ahora estoy satisfecho con esta compra (aunque a veces pienso que debería haber ido con el de 16 pulgadas, pero tal vez en algún momento del futuro) y el rendimiento y estoy buscando para comenzar la fotografía astronómica y este alcance debe permitir que empiece escarceos con eso. Y con la enorme cantidad de diferentes accesorios, este alcance debería hacer yo bien por un tiempo! El único problema que tengo con este alcance es el cable de alimentación que se suministra no es muy largo (6 pies, creo) y desde que uso una fuente de alimentación externa al poder el alcance (y no de las baterías - ya que las células 8 ''D'' REQUERIDO puede ser costoso a menos que tenga una tonelada o baterías recargables, pero aún así, las baterías se puede morir bastante rápido si el alcance es slewed / utilizado durante varias horas - por no hablar de que puede ser un verdadero fastidio en el medio de la nada y sin manera de recarga / comprar nuevas baterías) se requiere un cable de alimentación mucho más tiempo para proporcionar suficiente espacio alrededor del alcance de caminar alrededor sin tener una mesa junto a las posibilidades de la fuente de alimentación y el ordenador - lo que fueron los ingenieros pensando ?? Un observatorio real no está configurado de esa manera, ¿por qué debería hacerlo? Menos

En cualquier caso, sentimos las molestias. - A high-quality, large-aperture telescope optimized in a very light and compact package for extreme portability! The UL18 is a telescope big enough to give satisfying views for a serious observer, yet still easily transportable to dark sky locations by one person. The Hubble Optics UL18 not only delivers the premium optical experience you need to seriously explore our universe, but tipping the scales at only about 72 lbs it's one third of the weight of classical Dobsonian telescope and folded into a compact package that will fit in any car. - The UL18 is a perfect balance between a telescope with huge light-gathering capability and unbeatable portability. It will be the telescope that gets taken out of the garage or from the back of a car to be used frequently. It will provide stunning views of the heavens and a lifetime of observing enjoyment. - The UL18 has a parabolic primary with a full 18-inch diameter of optical surface, a generous 18.4” overall diameter; not an 18-inch blank with a beveled and much smaller optical surface, which is about 5% more optical surface and light gathering than any other 18” scopes in the market. In addition, with its fast focal ratio mirror, the Hubble UL18 telescope has an eyepiece location that can almost always be reached when you are standing with both feet on the ground (only 68'' from the ground when the UL18 is pointed at zenith). The Hubble UL18 is a telescope that can provide a lifetime of satisfying observing experiences in a 72-pound package! There are two versions of the UL18: f/4 and f/4.5Advantages of f/4.5:Sharper images. No need for a coma corrector at all. - Smaller central obstruction - Easier to achieve perfect collimation - Advantages of f/4:No ladder is needed for most people; while you may need one-step ladder for an f/4.5 when close to zenith direction. - Wider field of view - Both f/4 and f/4.5 will provide you the excellent views. The f/4.5 provides the perfect view for the most demanding observer, without coma corrector. A coma corrector is strongly recommended for the UL18 f/4. Please note that some counter weight will be required for f/4.5 at the bottom, which is NOT provided. - Some Features:Exclusive Sandwich Mirror Technology: Hubble optics sandwich mirror technology has been used to manufacture research-grade optical elements and proven by over a half dozen years of successful applications at research facilities such as NASA, California State Polytechnic University San Luis Obispo, for the US Army, and in amateur telescopes around the world. Hubble sandwich mirror’s open core and close back design not only allows air to circulate through the mirror, but also provide the maximum structure strength to allow a simpler mirror cell design. Why is thermal equilibrium so critical? The main issue is ''mirror seeing,'' the turbulence seen through the eyepiece of the telescope when the air above the mirror is different from the mirror itself. Since a sandwich mirror cools far more rapidly than a solid mirror of the same thickness, this major source of distortion is eliminated quickly, giving you sharp and stable views. - Semi-Enhanced Optical Coatings: The primary mirror is coated with the most recommended (by professionals) 92% Semi-Enhanced optical coatings to assure it collects as many (while scattering as little) photons as possible to focus it into a bright and contrast-rich image. The optimal 92% Semi-enhanced coating has an over-coating of precision controlled dielectric layer to maximize the reflectivity and provide excellent chemical and mechanical protection for the mirror coating. A 96% enhanced optical coating is applied on the secondary mirror. - Engineered Mirror Support: The Dobson has an extensively modeled and optimized flotation system that provides more than adequate support for the sandwich mirror. The three-point coll

En cualquier caso, sentimos las molestias. - Product image similar: Delivery without eyepiece and finder - Taurus Dobosnians are high-quality mobile telescopes with a large aperture that can be folded into a compact form during transport. Perfect for professionals and amateurs, looking for unforgettable views of deep sky objects such as nebulae, distant galaxies or globular clusters. - Secondary Mirror Heating System: The system automatically measures and compares temperature of the air and mirror. If both temperatures start to equalise, the system will react promptly in advance and slightly rise mirror’s temperature. As a result dew do not condense on the mirror. The system is very efficient depending on capacity of powerbank and atmospheric conditions it allows for couple of days of observation. System operates with a 5V source, USB port. - Some Features of the Taurus Dobsonians:Compact, light construction These Telescope encourages to travel beyond city agglomerations, in search of dark sky. - High quality optics Mirrors are made with the highest precision and carefulness by experience personnel. Hand-made shaped and constantly controlled during the whole process of production. High-quality combined with coatings protected Si - O2 guarantees impressive image quality. All parabolic mirrors have a precise marker placed on them in order to allow for more precise collimation. - Original design Combination of modern materials and classic wood makes this telescope timeless. It is not only capable of providing great images but also presents itself splendidly. All elements made in CNC technology, handmade finished and assembled with the highest precision. Wooden elements made of waterproof plywood covered with several layers of varnish. - Optimal mirror cell Even a perfect mirror will not provide good quality images if not properly fitted. Taurus uses 9, 18 or 27 point covers in their telescopes, which providing ideal weight distribution of the mirror. - Nylon lower and side supports hold mirror securely and do not cause astigmatism. In horizontal position the mirror rests on a special belt in order to distribute its mass equally. Side hold provided by 3 strong grips. The whole fitting made entirely of aluminium alloy, powder painted. Joints made of A2 stainless steel. During collimation one moves the whole fitting together with the mirror it embraces, therefore the mirror has always ideal, unchanged conditions. An additional advantage of the floating fitting is easy access to the mirror (it is not glued). It may be released at any given time for cleaning or service. The opened construction allows for faster mirror cooling. Secondary mirror fitting provided with a separator which prevents tensions. - Comfortable usage Dismantling of the telescope is very intuitional. One person may easily dismantle the telescope within a few minutes. All winders are fixed into the construction. There is no possibility of loosing one of them. Additionally provided with a systemic solution that simplifies unscrewing (particularly useful when using thick winter gloves). During transportation individual elements are fastened one another, creating a tight chunk, which facilitates relocation and secures construction and optics. Teflon pads and bearing mounting base provides smooth and precise handling even at high magnifications. The mounted base has a rotational resistance adjustment, so you can adjust the telescope to your preferences. A gust of wind or accidental hunch will not move the telescope. The top cell can be mounted in two positions by changing the position of the focuser. This allows for convenient observation from the zenith to the horizon. The telescope is designed, so that the main mirror moves as close to the ground as possible, so that the maximum height on which the eyepiece is located is minimized. - Regulated maximum load The telescope is bal

The telescope equipped with a mirror with a diameter of more than half a meter, focal length of 2135mm and very low secondary mirror obstruction, gives unlimited possibilities. Magnification of 500x is not a problem. The most unbelievable is that this giant weighs only 44kg (heaviest part 28kg) and can be folded to a small size. One person is able to pack the T500 into a small car and take it to any place in the world, far from pollution and urban lights. Optionally the telescope can be equipped with wheelbarrows with pneumatic wheels that facilitate transport in the field. - Some Features of the Taurus Dobsonians:Compact, light construction These Telescope encourages to travel beyond city agglomerations, in search of dark sky. - High quality optics Mirrors are made with the highest precision and carefulness by experience personnel.
