Con GOTO, un diámetro de 458mm y una focal de 1900mm, el nuevo Stargate 18' - 450P de SkyWatcher multiplica las hasta ahora conocidas habilidades de este tipo de equipos en captación de luz y luminosidad, llevando a todos los aficionados a la astronomía visual a un nuevo nivel de observación y experiencia en cielo profundo y planetaria, gracias a su maravillosamente rápida relación focal de f/4.1 TELESCOPIO SKYWATCHER DOBSON STARGATE 18' Con sistema de localización automática GOTO, una apertura de 458 mm y una focal de 1900 mm, el nuevo Stargate 18'-450P de SkyWatcher multiplica las hasta ahora conocidas habilidades de este tipo de equipos en captación de luz y luminosidad, llevando a todos los aficionados a la astronomía visual a un nuevo nivel de observación y experiencia en cielo profundo y planetaria, gracias a su maravillosamente rápida relación focal de f/4.1. Así mismo su nuevo y elegante diseño de sistema de barras, facilita su transporte una vez desmontado, y además permite montar el equipo y tenerlo listo para la acción en tan sólo 20 minutos. Entre otras excepcionales cualidades del Dobson SkyWatcher Stargate 18' hay que decir que la montura está provista de un suave sistema manual de movimientos en ambos ejes, altitud y acimut, ofreciendo un rendimiento excepcional tanto en observación planetaria como en cielo profundo. ¡El mejor Dobson de Telescopiomania pone las estrellas, nebulosas y planetas a tu alcance cómo nunca los has visto! El nuevo Dobson SkyWatcher Stargate 18' incluye un espejo primario parabólico de alta calidad que elimina las aberraciones esféricas inherentes propias de reflectores de focal rápida con espejo primario esférico. El espejo primario de esteDobson SkyWatcher Stargate 18', al igual que el resto de reflectores de Sky-Watcher, es parabólico para que todos los rayos de luz confluyan en el mismo punto focal de modo que la imagen observada esté perfectamente dotada de contraste y definición, obteniendo imágenes llenas de detalles. Los astrónomos de Telescopiomania han podido probar el Dobson SkyWatcher Stargate 18' y han destacado la calidad y nitidez de las imágenes que proporciona, permitiendo incluso apreciar tenues colores en M42, la Nebulosa de Orión. La mayoría de reflectores de hoy en día tienen un revestimiento del espejo con una capa de aluminio y otra de monóxido de silicio o dióxido de silicio como protección. El dióxido de silicio produce un revestimiento óptico mucho más duradero y resistente que el monóxido de silicio pero requiere una maquinaria mucho más especializada para su aplicación, que por supuesto, encarece el coste del espejo. Este tipo de protección es necesaria dado que en la mayoría de los reflectores, el espejo está en constante contacto con el aire y con el resto de elementos atmosféricos que acaban deteriorando la capa reflectante, y por tanto, se reduce la resolución del telescopio. TODOS los reflectores de Sky-Watcher están dotados de espejos primarios multi-revestidos con monóxido de silicio de serie, asegurando una óptima calidad del equipo y un excelente rendimiento a largo plazo. Características del Dobson SkyWatcher Stargate 18': Diámetro del telescopio: 458 mm Distancia focal: 1900 mm Luminosidad: f/4.1 Diseño óptico: espejo primario parabólico multirrevestido con dióxido de silicio.

En los modelos con aberturas de hasta 150 mm, el enfoque se realiza mediante un portaocular de 1,25'' con cremallera, mientras que los instrumentos con aberturas a partir de los 203 mm disponen de un enfocador Crayford. - La base de tipo Dobson cuenta con cojinetes de teflón y movimiento suave, lo que permite desplazar el telescopio con suavidad y sin esfuerzo. El tubo mantiene su posición, puesto que está suspendido en perfecto equilibrio. Los componentes son manuables y ligeros, de modo que el telescopio es fácil de transportar y se monta realizando unas pocas maniobras, sin necesidad de tener conocimientos previos ni usar herramientas. Lo que destaca a este instrumento, no obstante, es su estructura de gran estabilidad y resistencia al viento. - El localizador de objetos Orion permite localizar rápidamente más de 14 000 objetos celestes almacenados en la memoria. Lo primero que se hace con un telescopio es alinearlo según su emplazamiento momentáneo, realizando un sencilla rutina de alineación. Después, con ayuda del controlador luminoso de mano, usted elige el objetivo deseado de entre los ofrecidos en la biblioteca incluida y sigue entonces la dirección señalada por el localizador de objetos, orientando manualmente el telescopio según la flecha indicada en la pantalla. Así, en poco tiempo, el telescopio queda alineado con el objeto seleccionado, que usted verá dentro del campo visual cuando mire a través del ocular. - Los objetos se pueden seleccionar según su categoría (p. ej. planetas, nebulosas, cúmulos globulares, galaxias, etc.) o número de catálogo (p. ej. M57, NGC253, etc.). Otra posibilidad consiste en seleccionar una de las 12 visitas guiadas memorizadas, que le permitirán contemplar los objetos más interesantes y mejor visibles durante el mes en curso. Pero también es posible hacerlo a la inversa: imagínese que está dando un paseo por la bóveda celeste, y de pronto se encuentra con un objeto que usted no puede identificar pero el localizador sí. Entonces simplemente presiona el botón ID y recibirá toda la información usual sobre lo que está viendo, que incluye, entre otras cosas, el tipo de objeto, su nombre, tamaño y constelación. El localizador de objetos convierte a su telescopio en un instrumento flexible que brindará, sobre todo al principiante, alegría y diversión por mucho tiempo. - Volumen de suministro del Dobson Orion N 254/1200 Intelli - Scope:Tubo óptico con abertura de 254mm y distancia focal de 1200mm. - Enfocador Crayford de 2''.

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.
