Los mejores oculares para telescopios

Esto no pasa con el colimador Hotech.

This is the biggest full-tube dobsonian telescope from GSO. To transport it, you will need a big car. But under the skies, this big telescope offers images similar to astrophotos. You will see fine structures in galaxies and nebulars and many objects begin to show colour. Also on planets, the big aperture will show many details, you only know from photos. Excellent Visual Performance: For best possible image quality you need high quality optics as well as optimized mechanics.

Since you need to move the Dobsonian manually it is particularly important that the movement be as smooth as possible. The Hotech laser collimator is well centered and aligned which are critical factors for an accurate collimation.

Los oculares del tipo Erfle, son un derivado del tipo Kellner y en su interior cuentan con cinco o seis lentes. Considerando el ejemplo anterior puedes llegar a encontrar su nombre escrito como:. El segundo dato que necesitas es la distancia focal del ocular, este dato siempre forma parte del nombre de los oculares. Estos aumentos tan elevados se consiguen con una lente de Barlow 3x y un ocular de 4 mm en el caso del telescopio del ejemplo. Lo mismo ocurre con las lentes de un ocular, para solucionar este problema se utilizan recubrimientos en ambos lados de las lentes, en las especificaciones puedes consultar este dato.

Otro inconveniente suele ser la cantidad. Los telescopios normalmente solo incluyen uno o dos oculares pocas veces tres. La distancia focal es la distancia que hay entre el foco y la lente del ocular.

By using the CR, 3V battery as our laser power source, our laser collimator has over 65 hours of continuous use battery life time. This is the biggest full-tube dobsonian telescope from GSO. This somewhat annoying effect does not occur in the Crayford focuser. Te has suscrito exitosamente a este producto. Our understanding and experiences with the laser design permit you to have an effective and precision collimation. For instance, some laser collimators actually install an off-the-shelf laser pointer in the casing. It is a very effective and essential feature to the SCA Laser Collimator in obtaining at even higher degree of accuracy with ease. At the final alignment stage, the user must bring the laser dot back to the laser exit the center of the 45 degrees faceplate. There is an one-time-only preperation you need to do for SCT laser collimation. Sus anillos son capaces de adaptar casi todos los modelos disponibles. Proprietary Crosshair Laser Collimator Available With our proprietary laser crosshair, user can zero-in the laser with ease during the final collimation on the secondary and the primary mirror.

In order to compensate the optical and mechanical alignment errors of SCT, a different collimation approach is required in compare with Newtonain telescope. Product added to wishlist. Save products on your wishlist to buy them later or share with your friends. The included CR, 3V lithium battery operates well under a typical cold night and it has a 10 years shelf life. We always make optical tests on our optical banch to guarantee the high optical level of GSO Newtonians and Dobsonians. Simpler focusers tend to be shifted a little bit out of alignment, resulting in a relative movement of the object. By default, the laser will have to be position in the optical center of the SCT. For the elevation, the telescope is equiped with the Spring Tension System. Keeping the laser dot to the finest point is the key to precision collimation. The user aligns the primary mirror by referencing the shadow of the secondary in the projected DFG pattern on a wall, and user counts the DFG dots around the shadow to center in the shadow. Parameters like the alignment mechanism, mechanical and optical structure of the laser itself, and more are taken as part of our design.
