I have always enjoyed seeing the sky on a clear night through telescope. Viewing through personal optics for each eye creates a feeling of being in space. This is different from viewing through a telescope. Be aesthetic, I find it very pleasing.
Most telescopes, unfortunately, simply do not collect enough light to see the real deep-sky. But what if you can find binoculars quite large to qualify as small telescopes? Will it not be like a telescope for each eye?
If you think so, Oberverk BT -127xl -SD should be ready for apocrometric triple telescope.
first impressions
These telescopes are made without any compromise. Triple’s objectives are made with the same glass (both FCD 100 and FK -61) used in expensive refractive and are fully multidiscipped. Prism is huge, which allows full coverage from any 1 the “app. (Yes, you can change the apps in seconds. More later.) The interpillary distance, which is the distance between human eyes, There is no problem with binoculars from 57 to 80 mm. Rainbow Luna is also finished with an anodized trim in pearl white paint.
The prism is set to 45 °, which is the best agreement to see objects on both low and high altitude. I found it useful for a tripod, with an elevator column so that you can adjust the appice position for those who do not have the same height.
You can buy binoculars with different types of support structures. The classic is a wooden trippai with a height bar and the swollen bolt for binoculars. The more advanced system I used is one of the Oberwork heads that sits on a manfreet 161mk2b trippai, with a crank-powered lift that can increase the binoculars by about 9 feet (2.74 meters). It is a solid small mount that keeps the binoculars without any vibration.
Even with two 5-inch triple purposes and large-scale prisms, magnesium alloys weigh these binoculars at just 24 pounds (10.9 kg). I have no trouble in establishing them by myself.
Each BT-127xl-SD is tested and collided before shipping with certified optics for magnification of 163x. The telescope comes with a strong case with wheels at one end, which simplifies transport on your favorite dark site. It takes only a few minutes to set and move the entire system down. Oberverk also provides a limited warranty of three years.
Eyes open
Let us talk about the appas and visual experiences introduced by these 5-inch telescopes, which come with a clear area of Oberwork 14 mm (46X) 70 °. You can also buy 22 mm (30x) and 7 mm (93x) app to create a versatile set. The company sells each pair in $ 319.95. The episle is locked in place with a thin ring that sits on top of the ring focusing very deeply. You personally focus on each app.
These telescopes crave dark and transparent sky. Under these conditions, visits should be seen through Sagittarius and Scorpious. Everything looks 3D. When you look with both eyes, bright objects fool the mind thinking that they are in front of the dimber expansion. The apocromatic objectives are completely color free. I have searched, but never found, any color fringing. And simply important, the stars remained only pinprints through all my apps.
BT-127xl-SD allows you to travel through the star clouds and galaxies. In fact, you can see the galaxies in them-as well as you can at the same time with a high quality 5-inch refractor. You can see all the Andromeda Galaxy (M31) floating in the depths of the Andromeda Galaxy (M31) within the region; I found the scene introduced unique. Changing the apps will definitely change magnification, but will it provide more detail? It really depends on the object. Remember, each lens is only 5 inch aperture, so there are boundaries.
The bottom line, then the point of these binoculars is not to see the closest, most detailed view of an astronomical object, but to see a unique view using both eyes at once. Which brings an important fact: the use of both eyes eliminates eye fatigue. I have spent many years that are looking through telescopes with large aperture as 24 inches with only one eye. After a while staring at an object, my eye got tired; The more I saw, the less I saw. With both eyes, I can see as long as I want. And in this case, the more you see, the more you see.
Finally, the tripod, mount and binoculars are made in such a way that they can be taken almost anywhere on the planet. Think of your most foreign observation place. Airport? Chile? Africa? There is a good chance that BT-127xl-SD can be with you.
In short, Oberwork has created something that makes dreams: a relatively light, binoculars with a 5 -inch epocromatic purposes in an attractive body. Everything about these telescopes reflects fine workmanship. They are enough compact that you go anywhere and allow ideas that will leave you happy. I recommend Manfrito Tipi with an elevator column. Everything is set in a few minutes. For budget-conscious, the app of Oberwork, both pairs that come with binoculars and provide the company to buy, are an excellent choice. Once you set a BT-127xl-SD at a star party, you can find yourself the center of attention. Something is unmistakable about large telescopes.
