Skywatcher bk1206 OTA main

Note: OTA only. Mount and tripod for illustration only.


The Sky-Watcher BK1206EQ3 is an achromatic refractor with a lens diameter of 120 mm and a focal length of 600 mm. The large aperture for a refractor and a relatively short focal length gives this telescope a very wide field of view. This makes it an excellent proposition for people who want to admire large open clusters, vast nebular objects or entire fragments of the Milky Way. This OTA is also a good option for novice nightsky observers. The large field of view with this OTA helps finding objects in the sky easy.

Skywatcher bk1206 OTA 2

Note: OTA only. Mount and tripod for illustration only.

 

The set includes a Star Pointer finder and dovetail clamps for mounting the refractor on the mount. It works well for beginner observers, allowing for comfortable observations of the Moon, the Sun (using an appropriate sun filter) or planets. However, Sky-Watcher BK1206 is best for observing large star fields, entire fragments of the Milky Way. With the right eyepieces, it can provide a field of view comparable to wide-angle binoculars at a typically telescopic range. Due to this type of properties, the OTA can be used to observe comets, especially those with extensive plaits. It is very well suited for the visual observation of variable stars. With short focal length eyepieces, this OTA will also allow you to magnify objects such as the Moon and planets.

Skywatcher bk1206 OTA 3

Note: OTA only. Mount and tripod for illustration only.

 

Optical system

The Sky-Watcher BK1206 has a classic, two-element achromatic refractor tube. A system of this type guarantees good brightness of the image obtained. The OTA collects about 290 times more light than the human eye at night, providing the ability to observe objects up to nearly 12.5 magnitude (with naked eye visibility up to magnitude 6). The size of the lens is also related to the optical resolution, which in this telescope enables it to separate stars that are more than 1.2 ”apart. 

 

Skywatcher bk1206 OTA 4

Note: OTA only. Mount and tripod for illustration only.

 

Construction

The telescope tube is relatively massive, sufficient for photographing the sky with telescopes up to 150mm in diameter, but at the same time light enough that such equipment can be considered quite mobile.

About Sky-Watcher

About Sky-Watcher

Sky-Watcher was launched in 1999 featuring a modest line of Newtonian and refractor optical tubes, with distribution in Europe and Asia. In 2000, Sky-Watcher released their first series of Dobsonian telescopes, and two years later answered the rising popularity of digital SLRs with their first version of the famed German Equatorial Mount, the EQ6. Today, with a full product line that includes Dobsonians, APO refractors, EQ mounts, and photography products, Sky-Watcher has grown into the most popular telescope brand worldwide.
