Sky-Watcher BK 1201 EQ5 Telescope

An achromatic refractor with an objective diameter of 120 mm and a focal length of 1000 mm.

This telescope should meet the needs of even more demanding sky observers. It is characterized by a tube of relatively large dimensions. The refractor is suspended on a heavy-duty EQ5 parallactic mount, which is characterized by good stability and precision, and when equipped with a drive with GoTo system, it will prove useful for astrophotography.

This classic achromatic doublet has a moderate aperture of f/8.3. The lenses of the lens are coated with anti-glare coatings, which has a beneficial effect on image contrast and brightness. The 2" rack-and-pinion type eyepiece hood is terminated by a mounting ring with accessory clamping screws. It has a Sky-Watcher finder mount and is compatible with Sky-Watcher focuser drives.
