he Skywatcher Black Diamond BD1201 OTA Refractor Telescope is another premium refractor OTA from Skywatcher. It boasts a 120mm aperture and a focal length of 1000m. It is perfectly suited for viewing deep space objects, enhanced surface details of the moon and planets, and other interesting objects in the night sky.
The Refractor Advantage
The classic refractor design delivers a unique star gazing experience. Since it uses a lens instead of a mirror and has less parts, it is able to transmit more light into the eyepiece. Multi-coated optical surfaces further enhance this capability by ensuring that light is transmitted properly and not reflected by the lens’s surface.
Portable and Easy to Set up
OTA tubes are meant to be usable with different branded mounts making them easily re-attached and quick to set up. The BD1201 OTA has these adaptability qualities as well as portability – it is easy to pack and carry around to your favorite stargazing spots.
Quality Materials & Durable Construction
Skywatcher is know to use only the best materials for their telescopes, such as high quality aluminum tubing that helps dissipate heat to limit expansion and premium optical glass that is coated to enhance light transmission to provide a better viewing experience that takes it above other telescopes of the same class.
