The BK 80/400 OTA telescope is a two-element achromatic refractor. It will work well as a simple piece of equipment for the novice observer, allowing observations of the Moon, planets, bright star clusters, galaxies or even bright nebulae.
The telescope does not come with a mount, but it is possible to mount the tube on a photographic tripod using a suitable connector built into the tube. Due to the large focal length of the telescope, the manufacturer recommends astronomical mounts of at least AZ4 (azimuthal) or EQ3-2 (parallactic) class.
The telescope collects about 130 times more light than the human eye at night, providing the ability to observe objects up to nearly 12.1 stellar magnitudes. The size of the lens is also related to the optical resolution, which in this telescope makes it possible to resolve stars that are more than 1.8" apart.
The kit includes:
- clamps,
- Multi Plate mounting plate,
- 6x30 finder.
