Sky-Watcher BKMAK 127 SP telescope Optical tube

Telescope MAK 127 SP equipped with Maksutov-Cassegrain optics, which is valued for excellent sharpness and lack of chromatic aberration. It consists of a meniscus correction plate, a primary mirror, and a secondary mirror located on the inner side of the meniscus. This design is effective in urban conditions, where it is difficult to see fainter nebular objects in the bright sky. The telescope is equipped with a 1.25-inch eyepiece holder, a diagonal of the same size, and two eyepieces.

The Maksutov optical system provides high image sharpness, very good contrast, and minimal chromatic aberrations, making the telescope a valuable tool for both beginner and advanced night astronomy enthusiasts.

The heart of the telescope is the closed Maksutov-Cassegrain optical system, which uses a spherical meniscus corrector made of crown glass, a primary mirror, and a secondary mirror on the inner side of the meniscus. This solution effectively reduces coma, astigmatism, and chromatic aberration, guaranteeing an image with exceptional sharpness and clarity.

The applied multi-layer anti-reflective coatings improve light transmission and increase the contrast of the viewed image. With an aperture of 127 mm, the telescope collects about 235 times more light than the human eye, allowing observation of objects up to about 12 magnitude. Optical resolution allows for the separation of stars about 1.1 arc seconds apart.

The BKMAK 127 SP model features a compact design, making it easy to transport and store. Weighing approximately 3.4–3.5 kg, it allows for convenient use both from balconies and in the field. The construction allows the tube to be mounted on photographic tripods or astronomical mounts of the AZ4 and EQ3-2 class.

Thanks to the lens speed f/11.8, the telescope is excellent for observing the Moon, Saturn, Jupiter, or Mars. The long focal length allows for achieving high magnifications without needing very short eyepieces.
