Levenhuk SKYLINE PLUS MAK 90 Telescope is a combination of an excellent Maksutov optical tube with a fantastically small size with an EQ-1 equatorial head and an adjustable height field stand. Perfect for a balcony and for weekend trips
The telescope works well as a short balcony planetary spotter , providing a very high contrast when observing bright and compact objects (Moon, planets, bright clusters and galaxies), because it is practically not burdened with chromatic aberration and is insensitive to instability ¶Æ atmosphere. In addition, it is a good choice for people looking for a very portable telescope with great observation possibilities, one that will be a companion for many trips to the dark, rural sky, while taking up very little space in the trunk of a car.
The Maksutow-Cassegrain optical system is one of the most valued optical constructions, widely appreciated for its mobility, ease of use and multifunctionality. It is an excellent choice for both astronomical observations, as well as terrestrial and airplane observations. Excellent optics ensure an exceptionally sharp image across the entire field of view. The telescope consists of a meniscus correction plate, a main mirror and a secondary mirror on the inner side of the meniscus. These telescopes have a reduced coma and only show residual chromatic aberration, giving very sharp and clear images. The great advantage of Maksutov telescopes is their compact and compact design and low weight. Due to the significant focal length and small luminosity, they are perfect for planetary observations. A construction of this kind works well in urban conditions, where the main emphasis is on objects of the solar system, not on nebulae.
The focusing is not performed through the external sliding hoist, but through the micrometric screw that moves the main mirror of the telescope. This method of focusing the image provides a very wide range of focus adjustment, thanks to which virtually any astronomical accessories work well with this tube, and the clearances on the extractor simply do not exist.
• T2 thread in the eyepiece
The eyepiece extractor is equipped with a T2 thread (M42x0.75), thanks to which you only need a T2 ring on the bayonet of your camera (Nikon, Nikon One, Canon EOS, Sony α / A to connect an SLR or mirrorless camera) , Sony NEX / E, Olympus E / 4/3, Micro 4/3, Pentax K). In this way, we can use the telescope to take pictures of the moon and planets or use it as a 1250 mm f / 14 telephoto lens.
EQ-1 equatorial mount
The "hanged" telescope was mounted on an EQ-1 class equatorial mount with an aluminum field tripod with adjustable height. It is an assembly with sufficient stiffness to conduct visual observations, and after appropriate assembly positioning, it allows to compensate the rotation of the blue sphere by moving only along the right ascension axis. In addition, the assembly can be equipped with a single-axis drive (clock mechanism).
