The Sky-Watcher MAK-90 telescope is an ideal astronomical tool for every astronomy lover - a combination of a great optical tube in the Maksutov system, azimuth mount with the GOTO SynScan tracking system with a base of 40,000 objects and a stable field tripod.
The telescope works as a short balcony planetary spotter, providing very high contrast when observing bright and compact objects (Moon, planets, bright clusters and galaxies), because it is practically free of chromatic aberration and is not sensitive to atmospheric instability. . In addition, it is a good choice for those who are looking for a very portable telescope with a lot of observation possibilities, one that will be a companion for many trips to the dark, rural sky, while occupying very little space in the trunk of the car.

The Maksutowa-Cassegrain optical system is one of the most valued optical constructions, widely appreciated for its mobility, ease of use and multi-functionality. It is an excellent choice of both astronomical observations, as well as earth observations and aircraft observations. Excellent optics provide an extremely sharp image throughout the field of view. The telescope consists of the meniscus correction board, the main mirror and the secondary mirror placed on the inner part of the meniscus. These telescopes have a reduced coma and show only a substantial chromatic aberration, giving very sharp and expressive images. A great advantage of the Maksutov telescopes is the compact and compact design and light weight. Due to their large focal length and low light, they are perfectly suitable for planetary observations. This type of construction works well in urban environments, where the main emphasis is on solar system objects, not on nebulae.

Additional advantages

• focusing
Focusing is performed not through the external sliding puller, but through the micrometer screw moving the main telescope mirror. This method of focusing the image provides a very wide range of sharpness adjustment, thanks to which virtually any astronomical accessories work well with the tube, and the clearances on the extractor simply do not exist.

• T2 thread in the eyepiece extractor
The eyepiece extractor is equipped with a T2 thread (M42x0.75), so you only need a T2 ring for the bayonet of your camera to connect the SLR (Nikon, Canon EOS, Sony ?, Olympus E, Olympus 4/3, Pentax K). In this way, we can use the telescope to take photos of the Moon and planets or use it as a 1250 mm f / 14 telephoto lens.

• solar filter with frame included
Included with the tube is a solar filter with a special foil for visual observations and taking photos of the Sun's target.

GOTO system

The patented GOTO system allows you to control the movements of the telescope with the attached remote control and to search for interesting objects from the base numbering over 42,000 items. When the telescope searches for an object, it will follow it, i.e. keep it in view, so it remains only to enjoy the wonderful images of the celestial bodies. The stepper motor system allows you to move the telescope at different speeds, starting from the speed of the planet's rotational movement (1x) and higher.

As a standard, the motor system is powered by a 12 V constant current (in the set there is a container for 8 AA batteries with 1.5V "fingers").

Warning!

This device focuses a lot of light. Looking directly at the sun through this device can result in partial or complete loss of vision. For the observation of the Sun, we recommend the safest method of spectacle projection, that is, projecting the image of the target of our day star on a piece of paper. THE TELESCOPIC KIT IS A READY REFLECTIVE SOLAR FILTER - IT'S NEVER GIVE NEGLECT ON SECURITY
