The new series of Dobson telescopes are optical instruments equipped with GO-TO system made with high precision. Thanks to the powerful aperture, telescopes of this type are perfect for visual observations, both of the Moon and planets, as well as - and above all - of nebulae, clusters and galaxies. Tubes of telescopes in this series are folded so that this equipment, in spite of quite a lot of possibilities, is convenient to store and transport.
Unlike other folding constructions, Sky-Watcher telescopes do not require dismantling the tube for transport. They are transported in the form of two elements - Dobson's assembly with the GOTO system and a folded tube. Such a telescope requires only a delicate collimation after being disassembled. The telescope's operation is facilitated by the patented by the Sky-Watcher pressure regulation in the height axis.
The Dobsons with the GOTO system have been equipped with the SynScan AZ driver allowing the telescope to be directed to any direction of the sky in a simple way. The user-friendly menu allows you to easily select one of more than 42,900 objects stored in the system's memory. Thanks to the use of special encoders, it is possible to manually rotate the telescope without the need to reset the GOTO system. Telescopes of this type are a great combination of the advantages of large dobsonów with the convenience of the GOTO telescope.

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.
