Sky-Watcher 305/1500 DOB 12" GOTO Telescope

The newly released Dobson telescopes from Sky-Watcher are exceptional optical instruments featuring a high-precision GO-TO system. With their impressive aperture, these telescopes are ideal for visual observations, allowing you to explore the wonders of the solar system, nebulae, star clusters, and galaxies. The unique folding design of the telescope tubes in this series ensures convenient storage and hassle-free transportation without the need to dismantle the tube.

Unlike other folding constructions, Sky-Watcher telescopes offer a convenient transport solution. They consist of two elements: the Dobson's assembly with the GOTO system and a folded tube. Assembling the telescope after transport is a breeze, requiring only a delicate collimation adjustment. The patented pressure regulation in the height axis, exclusive to Sky-Watcher, further enhances the telescope's operation.

Equipped with the SynScan AZ driver, Dobson telescopes with the GOTO system allow for easy alignment with any direction of the sky. The user-friendly menu provides effortless access to a vast database of over 42,900 objects stored in the system's memory. Additionally, the specially designed encoders enable manual rotation of the telescope without the need to reset the GOTO system. These telescopes offer the perfect blend of the advantages of large dobsons and the convenience of GOTO functionality.

To ensure a seamless stargazing experience right from the first night, we offer telescope packages that include all the necessary accessories. These packages consist of the optical tube option, eyepieces, and a sturdy mount for easy installation.
