Sky-Watcher Dobson 130 telescope

The telescope is an interesting choice for those starting their adventure with astronomy. Equipped with a 130 mm primary mirror and a 650 mm focal length, it offers an f/5 aperture ratio.

In terms of optical parameters, it corresponds to the larger Sky-Watcher BK13065EQ2 model, but thanks to its compact design, it easily fits in a backpack. It features a single-arm Dobsonian mount and a collapsible tube, known from larger Dobsonian telescopes in the Sky-Watcher series, allowing it to be folded into a compact size.

Its low weight and mobility make it easy to take anywhere – to the mountains, a lake, or other locations away from city lights. In such conditions, even a relatively small mirror allows for the observation of nebulae and galaxies.

The telescope enables the observation of nebular objects, as well as numerous star clusters and galaxies. Some of the observable objects include:

Solar System Objects:

• The Moon – craters, lunar seas, mountain ranges, and structures of larger craters
• Jupiter – cloud bands and its four largest moons
• Saturn – rings, the Cassini Division, and the shadow of the rings on the planet
• Mercury and Venus – planetary phases
• Mars – polar caps
• Uranus and Neptune – visible as small disks

Deep Sky Objects:

• Hundreds of double and multiple stars
• Star clusters – open and globular, including M13 and the Double Cluster in Perseus
• Nebulae and galaxies from the Messier and NGC catalogs, such as M42 in Orion, M20 (Trifid Nebula), and M8 (Lagoon Nebula)
• Planetary nebulae – e.g., M27 and M57 with internal structure
• Galaxies from the Virgo Cluster, best seen in a dark environment
