Rugged sleeping bag in Olive/Black color, designed with a rectangular watchcase shape for optimal comfort and ample freedom of movement while resting. Constructed from premium polyester, featuring a tough exterior and filled with Hollow Polyester Fiber for insulation.
Achromatic refractor featuring an objective lens diameter of 120 mm and a focal length of 1000 mm.
Ideal for discerning sky enthusiasts, the telescope incorporates a tube of substantial size. The refractor is paired with a robust EQ5 equatorial mount, offering excellent stability and precise adjustments. When upgraded with a GoTo drive, the setup becomes well-suited for astrophotography.
The traditional achromatic doublet design operates at a moderate f-ratio of f/8.3. Objective lenses are fully multi-coated to enhance contrast and image brightness. The 2" rack-and-pinion focuser includes a securing clamping ring with fixation screws for accessories. Integrated with a Sky-Watcher finderscope mount, and compatible with Sky-Watcher focuser drive systems.

Constructed from 190T polyester, the outer shell offers durable resistance to abrasions and mechanical impacts, minimizing the likelihood of additional tearing. Inside, a layer of soft micro polyester 190T provides enhanced comfort for a restful sleep.
The sleeping bag's insulation is made from a layer of Hollow Polyester Fiber with a weight of 200 g/m2, known for its lightness and excellent compressibility. Quilted construction keeps the fibers securely in place, promoting uniform heat retention throughout the bag. The insulation maintains its loft and remains breathable, supporting optimal air circulation. Even after exposure to moisture, repeated washing, or heavy use, the insulation preserves its thermal insulation properties. The filling is also hypoallergenic, making it suitable for individuals with down allergies.
Equipped with a two-way zipper on the right side, secured by a velcro flap, the sleeping bag can be fully opened along its length. This design enables conversion into a blanket or joining two sleeping bags together.
Designed for ease of transport and storage, the model folds down to 40 x 20 x 20 cm and has a weight of only 970 g, ensuring effortless portability without significantly adding to your gear load.
A durable cover comes with the sleeping bag, offering protection during transport and guarding it against dirt and potential damage.
Large telescope featuring a Newtonian system mounted on a Dobsonian mount with a 20 cm diameter. Thanks to its impressive optical performance and affordable price, the instrument is an outstanding choice for both novice stargazers and advanced astronomy aficionados.
A 20 cm diameter mirror with a moderate focal ratio enables observation of real planetary details within the Solar System, and under dark skies, uncovers hundreds of celestial targets including star clusters and galaxies.
Optical system
Engineered in the classic Newtonian system, the primary mirror of the telescope is parabolic in design, measuring 200 mm in diameter with a 1200 mm focal length. With a focal ratio of f/6, users benefit from minimal coma at the edge of the field. Low coma and moderate secondary obstruction yield crisp images, delivering not only high-quality views of deep-sky objects but also planetary images rich in detail.
Pyrex mirror
All Sky-Watcher Dobson 8" and larger telescopes are equipped as standard with a mirror made from PYREX-glass, known for its minimal thermal expansion. Such construction delivers superior image clarity when compared to models using standard glass mirrors.
Mount
The Dobson mount is a straightforward and robust design, facilitating seamless movement of the telescope along both azimuth and altitude axes. Secured on both sides by a fork mount, the upper portion rotates about the base. The structure's low center of gravity and rigid build ensure greater stability than offered by equatorial mounts.
Focuser
A 2" eyepiece focuser with a 1.25" adapter is included. The smooth-operating Crayford focuser is free from play and includes a 2" extension as well as an adapter for 1.25". These extenders should be utilized separately, not together. Compatibility is assured with autofocuser drives from Sky-Watcher.
Included accessories:
- 2" adapter
- 9 x 50 finder
- Smartphone adapter
- 12.5 mm Wide Angle 70 deg. eyepiece
- 20 mm Wide Angle 70 deg. eyepiece
