The new series of Dobson telescopes are optical instruments made with high precision, equipped with the GO-TO system. Thanks to their large aperture, telescopes of this type are perfect for visual observations, they are perfect for observing solar system objects, as well as nebulae, star clusters and galaxies. The tubes of the telescopes in this series are foldable, which makes this equipment, despite its considerable capabilities, easy to store and transport.
Unlike other foldable structures, Sky-Watcher telescopes do not require dismantling the tube for transport. They are transported in the form of two elements - a Dobsonian assembly with the GOTO system and a folded tube. When extended, such a telescope requires only gentle collimation. Operating the telescope is facilitated by the Sky-Watcher patented pressure adjustment along the height axis.
Dobsonians with the GOTO system are equipped with the SynScan AZ controller, which allows you to easily point the telescope to any direction in the sky. The user-friendly menu allows you to easily select one of over 42,900 objects stored in the system memory. Thanks to the use of special encoders, it is possible to rotate the telescope manually without the need to re-set the GOTO system. Telescopes of this type are an excellent combination of the advantages of large dobsonians with the convenience of using the GOTO telescope.

Author's comment on the photos:
"I am sending photos from all-night observations that we carried out on the beautiful night of September 6/7, 2013. Just yesterday I finished processing the last photo.
In the morning we looked at winter objects.
Because we were focused on observations - I only took photos during "breaks", but I'm still shocked at what this tube can do :)"
Teleskopy.pl would like to thank the author for sending further wonderful materials.

This device focuses a large amount of light. Looking directly at the Sun through this device may result in partial or complete loss of vision. To observe the Sun, we recommend the safest method of eyepiece projection, i.e. projecting the image of the disk of our day star onto a piece of paper.

>> FREQUENTLY ASKED QUESTIONS << (click to expand the list of questions) Question : Can a beginner cope with assembling and operating this telescope?
Answer: Each telescope is supplied with extensive instructions in Polish, from which the user will learn how to assemble the telescope and how to use it during observations. Customers usually have no difficulty assembling the telescope as long as they read the instructions. A separate issue is searching for objects in the sky during the first observations. That's why we recommend educational items in the Publications section (especially maps and astronomical guides) and Stellarium: an excellent, free "planetarium" program in Polish, ideal for learning about the sky and planning observations.

Answer: Of course YES, you can connect a digital SLR camera to this, as well as to any other telescope. For this purpose, you need: a projection connector and a T2 ring appropriate for your SLR camera (there are 5 standards of SLR bayonets: Canon EOS, Nikon, Olympus E, Petax K and Sony Alfa / Minolta AF). These connectors are available in our online store in the astronomical accessories section. Question : Can a compact camera be connected to this telescope? What accessories are needed for this?
Answer: Of course you can. A suitable shelf for compact cameras can be found in the astronomical accessories section of our online store ( universal adapter for compact digital cameras ). Question : Can a HYBRID camera (a large compact camera with the dimensions of a SLR) be connected to this telescope? What accessories are needed for this?
Answer: You can try this, but it is not recommended. The so-called hybrids do not work well in astrophotography because they do not have the ability to remove the lens like an SLR camera, and they are large and have large lenses, which means that shelf systems cannot be used, and the vignetting is high because you cannot bring the objective lens very close to the last optical surface of the telescope eyepiece. We recommend purchasing a SLR camera or a cheap compact camera. Question : What else is worth buying for this telescope?
Answer: The presented telescope is a complete set, ready to conduct astronomical observations on the first clear night. As an addition, we first recommend educational publications that will make both the use of the telescope and the observations themselves more conscious and easier. Additionally, it is worth considering purchasing contrast planetary filters and solar filter foils (available in the astronomical accessories section). Question : Can this telescope be used as a viewing telescope/nature telescope?
Answer: NO. This (Newton) mirror telescope is not suitable for observing terrestrial objects because it produces an up-down image ("green down") and there are no optically good ways to "restore" it. However, this does not interfere with astronomical observations, because for an Earth observer the concept of up and down makes sense on Earth, but does not exist in space. However, the Newton system telescopes work quite well in photography of ground objects and observations of aircraft at cruising altitudes. Question : Can I observe both planets and nebulas with this telescope? Is this a telescope only for the city or only for the countryside?
Answer: All offered telescopes allow you to observe the planets of the Solar System (all) and nebulae, i.e. galaxies, star clusters, emission nebulae, etc. A separate issue is the clarity of details of the planets' surfaces and the number and brightness of nebular objects. A smaller telescope has its own sky, a large one has its own, but we can always count on wonderful observations of the structures of the Moon's surface, the phases of Mercury and Venus, the disk of Mars, the belts on Jupiter and the four Galilean moons of Jupiter, the ring of Saturn and the disks of Uranus and Neptune. The brightest nebulae, such as the Great Andromeda Nebula M31, the Great Orion Nebula M42 or the globular cluster in Hercules M13 always delight, even a small telescope will reveal several dozen of the most beautiful nebulae. Finally, a telescope equipped with a solar filter can be used to observe spots on the Sun's disk. There is no division into telescopes for the city and the countryside , but rather recommendations: if the telescope will be used mainly in the city, in conditions of urban light pollution and high atmospheric instability (buildings give off heat at night, heating the air and the image starts to "float" like on hot days over a hot road!), then an achromatic refractor (lens telescope) or Maksutov (meniscus-reflector) is recommended. Our target will mainly be planets and compact objects. In turn, under the pitch-black rural sky, it is worth using a Newtonian system (mirror) telescope with the largest possible mirror we can afford, because we can count on a more stable and transparent atmosphere and great opportunities to observe nebulae. Question : Does this telescope come with a tripod/mount included?
Answer: Of course YES, every telescope has an assembly, unless it is described as OTA ( Optical Tube Assembly). Question : You write that the telescope comes with an assembly, does this mean that you will come and assemble the telescope for me?
Answer: Mounting does not mean mounting , but the system of mounting the telescope tube. You need to understand that we never make hand-held observations with an astronomical telescope - we have to mount the telescope on a system that allows it to be precisely positioned in any region of the sky. In the case of a Dobsonian mount , the optical tube of the telescope is mounted on a type of box that serves as an azimuth mount , i.e. having two perpendicular axes: a height axis ("up - down") and an azimuth axis ("left - law"). Question : I see that this telescope is quite low. How/in what position is it observed?
Answer: Telescopes with a Dobson mount have an eyepiece - the place where we look / "put our eye" - often relatively low, especially when the mirror diameter does not exceed 35 centimeters. Nevertheless, observation is possible in a standing position, and the most comfortable position is sitting - for this purpose, it is worth purchasing a height-adjustable stool or even a foldable fishing chair. The lying position is probably not practiced :-)
