Celestron NexStar 8SE is a high-quality telescope in Schmidt-Cassegrain design with an active diameter of 203mm (8"), ideal for visual observations and very good for astrophotography. The quality of the planetary images obtained is not inferior to apochromats. The telescope optics are covered with patented StarBright XLT coatings. Compared to the 6" version, it collects 78% more light.
The NexStar 8SE telescope is equipped with a GoTo system with a programmed database of almost 40,000 astronomical objects.
The set includes a steel field tripod.

This device focuses a large amount of light. Looking directly at the Sun through this device can cause partial or complete loss of vision. For observing the Sun, we recommend the safest method of eyepiece projection, i.e. projecting the image of our daytime star's disk onto a sheet of paper.

>> FREQUENTLY ASKED QUESTIONS <<
(click to expand the list of questions) Question : Can a beginner assemble and operate this telescope?
Answer: We deliver a comprehensive manual in Polish to each telescope, which will tell the user how to assemble the telescope and how to use it during observations. Customers usually have no problems assembling the telescope, as long as they read the manual.
A separate issue is searching for objects in the sky during the first observations. That is why we recommend educational items from the Publications section (especially maps and astronomical guides) and Stellarium: an excellent, free "planetarium" program in Polish, ideal for learning the sky and planning observations.

Answer: Of course YES, you can connect a DSLR camera to this or any other telescope. You will need a projection adapter and a T2 ring appropriate for your DSLR camera (there are 5 DSLR camera mount standards: Canon EOS, Nikon, Olympus E, Petax K and Sony Alfa / Minolta AF). These adapters are available in our online store in the astronomy accessories section. Question : Can I attach a compact camera to this telescope? What accessories are needed?
Answer: Of course you can. You can find a suitable shelf for compact cameras in the astronomy accessories section of our online store ( universal adapter for digital compact cameras ). Question : Can a HYBRID camera (a large compact SLR-sized camera) be attached to this telescope? What accessories are needed?
Answer: You can try this, but it is not recommended. So-called hybrids are not very good for astrophotography, because they do not have the option of taking off the lens like a SLR, and they are large and have large lenses, which means that shelf systems cannot be used, and the vignetting is high, because you cannot get the lens very close to the last optical surface of the telescope eyepiece. We recommend buying a SLR or a cheap compact. 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 recommend educational publications first, which will make both using the telescope and the observations themselves more conscious and easier. In addition, it is worth considering buying planetary contrast filters and solar filter foils (available in the astronomical accessories section). Question : Can this telescope be used as a spotting scope/nature scope?
Answer: Yes, the offered Maksutov design telescope (MAK) after using an angle connector ( included in the set ) gives an uninverted, terrestrial image. Thanks to this, this telescope can be used as a good quality observation telescope. The Maksutov design is practically free of chromatic aberration, and at the same time closed, very compact (so easy to transport), known for years from valued telephoto photographic mirror lenses of various brands. Question : Can I observe both planets and nebulae with this telescope? Is this a city or country telescope?
Answer: All offered telescopes allow you to observe the planets of the Solar System (all of them) and nebulae, or more precisely galaxies, star clusters, emission nebulae, etc. A separate issue is the clarity of the details of the planets' surfaces and the number and brightness of nebulous objects. A smaller telescope has its own sky, a large one - 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 show 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 city and country telescopes, rather there are recommendations: if the telescope will be used mainly in the city, in conditions of city 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 - mirror) is recommended. Our target will be mainly planets and compact objects. In turn, under pitch-black, country skies, it is worth using a Newtonian system telescope (mirror) with the largest possible mirror we can afford, because we can count on a more stable and clearer atmosphere and great possibilities for observing nebulae. Question : Does this telescope include a tripod/mount?
Answer: Of course YES, every telescope has a mount unless it is described as OTA ( Optical Tube Assembly ). |
