กล้องดูดาว Sky-Watcher BKP2001EQ5 8" f/5 Reflector on EQ5 Pro SynScan Goto Mount and Tripod
With a 200mm aperture, this telescope opens up new details in deep sky observing for the observer as compared to smaller telescopes. With 78% more light gathering ability compared to a 150mm telescope, even the delicate spiral arms of many galaxies and additional structures in other nebulae can be observed. Globular clusters, such as the famous M13 cluster in Hercules, can be resolved at their edges to a large degree.
The parabolic primary mirror is diffraction limited, allowing sharp images of the object. The very high-contrast optics are optimised by the use of a small secondary mirror and thin secondary mirror spider vanes, allowing sharp and bright planetary observing even at higher magnification.
The OTA has a solid 2-inch Crayford focuser for a low image shift focusing - of particular importance at high magnifications and for astrophotography. The use of 2 inch eyepieces allows the maximum possible field of view to be exploited. The telescope has an f5 aperture ratio, putting it in the class of 'fast' Newtonian telescopes, so this telescope is particularly well suited to astrophotography.
The OTA is also visually a real gem, featuring an elegant design for the both OTA and finder scope in an aesthetically pleasing shimmering black.
The advantages in a nutshell:
- relatively high light gathering power thanks to 200mm aperture
- resistant to the effects of vibration and wind
- diffraction limited parabolic primary mirror
- high-contrast image due to thin secondary mirror spider vanes and small secondary mirror
- well suited to astrophotography due to the 'fast' optics
The EQ-5 Pro GoTo mount:
This mount provides a solid platform for most medium-sized telescopes and is excellent for exploring the night sky. The polar elevation at the observing site can be set using the fine scale provided and adjusted perfectly by using two screws. A polar finder is included. Fully equipped with motors in both axes and a SynScan hand control box to give you a complete GoTo mount: the EQ-5 is suitable not only for visual observing, but also for getting started in astrophotography. With a little practice, you will soon be able to produce successful images of galaxies and nebulae.
What is in the box:
- Telescope tube
- EQ-5 Pro GoTo mount
- SynScan hand control box package
- Polarscope (installed)
- Counterweights kit
- Steel tripod with eyepiece tray
- Finderscope with bracket

About Sky-Watcher
Sky-Watcher was launched in 1999 featuring a modest line of Newtonian and refractor optical tubes, with distribution in Europe and Asia. In 2000, Sky-Watcher released their first series of Dobsonian telescopes, and two years later answered the rising popularity of digital SLRs with their first version of the famed German Equatorial Mount, the EQ6. Today, with a full product line that includes Dobsonians, APO refractors, EQ mounts, and photography products, Sky-Watcher has grown into the most popular telescope brand worldwide.
