The optics of Celestron SC:
Despite the long focal length of Schmidt-Cassegrain optics, the tube offers a very short length, which makes the system a very compact telescope, which is characterized by extremely light transport properties. The light strikes a molded aspheric Schmidt correcting plate and will continue to cast the spherical primary mirror. This is reflected onto a secondary mirror that reflects it back towards the main mirror. The light beam passes again the primary mirror, which has a central hole. Thus the light into the eyepiece tube located at the bottom will be thrown. Thus, the system is closed and does not suffer from air turbulence, the figure could be worse. Of course this is also an optimal dust protection is provided. The Schmidt plate Multi-layer coating, which makes for light reflex and poor images.
This lens gives you convince a very good picture, contrast and sharpness, and offer great fun for planetary observation. The Schmidt-Cassegrain system is a good all-round device for observation and photography optional with a huge range of accessories. By the end of the tube at the bottom look a simple orientation is possible. Even for occasional Earth observations (eg. in close range for bird watching), the telescope can be used optimally. The SC Celestron optics are designed on an aperture ratio of about 1:10, so also is astrophotography still very possible.
By the primary mirror focusing a very large focus range is guaranteed, which makes it possible to virtually any accessory to adapt. The positioning mechanism for focusing the primary mirror two preloaded ball bearings are used to the "mirror-shifting" (a typical problem when using simple bushings) to be minimized. The use of premium materials such as CNC machined components made of aluminum, cast steel and stainless steel ensures high stability with low weight, so you do not need a very difficult construction, as may be necessary in other optical designs.
Properties of the optics:
- long focal length with short design
- Aluminum tube with a low weight
- quality XLT Mersch compensation layer
- closed system
- preloaded ball bearings for low shifting primary mirror focusing
Delivery of optics:
- optical tube with 152mm aperture and 1500mm focal length
- 25mm Plossl eyepiece
- 1.25 "diagonal
- Mounting rail
- 6x30 finderscope, just
The mount Celestron NexStar:
Finally, "Travel Pro" is the first variable fork mount from Celestron, with integrated stand, even without a tripod used. With a handle, the tube can be separated from the Celestron Travel Pro Fork Mount. So you can take the appearance as hand luggage on the plane and give up the mount in a suitcase. Other telescopes can be connected for different tasks at the same fork mount, a solar telescope or more cameras with different lenses, etc. as
GoTo controller with "SkyAlign". As simple as it was never a telescope align: no optical levels, no filing, no compass, no polar star needed (balcony observatory) Just enter location coordinates and time that target any three stars whose names need to know do not you and "Enter" key. . Already familiar with the telescope to the sky above him and goes up to 40,000 pre-programmed objects, as directed by an invisible hand.
Updateable Hand Controller: Future-proof, thanks to Flash EPROM technology, the software can control any time via the Internet to bring the latest position.
GPS module (optional): to save you typing time and location coordinates. This GPS module receives the data directly from GPS satellites and reads them automatically each time the controller.
Remote control via PC: The included program "NexRemote" allows remote control of the telescope with any laptop / PC.
