The largest of the NexStar SE family with 78% more light gathering than a 6" model, the NexStar 8 SE
will enable you to see deep into the Universe. The distinctive patented fork arm with ergonomically
designed integrated hand control cradle gives solid support to Celestron's classic 8" optics. The
NexStar 8 SE features Schmidt-Cassegrain 8" aperture optics with our premium StarBright XLT coatings
and a powerful 2,032mm focal length and f/10 focal ratio.
The NexStar 8 SE has all the same
features as Celestron's most advanced computerized GoTo telescopes, including our revolutionary
SkyAlign alignment technology, a sky tour feature, a database of over 40,000 celestial objects and easy
to use hand control.
Plug the optional CN-16 GPS Accessory into NexStar's auxiliary port and
download data from orbiting GPS satellites for truly quick and easy alignments. The universe may be
full of mysteries, but using the NexStar 8 SE isn't one of them.
In the tradition of
Celestron's famous orange optical tubes, the new NexStar SE Family combines the classic heritage of the
original orange tube telescopes with state-of-the-art features including a fully computerized operating
system, flash upgradeable hand control, our superior StarBright XLT coatings, our revolutionary
SkyAlign® telescope alignment software and much more.
Whether you are a seasoned
astronomer looking for a portable scope with advanced features, or just starting your astronomy
adventure and looking for an easy way to enjoy the night sky, a NexStar SE will help you take a closer
look.
Every NexStar SE includes a version of The Sky® software Level 1 Planetarium
software for exploring the Universe on your PC and printing out custom star charts of the sky. In
addition, you receive our NexRemote software that allows you to operate your telescope via your PC.
Software package valued at over $100 included free with your NexStar SE! Celestron has brought its renowned StarBright technology to an even higher level of light transmission
with the introduction of our new optional StarBright XLT High Performance Optical Coating System.
StarBright XLT Optical System Design - You'll See The Light.
One of the most important factors in the evaluation of a Schmidt-Cassegrain telescope's optical system
performance is its transmission - the percentage of incoming light that reaches the focal plane. The
design of the XLT System accomplishes two crucial objectives: Develop a coating system that is
optimized for visual use and for CCD/Photographic imaging.
The StarBright XLT System - What Makes It Different Makes It Better
There are three major components that make up our StarBright XLT high transmission optical system
design:
1. Unique enhanced multi-layer mirror coatings
Our mirror coatings are made from precise layers of Aluminum (Al), SiO2 (quartz), TiO2 (Titanium
Dioxide), and Si02. Reflectivity is fairly flat across the spectrum, optimizing it for both CCD imaging
and visual use. Click here to see a plot of the reflectivity of XLT's Mirror Coatings.
2. Multi-layer anti-reflective coatings
Made from precise layers of MgF2 (Magnesium Fluoride), and HfO2 (Hafnium Dioxide) A rare element
costing nearly $2000 per kilogram, Hafnium gives us a wider band pass than Titanium, used in competing
coatings. Click here to see a plot of XLT's corrector transmission.
3. High Transmission Water White glass
Celestron Schmidt-Cassegrain optical systems with optional StarBright XLT coatings use Water White
glass instead of Soda Lime glass for the corrector lens. Water White glass transmits about 90.5%
without anti-reflective coatings. That is 3.5% better transmission than uncoated Soda Lime glass. When
Water White glass is used in conjunction with StarBright XLT's anti-reflective coatings, the average
transmission reaches 97.4% - an 8% improvement! Click here to see a plot of water white glass versus
soda lime.*
These three components of our StarBright XLT coatings result in one of the finest coatings available.
The peak transmission for the systems is 89% at 520 nm. The overall system transmission is 83.5%
averaged over the spectrum from 400 to 750 nm. |
