Celestron NexStar 8 SE - GoTo Schmidt Cassegrain - 203/2032mm - tube can be removed

With the NexStar SE telescope line Celestron has created a family of modern telescopes with high class optics, sturdy mechanics and state-of-the-art electronics including computerized control. All this comes at a very attractive price.


The NexStar 8SE is complete and ready for use after only a few minutes.


-- adjustable height tripod
-- modern GoTo Electronics suite
-- high power Schmidt-Cassegrain optics
-- with RedShift 7 Celestron Edition CD Rom

This is the most portable 8" GoTo telescope from Celestron.

The NexStar 8SE was optimized for maximum ease of use and excellent portability - even airline travelling is possible with this instrument. Despite this the optical performance has not been sacrificed. The NexStar 8 SE packs an optical performance comparable with several much more expensive and/or much less portable instruments!

Every amateur astronomer will confirm this: With an 8" (200mm) telescope you will cross a boundary beyond which thousands of objects become visible. The optics do not only show countless beautiful details on the moon and the planets - as a smaller achromat of 120mm aperture or a Newtonian of 150mm aperture possibly could show too. Given good "seeing" (a term that describes the negative influence of the Earth's atmosphere on visible detail) the NexStar8SE will show small discs instead of just points of light where the moons of Jupiter are. With the proper filters cloud structures in Venus' atmosphere can be seen!

On top of that the large aperture of the Celestron Nex Star 8 collects enough light so that you can see thousands of deep sky objects in detail - galaxies will reveal their spiral structure, planetaries and gas nebulae will show lots of detail and globulars are often dissolved into single stars

The optical performance of a telescope can only be utilized if you actually find the object. The NexStar GoTo mount will guide the way and slew to the object directly.

Ideal for transport: You can remove the tube from the mount

Unlike many other fork-mounted Schmidt-Cassegrains the NexStar SE line utilizes a quick release saddle plate system for attaching the tube to the mount. This allows you to assemble or disassemble the telescope within a few seconds! You can take the delicate tube with you into the airplane while putting the mount and tripod into the regular luggage.

The mount can also be used with other telescopes.

One single telescope - even the superbly versatile Schmidt-Cassegrains - can never serve perfectly in all of the different astronomical applications. With a NexStar SE instrument it is possible to augment the Cassegrain optics by a second telescope for rich field observing or by a telescope with a shorter focal length for astro imaging. The mount will accept any telescope with a Vixen-style dovetail plate and a sufficiently short tube length.


Features of the NexStar 8SE

-- Schmidt Cassegrain with
203mm aperture and 2032mm focal length
-- internal focusing mechanism by moving the primary mirror
-- Schmidt-Cassegrain thread for attaching a broad variety of accessories (a.k.a. SC-thread, 2" thread, UNC2"-24)
-- compact Starpointer red dot finder
-- extremely compact dimensions, ideal for transportation
-- the telescope can be used in table-top mode without a tripod, or it can be put on the supplied field tripod
-- state-of-the-art GoTo mount with 40,000+ object database
-- the telescope and the mount can be split easily and stored separately. The tube can be placed on other mounts, and other tubes can be placed on the NexStar mount.




XLT Coating:
The Celestron NexStar 8 SE uses a modern multi-layer anti-reflective coating on the Schmidt-Cassegrain corrector lens, and a high reflectivity coating on the mirrors. As a result the telescope has an excellent transmission. Compared with simpler coatings approximately 10% more light reaches the eyes in the important spectral region around 500nm. This is the part of the spectrum where the human eye is particularly sensitive at night.
Focusing Mechanism: One of the most important advantages of Schmidt-Cassegrains is the internal focusing mechanism. The primary mirror is moved inside the tube, thus repositioning the focal plane. This is achieved by simply turning a large knob at the back of the telescope. The great advantage of this is that Schmidt-Cassegrains have an extremely large focusing range, allowing for the use of exotic accessories that cannot be used on most other telescopes. Even binoviewers can be focused without the need for a glass path corrector.
Wedge-Align: An Excellent Tool for Polar Alignment:
When set up on an equatorial wedge the Wedge Align function will help you with proper polar alignment. No polar alignment scope is needed anymore!
- After initial GoTo alignment through Sky Align you select "Wedge Align" in the menu.
- The telescope will automatically slew to the position where the polar star should be at the time.
- Then just use the alignment mechanism of the polar wedge until the polar star is centered in the eyepiece. An optional reticle eyepiece can be very helpful for this, but even with a regular high magnification eyepiece polar alignment can be done with good precision.

Optional Accessory: The Polar Wedge
Other than the smaller SE telescopes the NexStar 6 and 8 do not have a polar wedge integrated in the tripod. A small polar wedge would not offer sufficient stability. Therefore the polar wedge for Nexstar 6 and 8 SE is optional. You can find it under "recommended accessories".

For visual use no polar wedge is needed. But you will need it for astro imaging if exposure times are longer than about 30 seconds.

Sky Align - Your Easy Way To The Stars

GoTo capable telescopes take a lot of the responsibility off your shoulders. They will automatically slew to thousands of objects, leaving you the time to do what you're out to do for: Observing! Each GoTo telescope must be aligned before it can be used properly. This procedure used to be complicated and required knowledge of at least a couple of dozen brighter stars. With Celestron's revolutionary new Sky Align this procedure has become ultra-simple:

Step 1 ... Just enter date, time and observing location.
Step 2 ... Point the telescope at three bright stars - you don't need to know which stars they are! Even planets and the moon will work.

Once you have finished this simple procedure you are ready to start observing. The telescope will slew to any object you might fancy within a moment's notice, driven by powerful servo motors.

Advantages of the NexStar SE telescopes - an overview:

high quality optical system with XLT coating for a bright image Easy to use GoTo control - latest generation "Travel Pro" ... the telescope can be easily removed from the mount Steel tube tripod - a robust field tripod, adjustable in height

The NexStar SE 2 Mount

This is one of the most important advantages of this instrument when compared to most similar instruments. The telescope can be easily removed from the mount, allowing you to use it on a different mount as well.

Additional flexibility: You can change the instrument according to your needs:

You can directly attach other instruments to the NexStar mount. The instrument only needs to have a Vixen-style dovetail plate (available separately if you don't already have one) and a short enough tube length.

One example: With our compact Side-by-side mounting plate you can attach a camera and a little guide scope for astro imaging.

Using 2" accessories on the Schmidt-Cassegrain: 2" accessories allow for larger fields of view than possible with 1.25" accessories. This makes finding objects easier and also adds to the fun of observing extended objects.

The TS 2" Kit is a real "eye opener". The kit offers nearly twice the field of view than the original eyepiece!
