This Telescope’s Optical System . . .

  • Achromatic refractor optical system: 102mm aperture (660mm focal length f/6.47) aluminum tube. The tube is connected to the mount by a no-tool quick release dovetail for fast assembly. Fully multicoated optics for high light transmission and good contrast. A good-sized lens shade is provided to shield the lens from ambient light for improved contrast and retard the formation of dew for maximum uninterrupted observing time.

  • Finder: StarPointer non-magnifying variable brightness illuminated red dot finder on a quick-release dovetail mounting bracket. The StarPointer is a quick and easy way to point your telescope exactly to the desired object in the sky if the object isn’t one of the more than 4,000 in its database. There’s no need to worry about the inverted images you see through traditional finders. Just align the red dot seen in the StarPointer with the desired object in the sky and you’re done.

  • Focuser: 1.25" rack and pinion.

  • Star diagonal: 1.25" 90° prism.

  • Two 1.25" eyepieces: The first is a 25mm providing a magnification of 26x. The eyepiece field of view is 1.7° across, more than three times wider than the diameter of the full Moon for expansive views of open star clusters and terrestrial observing. The second is a 9mm (73x) with a 0.6° field for more close-up views of the Moon, planets, and globular star clusters.

This Telescope’s Mount . . .

  • Fork mount/drive system: Single fork arm altazimuth design with pre-installed enclosed dual DC servo motor drives. A battery pack powering the telescope for over 30 hours. An optional AC adapter and rechargeable 12V “Power Tank" battery packs are available to conserve battery life.

  • SkyProdigy computer control: The supplied StarSense-technology computer hand control has an illuminated numeric keypad and a two-line 16-character LCD display. It has a database of 4,033 stars and objects it can find and track for you, including the complete Messier and Caldwell catalogs of famous deep space objects; a selection of the brightest and best deep space objects from the Revised New General Catalog (NGC); selected SAO stars, including the best variable stars and multiple star systems; the planets; the Moon; the Sun; and more.

        When you are ready to observe, simply turn on the SkyProdigy. There’s no need to input the date, time, and your location into the SkyProdigy computer, as with other computerized scopes. Simply press a button, stand back, and watch. The scope will slew to three different parts of the sky. A CCD camera built into the mount’s fork arm will take an image of the sky at each location. The StarSense software in the scope’s computer will use those images to determine how the sky is oriented over the scope and align the SkyProdigy on the sky without your ever having to touch the scope during the process. Here’s a short video showing how the SkyProdigy works. The SkyProdigy’s CCD camera has no external output to let you view or save what it sees. Its images are only used internally to self-align the scope on the sky at the beginning of each observing session.

        Then, a few keystrokes on the SkyProdigy hand control and the computer will automatically slew your scope to any of the 4,033 objects in its memory you choose and track it so you can observe at your leisure. You can find hundreds of fascinating deep space objects your first night out, even if you have never used a telescope before. No matter what level of experience you start from, your SkyProdigy scope will unfold all the wonders of the Universe for you, your family, and your friends. 

        The SkyProdigy mount moves at nine different speeds, four for locating objects (3.5°/sec, 2°/sec, 1°/sec, and 0.5°/sec) and five for centering them (32x, 16x, 8x, 4x, and 2x sidereal). There are user-selectable sidereal, solar, and lunar tracking rates for keeping objects precisely centered while you observe them at your leisure. The StarSense computer hand control is flash-upgradeable over the internet so you can keep your SkyProdigy scope up to date for years to come.

  • Supplied software: The scope comes with a CD-ROM of TheSky X – First Light Edition planetarium and star charting software. This program is a computerized sky map that features a 10,000 object database, 75 color images, horizontal projection, custom sky chart printing, and zoom capability. It will let explore the Universe on your PC or Mac and print out custom star charts of the sky to help you find faint objects that are not in the SkyProdigy computer’s database.

  • Adjustable height tripod: The preassembled adjustable height tripod has steel legs to damp vibrations quickly. The center leg brace holds a convenient no-tool quick-release accessory tray to keep your eyepieces and accessories up and out of the dew-soaked grass.

  • Two-year warranty: All Celestron telescopes have a two-year warranty, double that of competitive scopes.
Highest Useful Magnification:
This is the highest visual power a telescope can achieve before the image becomes too dim for useful observing (generally at about 50x to 60x per inch of telescope aperture). However, this power is very often unreachable due to turbulence in our atmosphere that makes the image too blurry and unstable to see any detail.

On nights of less-than-perfect seeing, medium to low power planetary, binary star, and globular cluster observing (at 25x to 30x per inch of aperture or less) is usually more enjoyable than fruitlessly attempting to push a telescope's magnification to its theoretical limits. Very high powers are generally best reserved for planetary observations and binary star splitting.

Small aperture telescopes can usually use more power per inch of aperture on any given night than larger telescopes, as they look through a smaller column of air and see less of the turbulence in our atmosphere. While some observers use up to 100x per inch of refractor aperture on Mars and Jupiter, the actual number of minutes they spend observing at such powers is small in relation to the number of hours they spend waiting for the atmosphere to stabilize enough for them to use such very high powers.
220x
Visual Limiting Magnitude:
This is the magnitude (or brightness) of the faintest star that can be seen with a telescope. The larger the number, the fainter the star that can be seen. An approximate formula for determining the visual limiting magnitude of a telescope is 7.5 + 5 log aperture (in cm).

This is the formula that we use with all of the telescopes we carry, so that our published specs will be consistent from aperture to aperture, from manufacturer to manufacturer. Some telescope makers may use other unspecified methods to determine the limiting magnitude, so their published figures may differ from ours.

Keep in mind that this formula does not take into account light loss within the scope, seeing conditions, the observer’s age (visual performance decreases as we get older), the telescope’s age (the reflectivity of telescope mirrors decreases as they get older), etc. The limiting magnitudes specified by manufacturers for their telescopes assume very dark skies, trained observers, and excellent atmospheric transparency – and are therefore rarely obtainable under average observing conditions. The photographic limiting magnitude is always greater than the visual (typically by two magnitudes).

12.5
Focal Length:
This is the length of the effective optical path of a telescopeor eyepiece (the distance from the main mirror or lens where the lightis gathered to the point where the prime focus image is formed). Focallength is typically expressed in millimeters.

The longer the focallength, the higher the magnification and the narrower the field of viewwith any given eyepiece. The shorter the focal length, the lower themagnification and the wider the field of view with the same eyepiece.

660mm
Focal Ratio:
This is the ‘speed’ of a telescope’s optics, found by dividing the focal length by the aperture. The smaller the f/number, the lower the magnification, the wider the field, and the brighter the image with any given eyepiece or camera.

Fast f/4 to f/5 focal ratios are generally best for lower power wide field observing and deep space photography. Slow f/11 to f/15 focal ratios are usually better suited to higher power lunar, planetary, and binary star observing and high power photography. Medium f/6 to f/10 focal ratios work well with either.

An f/5 system can photograph a nebula or other faint extended deep space object in one-fourth the time of an f/10 system, but the image will be only one-half as large. Point sources, such as stars, are recorded based on the aperture, however, rather than the focal ratio – so that the larger the aperture, the fainter the star you can see or photograph, no matter what the focal ratio.

f/6.47
Resolution:
This is the ability of a telescope to separate closely-spaced binary stars into two distinct objects, measured in seconds of arc. One arc second equals 1/3600th of a degree and is about the width of a 25-cent coin at a distance of three miles! In essence, resolution is a measure of how much detail a telescope can reveal. The resolution values on our website are derived using the Dawes’ limit formula.

Dawes’ limit only applies to point sources of light (stars). Smaller separations can be resolved in extended objects, such as the planets. For example, Cassini’s Division in the rings of Saturn (0.5 arc seconds across), was discovered using a 2.5” telescope – which has a Dawes’ limit of 1.8 arc seconds!

The ability of a telescope to resolve to Dawes’ limit is usually much more affected by seeing conditions, by the difference in brightness between the binary star components, and by the observer’s visual acuity, than it is by the optical quality of the telescope.

1.14 arc seconds
Aperture:
This is the diameter of the light-gathering main mirror or objective lens of a telescope. In general, the larger the aperture, the better the resolution and the fainter the objects you can see.

Telescope Type:
The optical design of a telescope.  Telescope type is classified by three primary optical designs (refractor, reflector, or catadioptric), by sub-designs of these types, or by the task they perform.
Refractor
 
Based on Astronomy magazine’s telescope "report cards", scopes of this size and type generally perform as follows . . .
Terrestrial Observation:
Observing terrestrial objects (nature studies, birding, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial observing. Scopes with apertures under 5" to 6" are generally most useful for terrestrial observing due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes. 
Yes
Lunar Observation:
Visual observation of the Moon is possible with any telescope. Larger aperture scopes will provide more detail than smaller scopes, thereby getting a higher score in this category, but may require an eyepiece filter to cut down the greater glare from the Moon's sunlit surface so small details can be seen more easily. Lunar observing is more rewarding when the Moon is waxing or waning as the changing sun angle casts constantly varying shadows to reveal craters and surface features by the hundreds.

This is the easiest telescope to set up and view with that I've ever owned. I've had Celestron SLT's, Advanced GT's, and plain old GT's, but none of them were as easy to align. 2 minutes to unattended alignment, and the Sky is yours. I've owned Meade LXD55's and LXD75, but nothing on the market compares to the setup of this telescope. It makes beginners feel like pros, and it's accurate enough that when I go down to a 12.5mm eyepiece, the object it's tracking is still in the view area. Great Scope and Greater Mount!
