Description

Named after their venerable GoTo system, the Celestron NexStar 102SLT 102mm f/6.5 Refractor Telescope is a complete platform for making observations of the moon, planets, and bright deep-space objects such as binary stars, star clusters, galaxies and nebulae. The combination of large aperture and shorter focal length translates to a fast f/6.5 focal ratio making this iteration of the NexStar telescope series ideal for wide-field astrophotography or making detailed images of the moon. Celestron includes two eyepieces and a diagonal, plus an unmagnified finderscope and stainless steel adjustable-height tripod.

Controlling the motorized single-arm fork mount is the NexStar computer hand controller. Set up is made easy through the use of several alignment procedures, and keeping objects centered is accomplished with variable tracking rates. Packed with over 4000 celestial objects in its database and expanded information on over 100 of those objects, users have the ability to add 99 of their own objects to help customize their experience. For fast observation sessions, simply choose Tour mode the NexStar build a selection of the best objects for that date, time, and location and automatically go to those objects.

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.	Great
Planetary Observation:	Very Good
Binary and Star Cluster Observation:	Very Good
Galaxy and Nebula Observation:	Fair
Photography:	No
Terrestrial Photography: Photographing terrestrial objects (wildlife, scenery, 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 photography. Scopes with focal ratios of f/10 and faster and apertures under 5" to 6" are generally the most useful for terrestrial photography due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes.	No
Lunar Photography: Photography of the Moon is possible with virtually any telescope, using a 35mm camera, DSLR, or CCD-based webcam (planetary imager). While an equatorial mount with a motor drive is not strictly essential, as the exposure times will be very short, such a mount would be helpful to improve image sharpness, particularly with webcam-type cameras that take a series of exposures over time and stack them together. Reflectors may require a Barlow lens to let the camera reach focus.	No
Planetary Photography:	No
Star Cluster / Nebula / Galaxy Photography:	No
