The Explore Scientific 102mm f/7 Air-Spaced Triplet ED APO Telescope made Wired Magazine''s Wish List for cool gifts and is a perfect instrument for demanding wide field observing and astrophotography.

Rugged and portable, the Explore ED Triplet is a true three-element apochromatic telescope capable of producing research-level image quality. Dr. Mike Reynolds used the ED80 telescope to make the first ever images of shadow bands on clouds during the total eclipse of the sun over Easter Island on July 11, 2010.

Explore Scientific 102mm f/7 ED Apochromatic Triplet Essential Refractor Telescope Features...

The Explore ED APO telescope comes with a white aluminum tube with black accents.
Explore Scientific Air-Spaced Apochromatic Triplets have true APO optic and are diffraction limited at .25PV or better.
Genuine ED glass from Hoya Japan is used on all ED APO Triplets at Explore, for superb quality and light throughput.
Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter; and contrast is further enhanced with the installation of matte black knife-edge baffles in the optical tube assembly.
While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending your ED Triplet off to the factory is always an option, but is not required.
Heavy-duty 2" dual-speed focusers.
The included 2" diagonal has a precision-polished mirror with enhanced 99% reflective dielectric coatings. A 1.25" compression ring adapter is part of this package.
To attach your Explore Scientific Air-Spaced Triplet telescope to a variety of mounts, we have included the "Vixen-style" dovetail. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.
All Explore Scientific products come with a STAR Extended-Life-of-the-Product Warranty. Upon registration, this product will be under warranty for as long as it is manufactured, plus five years.

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:	Yes
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.	Yes
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.	Yes
Planetary Photography:	Yes
Star Cluster / Nebula / Galaxy Photography:	Yes
