The "Double Stacked" Coronado SolarMax II Solar Telescope is a beautiful instrument that sports polished brass and black finishes as well as precisely crafted tuning knobs. When you purchase a "Double Stacked" Coronado SolarMax 60 II Solar Telescope your package includes:

Coronado Hard Carrying Case
Life Time Tech Support from High Point Scientific

The "double stacked" Coronado SolarMax II is a serious instrument built for someone looking to see the finest areas of detail on our sun. Prominences, flares, filaments and ever changing surface areas of the sun will all be brought to you in high def with the SolarMax.

So why is a "Double Stacked" solar telescope better then a traditional solar telescope? The simple answer is that you get significantly enhanced optical resolution with the "double stacked" version.

Coronado has enhanced the "double stacked" SolarMax 60 by placing an additional filter etalon at the front of the scope. Now there are two etalons present, one internally with the new RichView tuning system and one at the front of the scope with the T-Max tuning system.

"Double Stacking" the etalons improves the scopes resolution by reducing the already narrow <.7 angstrom bandpass to an even narrower <.5 angstrom bandpass. With this set up, the enhanced resolution and contrast will offer a view of the sun that is absolutely stunning.

The "double stacked" system works the same as a non "double stacked" system, the only difference is that now it's a three part system. The telescope body incorporates a tunable sub-aperture etalon in its body as well as a removable etalon on the front of the scope. These tunable etalons works in conjunction with a 15mm blocking filter situated in the solar telescopes 1.25" star diagonal. Together these elements produce a < .5 Angstrom passband which yields an optimal balance of prominence and surface detail.

Celestron 21041 60mm PowerSeeker Telescope

Celestron 21041 60mm PowerSeeker Telescope

• Affordable telescope for beginning astronomer; portable yet powerful
• All-glass optical components with high transmission coatings for enhanced image brightness and clarity
• Refractor optical design with a 60mm aperture and 700mm focal length
• Altazimuth mount suitable for terrestial viewing as well as astronomical use
• Includes 3x Barlow Lens (1.25"), 20mm eyepiece, 4mm eyepiece, aluminum tripod with accessory tray

Offering exceptional value, these telescopes feature portable yet powerful designs with ample optical performance to excite any newcomer to the world of amateur astronomy. Celestron's value priced PowerSeeker 60 is an affordable entry level telescope with some nice extras like a correct image prism and "The Sky" astronomy software included. The package also includes an Alt-Azimuth mount with adjustable aluminum tripod, high and low power eyepieces, a 3X barlow lens, and a 5 power cross hair finder scope.

The PowerSeeker 60AZ comes disassembled in a compact box, but the fully illustrated quick set-up guide makes it easy to assemble. Go ahead and try it out in the daytime, that's the best time to align the finder scope while looking at a distant tree or telephone pole.

The optics of the PowerSeeker 60AZ are surprisingly good, especially when I use the low power 20mm eyepiece. The correct image prism and the 20mm eyepiece give me a magnification of 35X, so backyard birds seem five times closer than with my seven power binoculars. My first view of Saturn's rings and globular cluster M13 in the constellation Hercules came with a 60mm telescope similar to the PowerSeeker 60, and the new PowerSeeker 60AZ is just as good showing me literally hundreds of craters on the Moon.

The PowerSeeker 60 can be upgraded with standard 1.25 inch telescope eyepieces. A 25mm plossl eyepiece for example gives a true field of view of almost 2 degrees for delightful views of star clusters like the Pleiades, while a 6mm eyepiece provides a magnification of 117X, just right to see the rings of Saturn or the cloud bands on Jupiter. The Alt-Azimuth mount included with the PowerSeeker 60AZ is lighter and easier to use than an Equatorial mount, but it does not track stars and planets. As soon as you get the Moon centered in the eyepiece it starts drifting toward the edge, this is caused by rotation of the Earth. The Moon may stay in the low power eyepiece for two or three minutes, but with the high power 4mm eyepiece (175X magnification) a star will disappear in only twenty or thirty seconds.

Celestron's PowerSeeker 60AZ is a real value because it has surprisingly good optics in a package that's light, portable and affordable. The drawback is that it has a lot of plastic parts, including the finder scope and the 3X barlow. For a more rugged alternative, take a look at Celestron's AstroMaster 70AZ which has more powerful optics, better eyepieces, and a much sturdier Alt-Azimuth mount. --Jeff Phillips

• Surprisingly good optics
• Correct image prism
• Easy no tool set-up

Get better pictures from your digital SLR with this Nikon USA: AF-S Micro-NIKKOR 60mm f/2.8G ED lens. With its two aspherical lens elements, lens aberrations are rare. And if you need to take a picture fast, the Silent Wave Motor produces high-speed and quiet autofocus operation. And its Nano Crystal Coat eliminates most internal reflections across a wide range of wavelengths for even greater image integrity. Faster, smoother autofocusing and eliminates barrel length changes and front element rotation Virtually eliminates internal reflections across a wide range of wavelengths Superior color performance, while substantially reducing ghosting and flare Optimized for edge-to-edge sharpness on both the Nikon FX-format (23.9 x 36mm) and DX-format image sensors Rounded 9-blade diaphragm for more natural appearance of out-of-focus image elements M/A Focus Mode allows fast, smooth transitions, autofocus to manual operation Focal length - 60mm Maximum aperture - f/2.8 Minimum aperture - f/32 Lens construction - 12 elements in 9 groups (with one ED glass lens, two aspherical lenses, one with Nano Crystal Coat) Picture angle - 39 40' (26 30' with Nikon DX format) Closest focus distance - 0.185 m/0.6 ft.

The lens is equipped with an exclusive Silent Wave Motor (SWM) that enables accurate, quiet, high-speed autofocus operation. The lens's pair of aspherical elements, meanwhile, virtually eliminate coma and other types of aberration even at the widest aperture. Add in an extra-low-dispersion (ED) glass element--which effectively minimizes chromatic aberration--and your photos will enjoy superior sharpness and color correction regardless of the subject. Other details include an internal focusing (IF) design that enables the use of polarizers and speed-light systems; a Nano Crystal Coat that virtually eliminates reflections across a wide range of wavelengths for even greater image integrity; a Super Integrated Coating (SIC) that substantially reduces ghosting and flare; a rounded nine-blade diaphragm that makes out-of-focus image elements appear more natural; and a M/A focus mode that allows you to quickly transition between autofocus and manual operation.
