Meade 10-Inch LX200-ACF (f/10) Advanced Coma-Free Telescope

Meade 10-Inch LX200-ACF (f/10) Advanced Coma-Free Telescope Reviews


Other Picture


Meade 10-Inch LX200-ACF (f/10) Advanced Coma-Free Telescope Feature

  • f/10 Advanced Coma-Free Optics: Building from a classic RC design, Meade has created a new design with the same coma-free pinpoint star images and flatter field also reduces the astigmatism and eliminates diffractions spikes found in classical RCs
  • Meade Ultra-High Transmission Coatings (UHTC) increases total light transmission and image brightness by nearly 20% over Meade's standard coatings. Objects such as stars, galaxies and nebulae will appear significantly brighter
  • Zero Image-Shift Microfocuser allows you to obtain precise image focus with no image movement
  • Oversize Primary Mirror diameters are greater than their listed aperture. This additional 1/4" yields a wide, fully illuminated field-of-view
  • Primary Mirror Lock locks the mirror in place preventing movement during long-exposure astrophotography
Aperture: 10-Inch. Focal Length: 2500mm. Focal Ratio: f/10. UHTC coatings, Standard Field Tripod, 1.25-Inch Diagonal Prism, 26mm Series 4000 Super Plössl Eyepiece. The most widely used research quality telescope now features the most advanced optical system. Meade’s LX200-ACF brings Advanced Coma-Free (ACF) optics within reach of aspiring astronomers everywhere. Nearly every observatory reflector in the world uses an aplanatic (coma-free) optical system like the Ritchey-Chrétien (RC), including NASA’s Hubble Space Telescope. Now you can own similar optics to what the professionals use. The LX200-ACF includes all the field-proven features of the LX200 including GPS, Primary Mirror Lock, Oversized Primary Mirror, SmartDrive; Smart Mount, AutoStar II and more. The new LX200-ACF. It’s the biggest news in astronomy since, well, the LX200.The “advanced” in Advanced Coma-Free. A traditional Ritchey-Chrétien (RC) is a type of reflector that delivers a coma-free, flat field of view via hyperbolic primary and secondary mirrors. Because the mirrors in these telescopes have always been very expensive to make, few amateur astronomers could enjoy them. Fortunately, Meade engineers developed a radical new Advanced Coma Free design by combining a hyperbolic secondary mirror with a corrector-lens-and-spherical-primary-mirror combination that performs as one hyperbolic element. This ACF design produces a coma-free, flat field of view that rivals traditional RC telescopes at a fraction of the cost. The design even eliminates diffraction spikes and improves astigmatism, both of which are inherent in the traditional RC design. When reviewing Meade’s LX200-ACF Advanced Coma Free, Sky and Telescope magazine said, “ [It] does indeed perform like a [Ritchey-Chrétien]. The difference between the off-axis images (compared to a Schmidt-Cassegrain) was dramatic to say the least.”

Vixen 2632 VC200L Telescope Reviews


Other Picture


Vixen 2632 VC200L Telescope Feature

  • 7x50 Finder & Bracket
  • Dovetail Plate and Tube Rings
  • Astophographer's Dream Telescope
  • Made in Japan
Vixen's unique catadioptric design features a high precision sixth order aspherical primary mirror, a convex secondary mirror and triplet corrector lens. VISAC is an abbreviation for Vixen's Six-Order Aspherical Cassegrain. The primary mirror is held by a retaining ring, instead of hooks to decrease flare and enhance contrast.The VC 200L is an 8" f/9.0 highly corrected, highly specialized telescope for astro imaging. The VISAC provides high-definition star images to the edge of a wide viewing field and offers exceptionally outstanding performance in astrophotography.Even at the edge of the 35mm film format (larger CCD chips) stars are sharp ( smaller than 15 micrometers) This is smaller than the resolution of fine quality CCD cameras, which means that the telescope does not limit the image quality.With its elaborate aspherical optical design it achieves an excellent image correction throughout the large illuminated field. (42mm diameter fully illuminated)With the f/6.4 reducer you get much shorter exposure times. The reducer is a highly recommended optional accessory.

Celestron 21041 60mm PowerSeeker Telescope

Celestron 21041 60mm PowerSeeker Telescope Reviews


Other Picture


Celestron 21041 60mm PowerSeeker Telescope Feature

  • 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
Celestron's value priced Powerseeker 60 telescope takes a basic "just the facts" approach to affordable entry level telescopes. The package includes an adjustable aluminum tripod with an alt-azimuth mount and stabilizer, a Kellner type K20 eyepiece, a Ramsden type SR4 eyepiece, a 3x barlow lens, and a 5 power cross-hair finder scope.

The Powerseeker 60 comes disassembled in a compact box, but it won't take long to put everything together. 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.

My first view of Saturn's rings and star cluster M13 in Hercules came with a 60mm telescope, and I enjoy celestial viewing with the Powerseeker 60 to this day. The secret is to use the low power K20 eyepiece and only extend the tripod legs half-way. This gives me sharp and steady views, whether I'm looking at nearby hills, craters on the Moon, the Double Cluster in Perseus, or even the Andromeda Galaxy!

With a 1.25" focuser and diagonal mirror, it's easy to add better eyepieces. The Kellner type K20 eyepiece yields a 1.1 degree true field of view, better than the Huygens or H-type eyepieces still found in many beginner scopes. Adding an optional Celestron 25mm E-Lux eyepiece is better still. With nearly 2 degrees true field of view, the 25mm E-lux makes it much easier to find objects, either on land or in deep space. The SR4 eyepiece is less impressive; it's like peeking through a pin-hole. Adding the 3x barlow to the SR4 to get that 525x proclaimed on the box is peeking through a dim, fuzzy pin-hole.

I'm surprised that a telescope this inexpensive can be this good. It's good enough to show me Saturn's rings at night or a Steller's Jay at 100 yards during the day. In my opinion, the Powerseeker 60 would be an even better bargain if it came with a K10 eyepiece in place of the 3x barlow and the SR4 eyepiece. Also take a look at Celestron's Firstscope 60AZ; it's only a little more expensive, but it includes two useable eyepieces, a red-dot finder, and planetarium software for your computer. –Jeff Phillips

Pros:

  • Low cost
  • Decent optics
  • Accepts 1.25" eyepieces
Cons:
  • Too small for serious astronomy
  • Only one good eyepiece

The PowerSeekers come with all coated glass optical components with for enhanced image brightness and clarity. The Newtonian reflectors offer larger aperture and greater light gathering power needed to resolve the faint detail of hundreds of deep-sky and other celestial objects.

All PowerSeekers come on either sturdy equatorial mounts for tracking the sky, or collapsible altazimuth mounts suitable for terrestrial viewing as well as astronomical use.

The PowerSeekers come with a full range of eyepieces plus a 3x Barlow lens, allowing an increase in viewing power hundreds of times greater than that of an unaided eye!
