Orion Observer 70mm Equatorial Refractor Telescope


Orion Observer 70mm Equatorial Refractor Telescope
  • A great entry-level refractor telescope at a very affordable price
  • Reveals detailed views of the Moon and bright planets such as Jupiter and Saturn
  • 70mm (2.75") aperture and 700mm focal length provides great views of bright night-sky objects
  • Includes sturdy tripod and equatorial (EQ) mount for convenient manual slow-motion tracking of celestial objects
  • Includes two eyepieces, finder scope, focuser, 90-degree mirror diagonal for comfortable viewing
  • Free Starry Night astronomy software and DVD, and more!

This tried-and-true refractor goes the extra distance in introducing the novice to the wonders of the night sky. The Observer 70 features a 70mm fully anti-reflection coated achromatic objective lens, which provides 36% more light-gathering ability than a 60mm. Its 700mm focal length (f/10) will show you the stark beauty of the lunar surface, Saturn's rings, Jupiter's atmospheric belts, or the billowy clouds of the Orion Nebula. The included EQ-1 equatorial mount comes equipped with dual slow-motion controls for manual star tracking and adjustable aluminum tripod. Includes an EZ Finder II finder scope to help you zero in on your celestial targets, two eyepieces - 25mm (1.25") and 10mm (1.25") - and 90-deg star diagonal. One year limited warranty.

Celestron 21045 114mm Equatorial PowerSeeker Telescope Reviews

Celestron 21045 114mm Equatorial PowerSeeker Telescope


Celestron 21045 114mm Equatorial PowerSeeker Telescope
  • Affordable telescope for beginning astronomer; portable yet powerful
  • All-glass optical components with high transmission coatings for enhanced image brighness and clarity
  • Newtonian optical design with a 114mm aperture and 900mm focal length
  • Equatorial mount for tracking the sky
  • Includes 3x Barlow Lens (1.25"), 20mm eyepiece, 4mm eyepiece, aluminum tripod with accessory tray

Celestron PowerSeeker 114EQ 45 - 225X Reflector Telescope opens up the wonders of the universe to the aspiring astronomer. Amateur astronomy is a great hobby you can enjoy year-round, and Celestron's PowerSeeker Telescopes are the ideal choice for affordable stargazing enjoyment! PowerSeeker Scopes are quick and easy to set up, even for the novice... no tools required! Their sturdy Equatorial mounts are perfect for tracking objects across the night sky, meaning these Telescopes shine for moon- and planet-watching. All Celestron PowerSeekers include a tripod, full range of eyepieces, plus a 3X barlow lens. Specs: 114 mm aperture size; Includes 20 mm eyepiece for 45X magnification, 4 mm eyepiece for 225X, and a 3X barlow lens that triples the magnification power of each eyepiece; Newtonian reflector optical design; Fully-coated glass optics with high-transmission coatings for enhanced brightness and clarity; Sturdy German Equatorial mount, perfect for tracking objects across the night sky; Erect image diagonal, ideal for terrestrial and astronomical viewing; Comes with The Sky X Planetarium software; Focal length: 900 mm; Limiting stellar magnitude: 12.8; Resolution (Rayleigh): 1.22 arcsec; Resolution (Dawes): 1.02 arcsec; Light-gathering power: 265X; Angular F.O.V. is 0.9 degrees. Linear F.O.V. is 48' 5x24 mm finderscope; Includes aluminum tripod. Order yours today! Celestron PowerSeeker 114EQ 45X-225X Reflector Telescope I love bargains, so I was eager to try out Celestron's new Powerseeker 114 Newtonian reflector telescope. With its 4.5-inch mirror, Celestron's Powerseeker 114 gathers three times more starlight than popular 60mm refractors. The Powerseeker package includes two eyepieces (K20 and SR4), a plastic 3x barlow, and a lightweight equatorial mount.

Optically, the Powerseeker 114 holds its own when compared with my Celestron Firstscope 114EQ. Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x. I find a collimation tool helps get this fine tuning just right.

As good as the optics are, however, the effect of cost-cutting shows up in the mechanical components. The focuser is plastic, the finder scope is plastic, the rings that attach the telescope to the tripod are plastic. Even when the tripod legs are clamped at their shortest setting, the telescope wobbles when I try to focus at higher magnifications. Celestron's instruction manual correctly recommends that most viewing be done in the range of 40x to 130x. So what about that 675x magnification proclaimed on the box? I'd say it's not worth the trouble.

Overall, the Celestron Powerseeker 114 is a budget priced telescope with good optical performance, especially when using the low power K20 eyepiece. If you're willing to spend a little more money, either Orion's SkyQuest XT4.5 or Celestron's Firstscope 114EQ will give you a sturdier mount, an improved finder scope, and better eyepieces. Also, for about the price of the Powerseeker 114, I like the dependable refractor design of Celestron's Firstscope 70EQ. --Jeff Phillips

Pros:

  • Low cost
  • Good optics
  • Serviceable K20 eyepiece
Cons:
  • Wobbly mount
  • Difficult to collimate
  • Plastic finder and focuser

  • Orion SpaceProbe 3 Equatorial Reflector Telescope

Buying a first telescope used to be risky business, with more cheap models on the market than affordable quality ones. Our SpaceProbe 3 changes all that. It's not only affordable, but its optical quality will make the night sky's treasures accessible right from your backyard. The 3"-diameter primary mirror gathers enough light to reveal the faint glows of many star clusters and nebulas, as well as Saturn's rings, Jupiter's moons, and the stark, cratered terrain of the Moon. The aluminum Newtonian optical tube features a 1.25" rack-and-pinion focuser and two Explorer II eyepieces - a 25mm (28x) and a 10mm (70x). The included EZ Finder II finder scope helps you locate objects with ease. The SpaceProbe 3 EQ's equatorial mount allows easy manual "tracking" of objects with the turn of a knob (or use an electronic drive, sold separately, for hands-free tracking). Includes aluminum tripod with accessory tray.

  • Orion SpaceProbe 130ST EQ (307 x 130mm) Telescope

The SpaceProbe 130ST EQ is a rich-field Newtonian reflector with a tube only 24" long compared to the 33" tube length of the standard 130 EQ. The focal length of the ST's 130mm (5.1") primary mirror is 650mm (f/5), producing a wider field of view and brighter images for a given eyepiece focal length. The diffraction-limited parabolic primary mirror is the same type used on much larger reflectors costing substantially more. On a short-focal-length design like this one, a parabolic mirror is a must for delivering sharp, detailed images. This scope package includes an EQ-2 equatorial mount with dual setting circles and manual slow-motion controls, adjustable aluminum tripod with accessory tray, two Plossl eyepieces (25mm and 10mm), and a 6x30 achromatic finder scope. One-year limited warranty.
