star tracking telescope flights and photography?
Can you share with me somehow set myself up with a telescope ecconomical flight tracking flights and also be able to take long exposure photos?
Geoff's response is a good choice for a low-cost approach for astrophotography assuming that you are very good to build one. When it comes to commercial equipment astrophotograpjy, the problem is that not a cheap hobby. Astrophotography team has become much more affordable in recent years but still need to spend over $ 1000 just for starters. The most important part of astrophography is Mt. low cost tracking mounts, such as those sold by Orion, Celestron and Meade are good for photography short exposure (up to a couple of minutes), but inadequate for long exposures. This is due to good monitoring requires high quality and mechanical precision, and this comes at a cost. Self-guided help but not completely replace the need of good mechanical quality, and requires additional equipment, which increases the cost. If you really want to try long exposure astrophotography, Vixen (GP, GP Do Sphinx) or Losmandy are probably the lowest cost is fitted with mechanical quality enough to make a coherent work. Engines / controls all north coast of $ 1500.

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 Features

Celestron 21062 AstroMaster 70 EQ Refractor Telescope
List Price: |
DescriptionIf you're looking for a dual-purpose telescope appropriate for both terrestrial and celestial viewing, then the AstroMaster Series is for you. Each AstroMaster model is capable of giving correct views of land and sky. The AstroMaster Series produce bright, clear images of the Moon and planets. It is easy to see the moons of Jupiter and the rings of Saturn with every one of these fine instruments. For views of the brighter deep space objects like galaxies and nebulae, we recommend the larger aperture and light gathering ability of the Newtonian reflectors. Celestron’s AstroMaster 70 EQ combines the solid optical performance of a classic achromatic refractor with a German style equatorial mount. The Astromaster 70 features easy no-tool setup and much better optics than 60mm beginner scopes. The Astromaster package includes high and low power eyepieces, a correct image diagonal prism, illustrated instructions, and planetarium software for your PC. The AstroMaster 70 EQ features very good optical performance. Achromatic refractors have a two piece objective lens, the second lens element compensates for “chromatic aberration”, the false color or blue fringes seen in low cost telescopes. In daylight tests I see very little blue fringing with the standard equipment 10mm eyepiece (90X magnification), and none at all with the 20mm eyepiece (45X). Stars and planets show up very nicely with the AstroMaster 70. The bright double star Castor, one of the “twins” in the constellation Gemini, is cleanly split at 90X with the 10mm eyepiece. When I tried an optional 6mm Plossl eyepiece for a magnification of 150X, I was treated to lovely views of Saturn’s rings and the little orange disk of Mars. My view of the Moon was delightfully crisp and clear; the 20mm eyepiece nicely frames the Lunar disk, and using the 10mm eyepiece I could easily see mountain peaks and terraced walls inside the crater Copernicus. The AstroMaster 70 EQ also features a newly designed tripod with 1.25 inch stainless steel legs. This new tripod holds the telescope firmly; I had no trouble focusing even with a high power eyepiece. The equatorial mount is a little more complicated to balance and align than the AstroMaster 70 AZ , but the reward is better slow motion control and tracking at magnifications over 100X. Simply point the equatorial axis at Polaris, the North Star, and the telescope tracks celestial objects by turning one slow motion knob. This makes it much easier to use a high power eyepiece while viewing the Moon and Planets. The “star pointer” finder scope works by shining a red LED on a plastic window; just look through the window and line up the red spot with your target. This works OK for bright objects like the Moon and planets but not so well for finding galaxies and deep space objects. The AstroMaster 70 EQ is a very good entry level telescope for a student or family. The good quality 70mm optics produce an image that is significantly sharper and brighter than 60mm beginner scopes, and the AstroMaster 70 EQ includes a solid mount, two good eyepieces, and fully illustrated instructions. --Jeff Phillips Pros: Reliable refractor design Good views of the Moon and planets Complete accessory package Simple no tool setup Cons: Star-pointer not so easy to use Features

Orion SpaceProbe 3 Altazimuth Reflector Telescope
Sale Price: $99.99 |
DescriptionIf you're looking for an affordable entry-level telescope for that beginning astronomy enthusiast, our SpaceProbe 3 Altaz is the perfect choice. Great for all-around stargazing, this highly portable, uncomplicated scope is just the right size and weight for the entire family, and just the right price for parents. This is a quality telescope, with a 3" (76mm) glass primary mirror mounted in a sturdy Neptune Blue Metallic aluminum tube. The rack-and-pinion focuser accepts standard 1.25" eyepieces. Two Explorer II eyepieces, a low-power 25mm (28x) and a high-power 10mm (70x), are included. An EZ Finder II finder scope mounted on the tube helps zero-in on the sky target. The altazimuth mount is lightweight and easy to use. To aim it, simply move it up or down or left or right. An adjustable, aluminum tripod with accessory tray is also included. One-year limited warranty. Orion's surprising little Spaceprobe 3 has been picked by independent reviewers as one of the best telescopes in its price class. Unlike similar telescopes seen in discount stores, Orion has refined the Spaceprobe 3 by paying attention to the little details, and that make this telescope a great value. The Spaceprobe 3 comes with an unusually complete set of accessories. The package includes two very good Explorer II eyepieces (25mm and 10mm), an adjustable altazimuth tripod, a good red-dot finder, a student edition of "The Sky" planetarium program, and a well written manual. The package even includes the tools you'll need to assemble the telescope and align the optics. The Spaceprobe 3 is a Newtonian reflector. That means it uses mirrors instead of lenses. Newtonians are primarily used for astronomy because the images are upside-down. Orion includes a collimation tool and good directions for aligning the mirrors. The reward for aligning the mirrors is seen in images that snap into sharp focus. My Spaceprobe 3 arrived properly aligned right out of the box. With its Explorer II eyepieces, this telescope consistently delivers fine views. Using the 25mm eyepiece (28x magnification) the Pleiades cluster is simply wonderful, showing dozens of stars. From a rural location with a dark sky, the Orion Nebula is a big ghostly glow, and when I zoom in with the 10mm eyepiece, the Trapezium resolves into four tiny pinpoints. The double star Gamma Andromeda becomes two beads of light, one gold, the other one pale blue. Moon and planet images are crisp, with none of the false color I see in low cost refractors. When I look at the Moon I see mountains and terraced walls inside the larger craters. With the 10mm eyepiece (about 70x), Saturn's rings are sharply separated from the planet, and I can even pick out the planet's shadow on the rings. The Altazimuth mount included with this telescope is light and easy to use; it may be the best choice for a young astronomer. If you want motorized tracking of the stars and planets, Orion's Spaceprobe 3 EQ is available with an equatorial mount, and Celestron sells essentially the same optical system with the computerized NexStar 76GT. –Jeff Phillips Pros: Best in class optical performance Two good Explorer II eyepieces Complete accessory package Cons: Small 76mm aperture Upside-down terrestrial images Features
