Star-test results apply to the complete imaging performance of the telescope. The star test is lightning-fast and requires only a good high-power eyepiece. It tests the telescope for precisely what it was meant to do. Bad or poorly-aligned instruments fail the star test unambiguously. The star test often allows you to correct the optical difficulty immediately in the field, when you might be frantic to have your telescope perform well to observe a once in a lifetime event. Star Testing Astronomical Telescopes as a guide, your telescope will perform to the best of it's abilities and perhaps it will show images better than you would have believed possible. From The Reviewers Far too many of us have experienced this disturbing scenario. But now, thanks to Star Testing , you can answer these questions easily and probably have the telescope operating in no time. And if there is an optical problem, you will be able to communicate it clearly to the dealer and get prompt action. Chapter One and Two explain basic optics in a fashion that any motivated beginner can follow. Computer-generated illustrations of defocused star images are so realistic that you can learn a great deal by just looking at the pictures . . .

Bill Keel's Telescope Life List Iridium flare over Kitt Peak. telescopes I ve Used (and what I ve done with them). I admit it I ma telescope junkie. Backyard, mountaintop http://www.astr.ua.edu/keel/telescopes/
Extractions: I admit it - I'm a telescope junkie. Backyard, mountaintop, optical, infrared, orbiting, any flavor. I do have the good fortune to be in a profession that doesn't consider this too much of an aberration. To show what kinds of projects can be done with various instruments (at least the kinds I've thought of), here's a gallery of observatories and telescopes I've used with some sample data and results. Since astrophysics now has (and needs) access to much of the electromagnetic spectrum, there are optical, infrared, radio, ultraviolet, and X-ray facilities to be found. For each picture, a click will get you the full-sized version. There is a mix of pictures of and data through each telescope. Where one exists, I've included links to the "official" WWW sites for these instruments, and to the TerraServer overhead imagery. Some of the USGS images are included here. Some images are still to be added, and all the listed sites will eventually have their own information and image pages. About the picture above: this 30-second exposure taken on 20 December 1999 shows a brilliant flare (visual magnitude about -6) from the Iridium 62 satellite seen over Kitt Peak , as viewed from MDM Observatory . Lyra is rising in the background with Vega at left. More information on Iridium flares (and other satellite viewing opportunities) may be found at the Heavens-Above site , especially now that the future of the Iridium communications constellation is in less doubt than before.

The Committee is delighted to announce an affiliation with Double Agent Records and one of the greatest-ever British bands, The Telescopes, with a compilation of this prolific band's best work, now all out of print (and all of it previously unreleased in the USA). Download the song "Flying" "Like mad cultural terrorists, they've taken the norm and fed it through a psychedelic blender. It's all rather jagged and unsettling, the musical equivalent of cackling maggots spilling out through the eyeholes of the beautiful- and is both timely and exciting" (Melody Maker, 1994) The Bio Part of the British shoegazing movement given impetus by the Jesus and Mary Chain and spearheaded by My Bloody Valentine, the Telescopes' sound borrowed from those two bands while adding their own garage punk flavor. Based in Burton-upon-Trent, England, the Telescopes consisted of vocalist Stephen Lawrie, guitarist Joanna Doran, guitarist David Fitzgerald, bassist Robert Brooks, and drummer Dominic Dillon. They made their debut on a couple of independent singles and the 1989 EP 7th # Disaster , and then switched to the What Goes On label for two more EPs and a full-length debut, Taste , that same year, experimenting with violins, trumpets, and dynamic contrasts.

Astronomy clubs and associations, universities, planetariums and so on, host events designed to highlight what it is about stargazing that has them hooked. The idea is that by showing people in their area the resources and facilities on their doorsteps, more people will get involved. Since it began in 1973, Astronomy Day has been chosen so that it falls near or before the 1st quarter Moon. This is the best time for observing stars, as the sky is darker without the moon's reflected sunlight. Andromeda galaxy home to ten black holes

Extractions: TELESCOPES IN GENERAL: A telescope has two main functions: (1) to gather and focus a large amount of light from an object (much more than the eye alone can) to form an image of the object, and (2) to magnify that image so that distant objects can be better seen. There are many different designs of telescope that will accomplish these functions but only two designs are practical for small inexpensive telescopes: the refractor and the Newtonian Reflector. A refractor (figure A) focuses light by "refracting" or bending it through a special two element glass lens. A reflector (figure B) focuses light by reflecting it off a curved mirror. A set of lenses known as the Eyepiece then magnifies the focused image in each design. There is a catch to using high power! Higher magnification, while making the object appear larger, spreads out the light gathered by the telescope over a larger area resulting in a fainter image. Also, because of the restrictions imposed on eyepiece design, you may only see part of that big image due to the smaller "field of view" high powers give you. Very long f-ratio telescopes can give you higher power with a given eyepiece, but you may not be getting much out of those powers if the light is too spread out. You have to compromise to get the best results. At this time we must cover a very important point:

As a kid, I had fallen in love with the 200" Palomar scope. Since my dad worked in home building, I used wood. Here's a sketch from the side, and a sketch of the yoke. My next home built scope - a 10" f/5. I built my own drive using wood putty to form the impressions and a metal threaded rod attached to the motor. Because many threads were in contact at any one time, errors in the threads were averaged and there was no backlash. Here are sketches of the fork arms base , and cradle . I built a cold camera (here's a sketch ) to take long exposure astrophotographs at prime focus of the 10". For more on the 10", see April, '79 Sky and Telescope.

Extractions: Printable Version The following timeline covers the early history of Palomar Observatory, from its conception in the early 1900's, through the 200-inch's twenty-one years of construction until it began full-time observing in 1949. All images except the last one ( Caltech Archives . Click on any image to enlarge. 1908: Mt. Wilson 60-inch telescope Under the supervision of George Ellery Hale, and through grants from the Carnegie Institution of Washington, the Mount Wilson 60-inch telescope is completed and sees "first light." It is the world's largest telescope, and with the exceptionally calm and stable atmosphere above the Los Angeles basin, astronomers can see fainter and more distant objects than ever before. Harlow Shapley uses this telescope to measure the size of our galaxy (the Milky Way) and the solar system's position in it. 1917: Mt. Wilson 100-inch telescope While the 60-inch is constructed, Hale and the Carnegie Institution plan a yet larger design. Despite technical challenges in casting and shaping the glass mirror, and difficulties with funding, the 100-inch telescope is completed in 1917. It is a temperamental machine - the large mirror is highly sensitive to temperature variations which cause it to go out of focus easily. Despite such problems, it provides an unparalleled view of the faraway universe. Edwin Hubble uses this instrument to determine the distances and velocities of neighboring galaxies, demonstrating that they are separate "island universes" and not small nebulae contained within the Milky Way, as many astronomers had previously thought. He also discovers the first indications that the universe is expanding. Measurements of more distant galaxies, and fine details of the near ones, are still beyond the reach of the 100-inch.
