Amateur astronomy is one of those hobbies in which I participated avidly for the four years in the U.S. Air Force and for a couple years after separating. During that time I observed as often as time and atmospheric conditions permitted. While at Robins AFB, in Warner Robins, Georgia, I belonged to the Macon Amateur Astronomy club and spent quite a few Friday evenings operating the museum's/club's 8", 10" and 14" Celestron telescopes both for private observation and for assisting the public after the planetarium show. The club took a couple trips to the Fernbank Science Center in Atlanta and got to look through their 32" reflector, which at the time (circa 1980) was the largest reflecting telescope in the southeast. Today, of course, private 30" Dobsonians are as affordable as motorcycles. A picture of me and my 8" Newtonian reflector is given below. I ended up selling it after getting married to help pay the mortgage (sold all the R/C stuff, too). Only naked-eye (no longer anywhere near my former 20/15 vision) and my trusty binoculars remain for observing over the past 20 years. Recently, have I begun reacquiring some of my "toys" from yesteryear. I have not purchased another telescope yet, but the good thing is that now the state of the art is orders of magnitude better than where I left off.
This photo of the full moon - Mars conjunction (≈3/8°), taken December 23, 2007, captures the northernmost
(highest in the sky) full moon of the year. Earth will pass between Mars and the sun tomorrow. Mars will not come this close to Earth again
until the year 2010.
"Like buried treasures, the outposts of the universe have beckoned to the adventurous from immemorial times." - George Ellery Hale
Here I am (Kirt Blattenberger, webmaster) with my 8" Newtonian reflector, circa 1982. It was purchased used from an astronomy shop in Baltimore, MD. After struggling with dragging out the tripod and doing polar alignments night after night, I finally got smart and built this concrete block pier and ran 120 VAC to it for the clock drive. The pier cap I custom cast out of concrete to mate the equatorial mount to the blocks. Observation nights were greatly increased in number after doing so. The finder is a piggybacked 2" Tasco refractor. I made a remote focusing mount for the eyepiece using a servo from one of my other hobbies - model airplanes and rockets. Soon, I will scan and post some of the photos I took with it using my Minolta SLR. There were no digital cameras in those days.
Skip ahead nearly three decades, and here I am in my back yard in Erie, Pennsylvania, "playing" with my newly acquired (in June) Celestron NexStar 8SE telescope. City lights are fairly bright here to the east and west, but farm land is to the south and Lake Erie begins two miles to the north, so that limits the light pollution somewhat. Erie is not that large of a city, so that also helps. Still, compared to the truly dark skies in areas I have lived in Vermont and Colorado, the seeing is noticeably bad. I haven't had a chance to try any of the filters that came with the eyepiece and filter kit that came with the scope.
To the left is more recent image (2/9/2012) of Jupiter. I'm getting a little better. The sky was exceptionally clear, winds nonexistent, and the nearly full moon had not risen above the eastern horizon yet. Jupiter was about 15° west of due south, high in the sky. My Celestron NexImage was used with a 2x Barlow lens. The photo is a composite of about 500 short time exposure images recorded at 5 fps. This really helped avoid atmospheric scintillation. If I had done a better job on the focus, the detail might have been even better. RegiStax v2 software was used.
To the right is my first ever image of Venus.
Greenbelt, MD Specializes in archiving and distributing collections of data that have been published by professional astronomers. Most of these data sets are in the form of computer-readable tables of numbers, rather than images. Amateur astronomers can find these data collections useful in looking up the properties and locations of celestial objects. This can help amateurs plan for observing sessions, and help them to better understand what they've observed.

Spitzer Space Telescope
818-354-4200 / Pasadena, CA
The Spitzer Space Telescope (formerly SIRTF, the Space Infrared Telescope Facility) was launched into space by a Delta rocket from Cape Canaveral on 25 August 2003. Spitzer will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space between wavelengths of 3 and 180 microns (1 micron is one-millionth of a meter). Consisting of a 0.85-meter telescope and three cryogenically-cooled science instruments, Spitzer is the largest infrared telescope ever launched into space.
