Amateur Astronomy website.
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 was made with
my Canon S1 2S Power Shot, mounted on a tripod. 15-second exposure. 11/6/2007, 11:00
pm est. Through my 8x45 binoculars, comet Holmes appears as a very prominent smudge.
It is easily seen with the naked eye as what looks like an extra star in Perseus.
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.

my pervious house in Erie, PA. I was pretty much buried in trees there.

from immemorial times." - George Ellery Hale
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

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.
Amateur Astronomy Mfgs & Services
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.

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.
