Saturn and Mars Photos
images of Saturn and Mars were taken on April 7, 2012, here in Erie, PA.
The sky was very clear, winds slight. The nearly full moon had not risen
above the eastern horizon yet when the Mars photos was taken, but was about
5-10° above the southeastern tree line when Saturn was imaged. Mars was
high in the sky, about 10° east of due south. Saturn was still pretty low
at only maybe 30-35° above the southeastern horizon.
are open close to their maximum due to its orbital position relative to
Earth. There are times when we see the rings edge-on and they are barely
detectable. In the Mars photo, you can clearly see the brighter polar ice
caps that appear to make the planet bulge.
Sometime in late May or
Early June, Saturn will be high in the sky, so I'll try again then. The
city of Erie is to the east, so seeing conditions there are notably worse
than points south and west. Images have consistently turned out much better
when recorder in the south - southwest region of the sky. I attribute the
blue hue in Saturn to the thick atmosphere in the lower SE sky.
Celestron NexImage was used with a 2x Barlow lens in my Celestron 8SE telescope.
The photo is a composite of about 100 short time exposure images recorded
at 5 fps. This really helped avoid atmospheric scintillation. RegiStax v2
software was used.
The 8SE was sitting on its standard tripod in
alt-az mode. The alignment was exceptionally good, with images remaining
within the field of view at the high magnification of the NexImage + 2x
Barlow for more than 15 minutes at a time with no guiding.
Even during the busiest times of my life I have endeavored to maintain
some form of model building activity. This site has been created to help me chronicle my journey
through a lifelong involvement in model aviation, which
all began in Mayo, MD. There
is a lot of good information and there are lot
of pictures throughout the website that you will probably find useful, and might
even bring back some old memories from your own days of yore. The website began life around
1996 as an EarthLink screen name of ModelAirplanes, and quickly grew to where more server
