Dual Filamentary Structure July 7 2003
The sun was much cooler at 9:30 than after 10AM today!  I was lucky with this sunspot image in that I managed to capture during a brief second of "good" seeing; the other four images of the spot (made during the same session) showed tremendous turbulence.

Crescent Moon Sept. 9, 2002

By Ed Abel in Silver Springs, Md.

99 Image Moon Mosiac by Ed Abel

Of the 113 images taken, I used 23 to make the composite. What was also a challenge was the change in sky brightness between  7:25 and 7:40. This required a change in the brightness level of the individual images used in the composite in order to achieve a consistent light level.  I can appreciate why the Phillips at prime focus on the C-8 can be used only on a crescent moon requiring far fewer individual images!

Dark Skies Are Great But Don't Despair Because You Can't Live in Tucson, Az.!
Here are some images made by observers living near Washington, D.C. and accounts of how they made them. The Universe is up there, we just have to work harder to find it! If you live near Washington, D.C. and would like to share experience astro imaging, or if you have a productive suggestion, the web page owner would be J to hear from you via + to Alpha Siderius
