Star Party 02/01/2003
Star Party, Feb 2, 2003
There are 12 exposures using a red filter over the flash. Each of the twelve exposures were metered at F5.6 @ 30”, so if you do the math, the full time exposure is six minutes. During that time, Tom walked around flashing everyone. The last two exposures were flashed with a green filter. Tom also made triangles and circles and even an infinity sign using his flashlight behind the red and green filters here and there in the photograph. It is notable that it looks so bright, even though it was done in almost total darkness, you can even see a couple of jets in the background with their blinking lights. People were moving around during the exposures. People even moved their telescopes. Don’t forget – everyone in the photograph has their eyes closed!

MDAS members stayed all night atop Mt Diablo to watch the meteor shower. This picture was made by simply keeping the shutter open for a couple of hours. No meteors were caught
Sun Spots
Sunspots on August 26, 2001
Attached the camera to a five inch telescope and captured the activities on the Sun. Radio static predicted sunspot activity that day and the picture proves why.
Spots closeup
The large spot a little closer
This close-up was taken by putting a Barlow lens in the telescope. This spot group is interesting because there is a small spot in the big spot. Can you see it?

Another image taken with my camera held up to an eyepiece, this time it was daylight, and the telescope was equipped with an H-Alpha filter. Notice the prominences in the upper-right and central-right portions of the image.
