Hubble captures transit of Saturn's moons

The Hubble telescope has taken some very nice pictures of four of Saturn's moons transiting at once.



Titan is the largest visible at the top. Enceladus, Dione, and their shadows on Saturn are on the left, while Mimas is visible on the right. The moons, Saturn and Earth with the Hubble telescope orbiting it have to be aligned just right to get these images. Someone had to do the calculations of place and time so that Hubble could be pointed at Saturn to catch it.

More pictures and videos are available at the HubbleSite.

Total Lunar Eclipse pictures from northern Delaware

I was able to capture the first half of last night's total lunar eclipse with my camera. The moon was at such a good angle that I didn't have to go outside, which probably contributed to the number of pictures I took, if not to their quality. The angle was so good that if I slept with my head at the foot of my bed I wouldn't have even needed to get up to watch it. That's my kind of astronomy.


Here is a composite of the first half with the moon being covered. The second half with the moon being revealed was after my bedtime. I did change some exposure setting during the eclipse as the moon became less bright, and the last was taken with the tripod finally and was a much longer exposure to bring out the red of the moon. I think they turned out well considering the equipment and the photographer, the next step would be a much more expensive camera, lessons on how to use it, mounted outside on a tripod.



This picture, taken at the height of the eclipse, was taken with an 8 second exposure with me holding the camera as still as possible braced against the window frame. I wanted this one because I couldn't get an angle with the tripod with the moon, Saturn and Regulus from the consetallation Leo all in the same shot so I had to hold the camera myself. I still jiggled a little but you get the gist of it. Saturn is to the left and Regulus above (I think? Any comments or corrections?), click for a bigger picture.

Include links to your lunar eclipse pictures in the comments. Howard was watching too, maybe he has pictures.
