2010/12/20 Total Lunar Eclipse

It has been a really stormy Dec, I have not even seen a trace of blue sky for at least 2 weeks prior to the eclipse. When I checked weather forecast a week before the event, all I could see was rainy/overcast. Nobody in bay area had any hope to view this eclipse. However a quick and strong winter storm plowed through bay area right before eclipse started, left much needed cloudy sky to view the event, before the next storm moved in.

Since weather was most cloudy and there was still occasional a few drops of rain, I set up my scope and mount in my backyard for quick observation. The Moon was completely blocked around the greatest eclipse, but the sky was clear from time to time for the rest of totality, which allowed me to take pictures of colorful Moon over starry sky.

This composite is consisted of 18 images throughout the eclipse.

This composite shows the change of the brightness and color of the Moon, prior to and throughout the totality. The exposure of each image is 1s @ ISO 800.

This 10-pane composite shows crescent shape of the Moon while approaching the 2nd contact.

This composite shows turquoise color seen during the eclipse. The exposure of each image is 1/5s @ ISO800.

This is a very special image, which I took just by fortune. The moon was about to occult a double star XZ33749 (just below the Moon), whose primary is 9.53m and secondary is 9.8m, 8.9″ apart.

2015/04/04 Total Lunar Eclipse

This is the third of a series of 4 consecutive total lunar eclipses visible from US in year 2014 and 2015. This is also a very special total eclipse, not because the Moon set shortly after the eclipse was over viewed at San Jose (so you could see Red Moon twice at that night), but it is the shortest total eclipse in almost 5 centuries. However some believe that it might just a partial eclipse as the Moon seemed never get dark.

Since the Moon was going to set right after 4th contact, I went to Henry Coe State Park for its wide open western horizon. The weather was clear entire night, though there might have been one or two very thin high clouds passed by.

This composite is consisted of 21 images throughout the eclipse.

This composite shows turquoise color seen during the eclipse. The exposure of each image is 2.5s @ ISO200.

This 26-pane composite shows the shape of the Moon while approaching the 2nd contact.

This composite shows the change of the brightness and color of the Moon, prior to and throughout the totality. From this composite, you can see that the moon always has some bright portion even within totality. The exposure of each image is 5s @ ISO 200.
