Great capture! 

I experimented with this one night but didn't expose long enough. 

30 second exposures with the DMK and my 10" record stars down to about 19th magnitude.

best,

Alan

Hi,

I thought some of you guys might be interested in this image of Phobos and Deimos. 

Taken with a 9.25" SCT, and a DMK 21BF04 firewire camera in its prime focus. Seeing was 

horrible, so instead of trying to capture surface detail on Mars, I gave this a shot... I was 

surprised how "easy" it was to capture the two little moons, the DMK camera was binned 

2x2, exposures were 1/4 second each, about 200 images stacked. The 21BF04 is a very 

sensitive camera, which continues to amaze me.

The image of Mars was exposed separately and inserted into the overexposed region for 

scale purposes.
