Tonight NASA's solar sail satellite passed over Tucson at 7:35pm. A difficult object to see as it is realively small. I decided to try and capture it "on film" (well - with my digital camera). Because the event happened in late twilight, lasted only 60 seconds (for the field of view I chose) and I was imaging from my light polluted house - exposures had to be made at high ISO (to ensure capture of the satellite) and threrefore realtively short (as not to overexpose the bright sky background).
Below is the result - NanosailD is the dashed diagonal line running from top-center to bottom left. The trail appears dashed because this image is actually a combination of 15 four second exposures with a one second gap between exposures. the NanosailD trail is but one of 6 satellites captured in the 60 seconds worth of exposures - can you find them?
