Jupiter and its Moons in the Daytime

NOV 25, 2010

Back in May, I took a picture of Jupiter in the middle of the day. Taking the picture was easy---the tricky part was finding Jupiter.

A few details: I used a level, compass, and the Moon to polar align. Once polar aligned, I could "dial-in" Jupiter's location based on its coordinates I read off from the planetarium program on my laptop (Cartes du Ciel). Given accurate pointing, it was easy to find Jupiter in the eyepiece. I was even able to see Jupiter's cloud bands. But, I didn't notice the GRS or the Jovian moons until I stacked and sharpened the images I acquired as video using a cheap webcam.
