Ok, this is my very first time to try photographing something like Jupiter. I have done a little with the Milky Way, but that was actually fairly straight forward because I had time to plan and research.
This shot of Jupiter was one of those spur of the moment shots. Actually, this is a composite of two shots so that I could get a properly exposed planet and three moons in the same shot. Jupiter was low to the horizon, so I would have been better off if I had waited until later in the evening, but, again, this was just a shot that came from a conversation that went like this:
Friend: "Hey, I wonder what that star is?"
Me: "Dunno, can someone check an app?"
Friend (checking app): "It is Jupiter."
Me: "Cool. Let me see if I can get a shot of it and see how it comes out."
I could see the moons on my camera screen, but I didn't know that I could see the bands on Jupiter until I looked at the photos on my computer screen. The two photos were cropped close to 100% and combined in Photoshop Elements.
