The Sky is a Sphere (Part II)
Following on from "The Sky is a Sphere", these shots of the conjunction of Venus and Saturn are taken around the same time (roughly between 6:00 pm and 6:10 pm ACST), between June 26 and July 3. Naturally you have to click on the image to enlarge it and get the best detail. Gaps are coaused by bad weather.As well as the sky rotating due to time differences between each shot, every night the stars set a little earlier too. I've lined every thing up on Regulus and Algieba but these stars move with respect to the tree in the back yard as well. So even if I did get the pictures all at the same time (and assuming that I got the camera in the right spot each time), the images of the trees would be out of registration.
Still, I'm getting the hang of the Gimps rotation tool, so this lot was easier to assemble than the last. I might make an animation of it.
