Forums Mercury Transit of Mercury Composite


Finally managed to find the time (many hours) to get my head around PhotoShop (with help from David Basey) to make a composite image of my images showing the transit from Monday, as view from Nottingham. It was blowing a gale here and there was intermittant heavy cloud, but I was taking an image every 20 seconds during the transit so have managed to find a reasonable image about every 15 minutes which I’ve superimposed onto the first image where Mercury just starts to take a bite out of the Sun. I’ve had to crop the planet everso slightly as the background intensity of the Sun differed grealy between the images, so the planet too perfectly round I’m afaraid, but its position is as close I could get it using the whole face of the Sun to position each one; I suspect the slight wobble on the planets track is due to movement in my set up and camera in the gale, but I felt this was more realistic than making a false straight line which my data doesn’t support. I’ve nearly given up with the time lapse video as the cloud after the first five hours just makes stacking the frames nearly impossible, but if I can face wasting another 6 hours on it I will try again.
