Just took delivery of my new 300mm f/4 lens and was testing sharpness and focus at night. Did not expect much from taking photo of the planet but focus was instant and resulting image was a surprise. Nikon D7000 300mm F/4 with 1,4x converter on tripod. AF-s Single, F/8, 1/150s Manual mode, Matrix metering, ISO 100. Original image was just small a small dot and was zoomed in and cropped.
Jupiter is at the moment in the ideal position for photography. I tried again last night but it was not as good. Could be humidity in the air. Strange my first shot ever was the best and I was not able to repeat it and it was taken only in jpg.
I am having lot of fun with my new lens. This is combined image over several days with changing moons position. Not until all the moons were on one side that I was able to name them. Io is photographing orange to brown when not overexposed. Callisto is the least bright. Note Io is just visible going around Jupiter Moon shot was used as size comparison. I know it is not much for Astrophotography blog but it has been fun.
