Pluto Blink Animation à la Clyde Tombaugh

Technical card

Resolution: 800x589

Data source: Backyard


I imaged the area of sky which Pluto is traversing in Sagittarius, almost 48 hours apart. I took 20 subs the first night and 40 the second, with 40 darks and 40 bias frames. The processed images were combined into this 2 frame GIF animation, where the movement of Pluto can be clearly seen. This is substantially the process used by Clyde Tombaugh in 1930 to discover the planet , now designated a dwarf planet. Travelling at 4.6 kms/ sec it travelled ~ 28.5 arc secs in that time and a distance of nearly 800,000 kms. Yet it is so far away that it will take 248 years to make one orbit of the Sun.
Just for the fun of it.
