Playing with Sirius, the Brightest Star in the Night Sky... (Rainbow Star!)
Actually while capturing this star, this idea came to my mind. I thought to capture in this way like light Light painting photographs (Here Star Light painting!). As I wanted to capture the colours of Sirius in one frame, I shaked my tripod to see the result in slow shutter speed... Now many colours can be seen in image... Though it looks weird in the end.
