Out of all my bright, single star images, I think this one is my favourite. Sirius – the brightest star in the sky. Two-frame (vertical) mosaic with camera in landscape mode. 3 x Sky90 refractors and 3 x M26C (non-Trius) OSC CCD cameras. Each frame is 90-minutes of 2-minute subs (so that’s actually 270-minutes of actual exposure time per frame).
