Here’s a photo of Saturn, taken by Oscar Echeverri using a telescope, on his back porch in Ottawa. Oscar tells us:
I took the photo using my Canon Rebel T3 DSLR, mounted to my 8″ SkyWatcher Dobsonian telescope using the prime focus method — basically the camera is mounted to the scope with no lens so the telescope acts as a really long camera lens.
The image is really a composite of about 26 shots of Saturn stacked together. The individual shots were taken with at different shutter speeds. I took the shots between 12:54AM and 1:05AM on Thursday morning (May 17). Since my telescope doesn’t have automatic tracking, I had to re-aim it between shots to get the planet back in the centre of the field of view.
