The ever-challenging Astronomy hobby has led me to experimenting with taking images through a telescope.
My telescope is a rather large reflector on a mount that moves in altitude and azimuth (Dobsonian). These telescopes are not generally suitable for astro-photography because they do not compensate Earth rotation. However having 22″ of aperture allows to image brighter deep-space objects with reasonable results using exposure time under 15 seconds.
Saturday night was half-clear and I put my Sony NEX-5 camera into the telescope and took a few images (it always helps to take a few images and stack them together to minimise noise). It was quite thrilling to take an image of the Orion Nebula and see a lot of colour on the camera screen so I kept going and tried a few more objects. The images below are quite modest in modern astro-photography but I’ve had a lot of fun doing it.
