SXV-H9 CCD camera, Revelation 66mm doublet refractor @ F3.5 using an altair astro 0.6 reducer, Skywatcher HEQ5 pro mount. Photoshop CS5, Registar, CCDStack2.

120 x 30 second unguided exposures of M31 taken on 16th August 2015 from my new home in Prudhoe. Colour added from a previous DSLR image taken in November 2014 from Newcastle Upon Tyne. This image was a bit of an experiment, I’d recently moved house and hadn’t had chance to properly polar aligned my mount so I went as wide field as I could with the small chip on the ccd camera and used short exposures to avoid star trailing. I chose to image Andromeda as it was big and bright and I had a chance of getting a good image with enough short exposures. It turned out a lot better than I expected and is showing a lot more contrast and detail in the dust lanes than the mediocre DSLR image I’d taken from my old house in the city.
