Constellation shoot

I managed to adjust my EQ1 mount to the right latitude (51.5 N) and mounted my compact digital camera on it. I used the finderscope to take successive constellation pictures with 8 seconds exposure. The first target was Cassiopeia and the second one was Cygnus and Lyra. I took 12 frames of each.

The good news was that the technique produced clearer images than with the conventional camera tripod but I still managed to get star trailing. This meant I could get only a small field of view, so (for example) I could not show Lyra with Cygnus. Perhaps I needed more practice with aligning the image against a stellar background using the finderscope.
