Description

This was taken using the same PEC training performed the night before on Altair. In the meantime the equipment was taken apart and put back together for this session. The new target was in a different part of the sky and the mount was not tracking as well as the night before, so I reduced the exposures to 90 seconds for this shot of M103. As before, I just did a polar scope alignment. The image is a full resolution crop of the upper right corner.
