5 pictures (156s + 136s + 141s + 140s + 197s) stacked, aligned and processed with Photoshop. Unfortunately the galaxy M110 is not on the picture, and M31 is off center to the left.

Doughton Park Prime focus f/4
800mm 16x Motor drive and manual guiding
Canon Digital Rebel 400 ISO 44 minutes 47 seconds
14 pictures (13x185s + 282s) stacked, aligned and processed with Photoshop. Unfortunately the galaxy M110 is not on the picture but starts to appear on the bottom of the picture. The air was very cold, below freezing, so there is no noise on the pictures. The problem is that there was gusts of wind, the telescope was shaking and the stars are not dots.
