LS80T first light (23-12-2010)

This is the first light of LS80T. The sun is not active today. Nothing special can be seen… The focal length of LS80T is 560mm, the DMK cannot image the full disc in one go. Luckily the width of the DMK sensor is able to cover full disc, the other shorter direction is being captured by drifting. One can see there is a slight horizontal artifact in the image. I don’t know how to get rid of it. Anyway suggestion???
