The Sun in H-alpha and Ha2cb

This morning a couple of hours clear sky. But still very poor seeing and a lot of wind. As a consequence my PC fell from the table, luckely without further damage.

I was able to connect my synscan to my PC and sharpcap. This made it possible to move the gear using the buttons in sharpcap. Much easier then working with the synscan handcontroller. Unfortunately due to weak USB connections, i lost connection everytime there is a gust of wind.

Beside this I'm not satisfied about the sharpness of the lines; in this case the H-alpha line. Even though I try to sharpen, using the collimator screw, focusser as cameraposition. Hopefully I can blame this later on the bad seeing. Let's wait and see.
