My 987/988/989 finally!!! 20080329

Telescope: Borg 45ED II
Camera: DMK 31AF03
Close up with Tele Vue 2x barlows

On the camera issue: I've swapped the PCI slot for the Firewire interface and the problem gone! I guess it solves a software issue on the hardware, since by swapping the PCI slot, Windows XP recognized this as a new hardware and so the drivers are re-installed.

Back to the solar imaging session, first batches are in H-alpha, taken with Coronado Solarmax 40 with BF10, close up with 2x barlows:-

Seeing was very bad at 3/10, transparency from 8/10 to sometimes 0/10 due to floating cloud, those cloud was pretty fast.
