Description

Tried M51 Spiral Galaxy again from the backyard observatory. Only captured less than 1 hour of data because of clouds, again! This time stuck with CCD temp of 5C due to frosting issues. Also better calibrated my frames this time around. Also set dithering to "very high" in SGP. Dithering seems to help quite a bit. This is definitely easier to process than DSLR images, but still challenging due to light pollution. No LP filter used.
