    Default Butterfly Cluster (M6) and Ptolemy Cluster (M7)



    I imaged M6 and M7 on 7 August, the first really clear night that we have had the past few weeks.

    I love these types of images. I look up at the sky and don't see much because of light pollution and magnitude. I look through my telescope and see much much more. However when I turn my camera to the sky with a simple 30sec exposure, it always amazes me to see how many are really out there.

    Good job with these clusters.
