I fired up the Xtreme + MFR-5, set the gain to 4 and took 3 images of M13 with exposures of 3,6,and 9 seconds. The results are interesting. The 3-second exposure shows a significant amount of color. The 9-second exposure shows little color. The core of the cluster is starting to "blow out," but more halo stars are visible.
As it does not get dark enough to align a scope until around 9:30 pm here, it was around 11:00 pm by the time I captured these images and I decided to pack up at that point as I had to work today. It's been about 6 months since the POD was delivered and it's good to have the observatory up and running at last!
