I had the opportunity to capture some images from a wonderful dark sky site in southern Indiana--the shores of Lake Patoka. The skies were amazing, with the Milky Way clearly visible. We were blessed with Mag 6 skies and good seeing. I took the VRC6, ZEQ25, DS16c, and a somewhat indifferent 2 inch focal reducer. As I had lots of people with me, I had to set up quickly and I didn't have time to fully adjust polar alignment or to ensure the best orthogonality of the imaging train--the idea was to just get some quick captures to keep everyone happy. I've posted some of the images to my album (briansxx), and they show just how well this setup works for fast imaging for public outreach. Integrations were between 20 and 30 seconds with x2 binning and gain close to max, with just 2 or 3 frames stacked in the MC software. I took one 30-second dark, which I used for all integrations (the only exception is the image of the Lagoon, which was a single capture with nio darks). I filtered out some of the noise, but the results are quite decent. With binning and a relatively fast scope (VRC6 at about f/4.5), the DS16c really delivers, with very little tweaking needed.
The trials, tribulations and small triumphs of a Charlotte, NC astronomer imaging under Bortle 8/9 skies.
