Description

As a test of my ability to polar align, as well as part of a personal test to see the effects of light pollution, I attempted capturing M 13, the Hercules Cluster. An easy target visible to the naked eye through my telescope even under the Bortle 8/9 LA suburban skies. I managed 6 minutes and 20 seconds of integration, shooting 30 second subs at 200 ISO without any calibration frames.

The lack of calibration frames is immediately obvious, any attempt at trying to darken the background results in a very obvious vignette, and there is evident readout noise.

I plan to do the same under Amboy, though I will also attempt a more serious imaging session when there, using darks, bias and flats.
