I was very fortunate, last Friday to have a clear sky where I live. and not only that. But a dry night, with little dew.I thought I would say farewell to the great globular Messier 13. I used my new Celestron C9.25 @ F6.3 with my Canon 1000D. I didn’t use any calibration frames. M13 was captured using a lower Iso setting at 200. I think this is better because it gives you a cleaner image. The image was shot, using 180 second sub exposures. The total time is 1hour and 06 minutes.NGC6207 is visible towards the lower left. Here is the result.
