Description

Finally collected enough data with the C11Edge to post an image. Seeing was poor for most of the shoot. It was pretty good for a couple hours on the fist night. Its frustrating when the FWHM of your subs go from 1.6 to 3.1., and no amount of refocusing can fix it. I wish I could have captured better data, but this is what the heavens saw fit to bequeath to me. In the end my stacks had FWHM of 2.4-2.8. Not terrible, but the first few subs I collected came in at 1.5, so naturally I was anticipating pin point stars. This is the culmination of my short sub, unguided tests, M99 is right at the meridian so I did not want to waste time flipping. M57 doesn't rise above 30 degrees for me until after midnight. M13 presented itself and I decided to go for it. The blue channel has about 1/2 the subs of the red and green and I had planned to capture more. But it will be cloudy for a week and then the Moon will interfere, so I am calling it quits. I had hoped for a deeper image, with more stars in the outer regions of the cluster, but I guess 20 sec subs can only accomplish so much from Bortle 6 in poor seeing. I might try to capture more and better data, but there are other targets that beckon to me. I am also considering installing the OAG so I can get back to longer subs and narrowband (Not looking forward to the struggle before me at all).

All in all, I like the technique. The only inconvenience is the need to correct for drift every half hour our so. It makes for a long night. Other than that - its pretty fun.
