Deep Sky Tour at ESAC 2007-06-22

Last Friday, Leo, Michel, Fernando and me met here to try to image Venus with the UV filter and The Leo's telescope. After some trials and errors, the results were unsuccessful... it seems that we have lost some training using the Dobsonian with a Barlow... Later than the Moonset, we tried to image some deep sky objects from ESAC. Despite the light pollution, the bad seeing and a non-accurate tracking, some good deep sky images were taken. We used a C8 telescope with a 0.33 focal reducer and the DSI Meade CCD camera. The exposures ranged from 45 sec. to 1.5 minutes. Of course, we tried with some of the easiest Messier objects.
