Nebula NGC6751 on 23/08/2016 at Thézac (dept. 17, France) Guiding: off-axis guider on C8 telescope at F=2000mm, LodeStar StarLight Xpress Telescope: C8 at F=2000mm Mount: SkyWatcher EQ6 Imager: Atik 314L+ at -7.5°C Moon: 74% visible Conditions: 21°C, dry air Exposures: L:2x120s bin1 R:1x120s bin2 G:1x120s bin2 B:1x120s bin2 Ha:1x120s bin1 Offsets: 15x0.001s in bin1 and 15x0.001s in bin2 Darks: 11x120s in bin1, 11x120s in bin2 flats: L:15x0.057s R:15x0.83s G:15x0.049s B:15x0.028s Processing: IRIS then GIMP. Commentary: good guiding thanks to the off-axis guider. I couldn't use the focal reducer as I couldn't reach the focal point, I need a shorter T ring. Need more exposure time.
