We have had cloudy, wet weather here in the Midwest during June. I finally got two clear nights. These shots were taken about 15 minutes north of my house near Rockford, IL. Ihe location is the best that I have found near my home...only one farm light about 400 yards away. The light domes this close to Chicago, etc. are severe, but I was just able to make out all four stars that make up the bowl of the little dipper. Of course, the comet was well down on the northern horizon, and with pre-dawn twilight coming swiftly, I wasn't able to get the focus quite right either, Oh well.
Nikon D700, ISO 6400 for 5 sec with 120-400mm Sigma Zoom at 400mm. I located the Comet with 15x70 Canon Stabilized Binoculars and then found it with the lens at 120mm on a motorized dutch mount, with the camera above on a Manfrotto 410 head and tripod. The green glow really helped, but wasn't apparent with the binoculars.
Shelly says my SV90TF will be ready to ship soon. If I get it in the next few days, I know of a Conservation Area near La Belle, MO that has the darkest skies I have sofar found in the Midwest. I will try again there. No traffic, farm lights, houses, or light domes, and all trees are at least 100 yards away.
