Description

This was my first multi-night imaging project. Shot over the course of 4 consecutive nights from Sept. 3-6, 2016. I shot one set of flat, dark flat and bias frames but shot darks each night to more closely match the sensor temps due to the DSLR being uncooled. Here in VT this object stays fairly low in the southern sky and the heat/moisture from Lake Champlain on the cool late summer evening can really do a number on local seeing conditions. Even though Clear Sky Chart indicated above average on all nights, there were times when seeing was probably barely average.
