Imagery from Keota, Colorado This is a piggyback chemical image using Kodak 400, in a Pentax MX SLR with a 50mm lens set at f3.5, for 20 minutes and guided on a Losmandy CG-14. I detented gamma about 20%, and increased brightness & contrast about 5%. Temperature about 35* taken at 11pm, no to slight breeze. Transparency7/10, seeing 8/10. A short span of high thin cirrus clouds for about 5 minutes, provided the haze filter to accentuate the brighter stars in this shot.
