h_chi-rgb.jpg

Embergeralm, Austria

h and chi Persei with their many stars could be seen in this patch of sky in northern Perseus, taken with an SBIG STL11000 and a Canon 400mm/f5.6 stopped down to 7.1. RGB filters were used from Astronomik. Exposure times were 3x5 mins with each filter. Additive exposure time is therefore 45 mins. During the red exposures some clouds drifted through the filed and reduce contrast. I hope I could get better data in the near future.
