Location:        Seven Sisters Observatory - Manchester MI   

Equipment:    Megrez 90 APO, FFIII, BB LPR Filter, Canon 10D Modified 

Conditions:     Fair - some hazy patches and high humidity

Film:               None!  DSLR @ ISO 800    

Exposure:       8 X 900 seconds with 2 X 900 seconds dark frames

Comments:     These longer sub frame times are helping but I have to find a way to compensate for the color shift induces by the LPR filter.
