Date: May 4, 2008
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.
