NGC 6960 and Environs
Date: June 30, 2008
Location: Seven Sisters Observatory - Manchester MI
Equipment: Megrez 90 APO, FFIII, Canon 10D Modified IDAS LPR Filter
Conditions: Excellent! Best night of the year so far
Film: None! DSLR @ ISO 800
Exposure: 3 X 600 seconds with 3 X 600 seconds dark frames
Comments: I took this shot as an experiment. Last year I was shooting 5 minute sub frames. Since I got the IDAS LPR filter I have been able to increase the sub-frame exposure. I tried a 10 minute sub frame to see if I could tease out some of the faint OIII and H-Alpha streaming down from Pickering's Triangular Wisp. Thin series of exposures shows a lot more than I have in my previous shots. The interesting news is the histogram was only at about 25% for each sub frame. I think I can increase the exposure to 15 or 20 minutes on this object. I will be revisiting the veil area all summer taking a good number of relatively long exposures - should be fun!
