Long Exposure Lagoon
Date: September 1st and 2nd 2007
Location: Seven Sisters Observatory - Manchester MI
Equipment: Megrez 90 APO w/ WO FF-III, Canon 10D Modified
Conditions: Good until Moonrise
Film: None! DSLR @ ISO 400
Exposure: 32 X 300 seconds with 8 X 300 seconds dark frames
Comments: I wanted to see if a longer total exposure at a lower ISO (gain) would help to minimize noise when shooting on these warm summer nights. I took these shots over two nights prior to moonrise and for the most part I am happy with it. I like the "stuff" that showed up in the upper left, IC 1275, IC 1275, IC 4685 and NGC 6559. Also visible near there is a planetary nebula - PLN 6-2.1 and the globular cluster visible near the bottom of the frame NGC 6544.
