Bubble Nebula - NGC 7635
Date: September 15, 2007
Location: Seven Sisters Observatory - Manchester MI
Equipment: Megrez 90 APO, Canon 10D Modified
Film: None! DSLR @ ISO 1600
Exposure: 20 X 300 seconds with 6 X 300 seconds dark frames
Comments: I wanted to see the results using ISO 1600. The image is pretty noisy but I did capture a lot of signal in each sub-frame. My processing skills are not good enough to rid myself of all the noise yet. Note the open cluster M52 below the nebula.
