NGC7331 and Stephan’s Quintet

Filed under: Observation Journal — Ed @ 3:30 am

Tonight, I spent quite a bit of time figuring out drift alignment using my DSI camera. I think I’m finally getting the idea of how to do this. Tonight, my alignment wound up so close that periodic error in the drives became the biggest source of instability and so I was able to take some long exposures that I stacked. While I’m pretty happy with the picture above, I plan on taking many more exposures to really bring out the detail in this area of the sky. NGC7331 and the other galaxies are found in the constellation Pegasus. NGC7331 is the galaxy in the upper right. Stephan’s Quintet is the group of 5 galaxies in the bottom left of the image. Four of the five galaxies are seriously interacting with each other and on a collision course. It’s a neat target that I’ve seen some great images of in the past and had wanted to visit for a long time.
