A couple viewers gave me some feedback after my first imaging session on M33, the Triangulum Galaxy. They said I should go for longer exposure times. So I did two more imaging sessions. One was with 120 sec exposures and the other with 180 sec exposures. Let me know what you think about how they turned out. Are they better than the 15 sec exposure session? Or do you think I just ended up with more noise? Enjoy the video and clear skies!
Here's some equipment I'm using for my setup:

This is a very well made barlow lens I've been using for visual astronomy. I found thought that this doesn't seem very compatible for astrophotography for my setup unless using the diagonal (only way to get camera focus).
