Brocchi’s Cluster a Redux of 2014 Collected Data

I decided to pull out some data from way back in 2014, in this case, Brocchi’s Cluster. I wanted to apply some of what I learned over the years in processing techniques. This is only six minutes of data (6 x 60 seconds) using a Canon 6D, 400mm f/5.6 lens and my trusty iOptron ZEQ mount. This cluster is also known as the Coat Hanger asterism, as you can see why. You can also see the small open cluster to the right known as NGC 6802.

The top two stars are M and K class stars and have a noticeable orangish color to them.
