M103 vs. The Double Cluster

Got another Messier Object on my quest of imaging all 110 objects (Messier Objects with an ED) with my Orion ED80. In addition stopped by the Double Cluster for a peak. M103 is located very close to Ruchbah, one of the five bright stars in the constellation Cassiopeia.

As a side note, I recently purchased the QHY-5L-II-M autoguider/planetary camera for autoguiding. So far I love this autoguider, it focuses really well on objects and quickly calibrates using PHD, even when moving on to different objects. See my recent post on the Autoguider at http://kurt-zeppetello.blogspot.com/2015/11/new-images-for-messier-quest.html.
