This was my first attempt to image this target and also my first attempt at composing LRGB images. Taken from the backyard in June 2015, from Diamantina, Minas Gerais, Brazil. Unfortunately I struggled with guiding due to a loose conection between the guide scope and the main telescope dovetail. I think PhD did a great job at guiding in this unfortunate condition.
