As the Milky Way rises in the summer night sky, there is a multitude of objects to photograph. My last star cloud image, M24, inspired me to do more. LDN 772 is a dark nebula, sometimes called the Loch Ness Monster, in the constellation Vulpecula. The data were collected in one short night after I tested a new PC mounted on my rig and generated a PEC curve using PEMPro. There are two small blue reflection nebulae, LBN 133 and 134, that are illuminated by young, hot stars.
