There is a brownish sphere east of center using the WWT on M37. There also seems to be some bubbling to the left of that object. Lensatic anomalies? Looks like a dust cloud. Something sticking out of the right side looks like a cloud. Then again, maybe gravity is capturing it, such as gravitational attraction to the larger mass. Or maybe it is a part of the cloud that is being pushed out by something. The brownish sphere looks fairly dense, and blocks the light behind it.
