It may look like a bird flapping when slowed down, but I can assure you if it is, it's a microbird.
I'm recording this through a 9.25" or 2380mm telescope using a gen 3 nv device and a Sony a7s camera. Iso was at about 800 and shutter speed at about 1/50.
the area being recorded is equivalent to the orion nebula. Examples of area are in the video. Please tell me below in the comments section what you think of it. :o)
