  Strange thing in the center right hand side. Description: Black "orb" that seems to move randomly. Is it an asteroid? #ineedhelp

  That is a typical CCD/telescope optics artifact moving in the exact same motion pattern as other artifacts on other images.The motion is due to telescope dithering between the individual frames - the telescopes pointing moves slightly from exposure to exposure in a prescribed to make artifact appear to move erratically which makes them easily distinguishable from real objects.
