Description

Using a second widefield scope (RASA 11 + asi 6200mcP) concurrently with the C14 HyperStar (image here https://astrob.in/pwzmkl/B/) I captured the same field and stacked the same time.  Little did I realize the asi 6200mcp was suffering from tilt in the lower right hand frame ( I could see this from the previous night's imaging where the elongated stars  rotated when I adjusted the rotation of the camera).  Never the less the starfield is rich in dust and stars.  Various revisions will show various aspect of the comet.  I've kept the full size of the images as I hesitated to resample and lose some cometary detail.
