|Notes: *||Have to move on from this interesting object, as online images show
a pronounced blue color (not a great target with a red filter), which
more time will not improve much. During the time the full moon was too
near NGC 2371 to image, I turned to other parts of the sky to image
320 and NGC 1156.
First night was windy (with poor seeing), and the next was calm, but with more moon (60% ~ 61 degrees away), third night had lots of light cirrus. Only the fourth night was reasonably good (seeing, transparency), but had a 90% illuminated moon rising about 63 degrees underneath the object. Used the 'best' 80 out of 106 subs.
