Project Notes:
 

    98% moonlight? Beat it with shorter exposures. 
    Loss of fainter IFN and comet details of course. 
    I did once again block the direct moonlight by hiding the moon behind my cabin. 
    Globular cluster Messier M30 is closer to the Comet's orbital trail.. 
    Orbital Dust Trail fainter due to moonlight yet still be visible. 
    Brownish-yellow dust tail difficult to see however appears to be a large diffuse smudge along and below the right side orbital trail (best seen in the inverted color starless image https://app.astrobin.com/i/fhaed3?r=E). 
    Brightness measurement is mag 9.1 under heavy moonlight.
