Title

-Comet: 220P McNaught -Date/Time Local: 9/20/26 0:01 AM MST -Date/Time UT: 8/25/26 7:01 UT -FOV: 125' x 100' -Orientation: N up -Seeing: 6 -Transparency: 8 -Orig. Scale: 1.6 arcsec/Pixel -Instrument: 10" f/2.9 Newt -Exposure: 2h total LRGB -Camera: Atik 16200 -Location: Payson,AZ Notes: Very low surface brightness indeed, only a very small part of the tail was seen in the 5 min subs. Extensive IFN all over this field makes for challenging processing. Used blurred stars only image to subtract out residuals in comet only image left over from StarXterminator.
