Notes:

Very windy. Temperature at 2 in the morning is 19.5℃ !! The remains of Hurricane Helene has arrived. This session was to observe Comet 38P/Stephan-Oterma but I can’t find it, so switching to a few Messiers.

Exceptionally I have rotated the drawing so that N is up, to help comparisons with historic records of this famous object. I can see only one star within the nebula itself, on the SW edge. To each side of this star are circular bays. Opposite, on the E and NE edge there are suggestions of striations or rays, a bit like the outflow on the S edge of M82. No filaments within the nebula were seen. I have seen filaments previously using an OIII filter but the wind is making observing difficult today.
