Note to self - check images more closely before going to bed....
I was expecting to see the Pacman Nebula when processing and was very puzzled when looking at the data this morning - I swapped the coordinates in SGP with the Cave Nebula - oops...

Anyway the guiding was working well, new moon, clear night and some Perseids to keep me occupied for a bit. About 4.5 hours worth of SHO data. Processed as fairly simple SHO with a little channel mixing of the red and blue in Paint Shop Pro afterwards. The colour balance might not be to everyone's taste but I quite like it :-)
