The astrofest skies were unusually kind (fog free) this year after 1am, allowing many of us to feast on the photons M33 and M31 if so inclined. I captured M33 data over a few nights along with some Ha, planning to combine in some data from late last year from 10 Chain Hill. Most of this was shot between 20 and 30 degrees elevation, so its pleasing to see some colours starting to come out.
Final image is almost 12hrs total, HaLRGB: 4.2/2.4/1.5/1.5/2.0 hrs taken with the the FSQ106/QHY9/HEQ5.
Marc kindly agreed to share his M33 data, which I haven't included in this first pass (err, 10th pass) attempt. Comments and critique welcome. Sigh, I'm missing AF skies.....
