A slightly better night than the past few nights shows comet 13P/ Olbers in better form. The skies in my wester direction have been hampered by the uneven cooling along the mountain ridges as this comet is less than 10 degrees up from a true 0 degree horizon during mid capture. Twilight is also problematic, but hey this is comet imaging, we go for what we can get.

I've included the comet aligned, stars removed, stacked 29 x 45 second image for interest.
