The first image is L300Bin1 RGB@180Bin2. This is using star alignment as the comet didn't move much over the timeframe.
The second image is a sigma-clipped average stack of 6 x 300 seconds luminance binned 2x2. The tail structure is seen more clearly in the second image.
I still haven't been able to see it naked eye (SQM reading 21.5 on that night). I think it's hidden in the light pollution of Kingaroy 10km to the southeast.
I have not been able to see it naked eye myself either. I have good sky where it is at present, but my vision over the last few years has become progressively short sighted due to a refractive error, probably from staring at computer monitors for too long! I need glasses.
Kevin, I first noticed my vision going when I was reading photocopied papers. I'd shrink down 2 page journal articles to fit a single A4 page and some of the subscripts on the equations were getting blurry. That was about 15 years ago. I got the presbyopia a bit earlier than most, in my 30's. Seems that around age 45 it's almost universal to lose near focus (unless you're long sighted to begin with).
I find glasses a pain when working with the scope, but it's not such an issue since I don't do much visual.
that's beautiful tail work!
