Another attempt this
            morning to see the comet before it vanishes into the perihelion
            solar glare in a few days. The issue of thin stratus clouds and
            fire smoke continue and prevent any deep shots of this comet.
            Today, I did get lots of shots of part of the comet as it traversed
            the clouds, but nothing to really stack. The top image here was
            taken just after it rose and was still in the cloud deck. The
            reds on the horizon are fire smoke. The second image is a bit
            better, after it cleared the clouds but then was too light out
            to get any tail length. This is only a 15 second exposure. At
            least with f/2, you have a chance at getting something in short
            exposures! We keep trying...
