 The comets twin tails have now nearly aligned. The dust component is the broad fan to the right of the coma, and the gas tail, now quite dilluted by dust is the ray shooting toward the lower right. It is a pale blue now. While no longer a naked eye object near mag 7, it can still be easily seen in my 9 x 60 binoculars. Here is a shot with the 10 inch for a total of 9 mins, with the camera set for a binning of 2 and consisting of three color frames combined.
