Another stable night shows comet 13P/ Olbers inching higher into darker evening skies.  The wind torn tail structure hints at the solar dynamics that must be affecting this comet.  Couldn't get my other (widefield) backyard setup, setup.  Would have loved to see the edge of the FOV twist in larger extent.

Second night spying Olbers with a pair of 18 x50 image stabilizing binos.  Scanned the skies two nights ago finding a fairly large diffuse blob without a central condensation and a slight elongation upward-pointing from the horizon.  Seeing the comet wasn't easy, since it was less than 10 degrees up off the mountain ridgeline, there weren't any bright stars nearby as a guide and its brightness was spread over a moderate area.  HOWEVER, last night I waited until the comet was just above the horizon.  Olbers looked much brighter, easier to spot and quite a bit larger with an even larger extension upward.  Was the brightness and ease at spotting Olbers last night a true affect of the comet changing or better sky conditions?  This image may provide a hint to this question (IDK)
