Description
Comet C/2021 P4 will be coming closer to us and the sun over the next two months.  It is not expected to brighten more than a magnitude or two, however we are talking about comets.  Currently a northern/evening and circumpolar comet, however the image circumstances were fairly tough.  I couldn't image the comet higher than 25 degrees with encounters with numerous coniferous trees and Mountain ridges interfering with the exposures.  Coloration indicates a dusty envelope.
