Comet Garradd

As a follow up to the previous post on white light observing with the 4 inch f/11 achromat, I observed and sketched Comet C/2009 P1 Garradd tonight.  There was a bit of dust and smoke in the atmosphere all day and I think that the transparency was impacted tonight.  Contrast in the scope is excellent, and I do believe that I was seeing a broad and faint tail extending in an easterly direction from the nucleus.

Sketch was completed at 0325 UT under average skies, using a 10mm Pentax XW (110X).  The comet has an estimated magnitude of 8.1
