My first Comet ISON sketch
      #6155989 - 10/24/13 05:29 PM Attachment (48 downloads)

Comet ISON’s magnitude was in the magnitude 10-11 range at the time of my October 6 Sunday morning sketch, tho’ all the sources I use show different magnitudes.

So for my observation, I thought it would be more interesting to show the magnitude of many of the the nearby stars I could see in my eyepiece. I used my 12.5-inch f/6.75 reflector and a 19mm Nagler Panoptic eyepiece for a magnification of 96x. Conditions were spectacular, very steady seeing at 5:00 am, and away from the the Zodiacal Light and Milky Way the limiting magnitude had been an impressive 6.5. I was able to see three 14.0 magnitude stars, two very near the comet. I tried higher and lower magnification (over 200x and under 50x) and couldn’t see the comet in any eyepiece over 125x.

Jane,

Very nice sketch. It remains to be seen if this early morning interloper lives up to all the hype.

I'll be observing it again visually (and sketching) Sunday morning, hopefully! Jane
