M7 was fairly low on the horizon just above the sky glow from Austin to the south. Altitude was 28 degrees at the beginning of the sketch then lowered to 19 degrees by the end of the observation. The wide FOV of the 38mm Titan gave wonderful views nonetheless. The faintest stars were difficult to see and I detected them with averted vision. Once they were located, I could see them straight on.
Sketch created with AL template, #2 graphite pencil, super-fine Faber-Castell Pitt artist pen “S”, 0.5mm mechanical pencil.

Erika,
Very fine sketch of M-7. Did you debate with yourself about including the globular cluster NGC 6453 just off the edge of your sketch to the west?

Nice, Must have taken some time to lay down that many stars. Impressive.

Tremendous sketch.It's fun to also go after Cn 2-1, M 1-30, Hf 2-1 and NGC 6453. Your sketch reminds me I need to do one that includes both Messier 7 and NGC 6453 in the same field of view.

I did see NGC 6453 and kicked myself afterward for not moving M7 over just a bit at the beginning of the sketch so that I could include the glob in that sketch as well.
My first thought was, "I can white out the FOV circle and add the glob." Then I let out a sigh and decided I would include it next time.
thanks for the kind comments everyone.

Really nice and realistic sketch!
I personally think M7 should look a little bit brighter, but then stars would loose their "pinpoint" look.

Erika,
Nicely done--a very careful observation. The TFOV of that scope/ep combo must be a couple of degrees? M7 is also a great binocular object.
Another name for M7 is Ptolemy's Cluster. He reported seeing it visually in 140 AD and described it as a "nebula following the sting of Scorpius" (he might have combined M6 with M7 as all one nebula). http://messier.seds.org/m/m007.html

thanks everyone. And thanks for the feedback, Michael.
Phil, I didn't record both the start and finish time on this sketch. Those type of star fields normally take me about an hour and a half - longer if I use my Dob instead of a GEM.
