I have been watching the well-known carbon star U cyg all this summer and fall as it has risen in magnitude. At the time of my observation it was glowing like a red hot ember at magnitude 9.0. This particular star ranges in visual magnitude from 12.1 to 5.9 over a period of 463 days. The red color deepens as it fades and becomes more yellow-orange as it brightens.
The star is located at RA 20 hrs. 20 min and Dec. + 47° 34’. The red orange color is quite striking visually.
Sketching:
For this sketch I used white sketching paper, a mechanical drawing pencil, assorted color pencils, several plastic erasers. The sketch was inverted and then scanned.
Telescope used: 10” f/5.7 Dobsonian with a 24 mm eyepiece for a magnification of 60x.

Frank,

Wow...WOW! What a beautiful sketch! U Cygni is on my list at #87, but after seeing this I'll probably bump it up. First I have 3 carbons in Orion to tag, then I'll have a look.

:grin:

Ps--More carbon star sketches, please!

Frank, did you order the code red!?!? Between you and Mark, I might have to see red, too.

Mark, Norme, Tom and Jef.

This is a nice red one like T Lyr when it is near minimum.

Thanks for the look.

Frank,
Nice work. I remember first starting out seeing a carbon star and wondering what I found, I called over an experienced club member and we plotted what I saw. I always enjoy seeing them since.

Thanks for sharing.

BTW, I love the blue-in-blue look of the star in the lower right FOV, which appears as if it's been consuming too much spice melange.

Very nicely done sketch and observation Frank. :jump:

I observed a carbon star once and was surprised how pronounced the color was.

Best

Eric
