Carbon Star U Cyg
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.

Carbon Star RX Cygni

Hi!
I decided to submit a sketch of an extraordinary object: RX Cygni. It’s one of these very red shining carbon stars; nice to observe and unlike other deep-sky-aims, because you easily see colors, even in small telescopes. I suppose the most famous carbon star is R Leporis, which can be found in winter – much more intense than RX Cygni!
Information can be seen in the picture.
