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.

M76 -Little Dumbbell

Object Type: Planetary Nebula

Location: Tarragona – Spain

M76 is a planetary nebula really awesome observed from a dark skies and with a good telescope aperture. Two distinct sections, one brilliant and compact, the other more extensive and diffuse. A very attractive nebula to be seen on a dark night and away from any light pollution.

California Nebula

NGC 1499 (California Nebula)

Hi! Asod, few days ago I saw the nebula California, was very curious to know if I could capture something visual light as they claim is faint. With my little scope locate ξ (xi) menkib, but looking even more side vision was getting nowhere, I knew I needed to filter, but had to try. By putting the filter magically appears, still not something brilliant, but do not strain your eyes because it is obvious that this is no, there is a dark area that crosses na nebula, but with side vision greatly improves contrast. The truth that I could not resist doing a sketch but as always with a very dim light, if you can not have problems adjusting to the darkness.
You only need a dark sky, wide field and nebular filter.

Regards.
