Gamma Cygni Nebula

The Sadr Region around the central star Sadr (γ Cygni) in the Cygnus constellation contains the large H II nebula, Gamma Cygni Nebula (IC 1318). This nebula is partly obscured by dust, creating the Butterfly Nebula (IC 1318B) in the lower left of the image, just below Sadr.

Many other objects can be seen, including multiple star clusters and, most notably, the Crescent Nebula (NGC 6888) to the right of the center of the image.

This image was created with 2,984 × 2 s (1 h 39 min 28 s) integration time. Post-processing was done with #Siril, #GraXpert, #StarNet++, and #GIMP.

This time I documented the whole process in my #blog. If you have a camera, this is for you (no guarantees, though; I just fail along until it works for me): https://blog.picturavis.com/astrophotography-without-equipment/

Yesterday we visited the #Volkssternwarte #Köln ✨🔭 The weather was overcast, so conditions were limited, but we were still able to observe #Jupiter and its four #GalileanMoons #Io, #Europa, #Ganymede, and #Callisto.

The main #telescope is a 600 mm #Cassegrain reflector with a focal length of 5,400 mm, which enables high-magnification observations of #planets, the #Moon, double #stars, and bright planetary #nebulae.

Happy Space Science Saturday! The Cat's Eye Nebula, also known as NGC 6543, was one of the first, and one of the most complex, planetary nebulae ever discovered! It is estimated to be 1,000 years old. Planetary nebulae are named for their round shape, which made them appear to look like planets when viewed through early telescopes, but they are actually expanding gas thrown off by stars in their final stages of evolution.
