Another example of a gas cloud that is both ionized and at the same time dissolved by intense stellar winds. Here, it is the star Gamma Cassiopeia that shapes the nebula IC 63, also known as the 'Ghost of Cassiopeia'. Newton 300/1350, Panasonic S5 mod, 30 min Ha/OIII, ISO 800. 🔭 #astrophoto

The result of yesterday's cloudless night: The emission nebula NGC 6820 with star cluster NGC 6823. The hot, young stars of the cluster erode the surrounding gas and dust. Newtonian 300/1350, Panasonic S5 mod, 65x30s RGB + 130x30s Ha/OIII, ISO 800.

If you ever come to Vienna, I recommend a visit to the Kuffner #Observatory on the outskirts of the city. We had a special tour there last night from a dedicated club member. Central is the large refractor (270/3500) from 1887, the third largest in Austria. 🔭

My take of tonight's #lunar eclipse. The totality was hidden by clouds, unfortunately. 🤷‍♂️

Our #sun, which currently displays numerous spots and a particular large, complex group of sun spots. It's great that the peak of solar activity seems to persist for a while longer! Panasonic S5 mod, Skymax102/1300, 5% of 260 frames, 1/400 sec each, ISO 100 🔭 #astrophoto

Trifid Nebula (M20), imaged 2 nights ago before it hid behind the rooftops. The red part is an emission nebula, ie hydrogen ionized by the central star cluster - while the blue part is a reflection nebula Panasonic S5 mod, Skymax102/1300, 30 min, ISO 800, Siril/Starnet/Graxpert/Gimp 🔭 #astrophoto

I added some H alpha to my recent image of the nebulae Sh2-54, Eagle, Omega, and Messier 24. The HII emission regions stand out a lot clearer. Also, the colors are a bit more realistic now. 🔭 #astrophoto

The Milky Way between the open star clusters M11 (left) and M26 (bottom). Here, no dark clouds obstruct our view into deeper regions of our galaxy. Panasonic S5 mod, Redcat51/250, 80x30sec, ISO 800, dualband filter 🔭 #astrophoto

The Pacman nebula (NGC 281) - obviously trying to catch Schedar 😉, the brightest star in Cassiopeia. Pacman is an emission nebula almost 10,000 ly away. At its center it hosts prominent dust bands and an open star cluster. Panasonic S5, Redcat51, ISO 800, 80 min total 🔭 #astrophotography

Starless Version of the Heart and Soul Nebula in Cassiopeia. The Soul Nebula to the left is also called the Embryo Nebula, a name which suits its appearence better, I'd say. Panasonic S5, Redcat51, ISO 800, 70 min, 30 sec per frame. Stars removed with Starnet/SIRIL. 🔭 #astrophotography

Our nearest large neighbour, the Andromeda galaxy, accompanied by two small satellite galaxies, as seen from a shore in Brittany. Here, they fortunately switch off street lights at midnight 🙂👍 Redcat51, Panasonic S5, 75 min total, 30 sec per frame, ISO 800. 🔭 #astrophotography
