Always great to see and learn something new, thanks!

A red gas nebula to the top left, which is called the Wizard Nebula. The red-green structure at the bottom right is the Lion Nebula. Dark dust structures visible, too. Several bright stars. The one in the middle of the image is a variable star called Delta Cephei.

Wizard and Lion Nebula. North of the image's center is Delta Cephei, the prototype of the Cepheid variables. Its actually a quadruple star - here, two stars of the system can be seen.

Reddish gas clouds surrounding a central bright star. Close to this star a smal, traingular-shaped refelction nebula is visible.

The "Lower's Nebula". A relatively unknown emission nebula in Orion. The star at its center also illuminates a small, triangular reflection nebula.

Thanks for info, that podcast was new to me! 👍

The Skymax is not optimal for deep sky imaging (and we had a full moon, by the way), but GraXpert helps.

Did some re-colouring to approximate the Hubble palette...

Unfortunately, neither time nor sky 😏 Great image!!

The bright North America Nebula fills the right side of the image, together with its smaller companion, the Pelican Nebula. The Clamshell Nebula is found in the left part of the image.

Close-up of the Clamshell Nebula, showing inter alia dark dust globules in front of red emission gas structures.

Often overlooked is the Clamshell Nebula (SH2-119), a faint emission nebula located east (left) to the famous North America Nebula (NGC 7000).

A cluster of bright, blue stars in the center of the image illuminate surrounding gas and dust structures which in effect shine blue in the stars' vicinity. Further out, the dust is visible as grey-brown clouds against the background sky.

The Pleiades. Longer exposures bring out the faint dust structures through which this young star cluster is currently moving. Close to the bright stars, the gas and dust clouds strongly reflect the blue star light.

Red emission region to the top left image with dark dust structures in front of it looking like a horsehead. Bright Orion Nebula to lower right.

Horsehead Nebula and Orion Nebula - this overview of a region in constellation Orion shows how "close" these famous deep sky objects are when looking at our night sky. (Image taken with Redcat 51/250)

🔭 #astrophoto

Red emission nebula structures and dark dust lanes are crossing the image. To the left, a red-blue nebula is visible.

In addition, here is an oversight of the region around IC 1396. A very fine target (especially for longer focal lengths) is the Lion Nebula (Sh2-132) to the east of IC 1396 (left side of image).

🔭 #astrophoto

Almost round reddish nebula with numerous dark dust cloud structures inside. To the right of the nebula's center, a particular long dust cloud is visible that is being eroded away by the central hot star.

My favorite 2025 image: IC 1396 in Cepheus with the famous Elephant's Trunk Nebula to the right of its center, a stellar nursery, its very young stars being visible only in infrared.

A vast reddish nebula structure, littered with myriads of stars. At the bottom, a small crescent-shaped nebula.

The beautiful Milky Way around Sadr, the supergiant in the center of Cygnus.

Adjacent to Sadr is the Butterfly Nebula (IC 1318), an emission nebula with intense dark dust lanes in front of it.

At the bottom, the small Crescent Nebula (NGC 6888), which surrounds a Wolf-Rayet star.

Two red nebulae, the left one being shaped like the North American continent, the right one resembling a pelican.

In constellation Cygnus, the North America Nebula (left) and the Pelican Nebula (right) belong to the most prominent emission nebulae.

Mare Imbrum

Sinus Iridum with wrinkles visible close to the terminator, i.e. at the boundary between day and night on moon

My favourite region on the #moon, Mare Imbrum, with adjacent craters Sinus Iridum, Plato and Copernicus.

In this moon phase, special tectonic features, so-called wrinkles are visible on the floor of Mare Imbrum, inter alia Dorsum Heim and Dorsum Zirkel

In addition to the bright stars and known emission nebulae of constellation Orion, a large red circular loop is visible, spanning the whole constellation.

When imaging the constellation #Orion long enough, the faint "Barnard's Loop" becomes visible, an emission region measuring some 300 light years across.

A bright star at the top left and a reddish gas cloud below, the latter obviously being eroded away by the stars stellar wind.

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'.

In the center of the image is a cluster of bright stars surrounded by reddish gas clouds and dark dust clouds, both being shaped by the intense winds that are emitted by the stars.

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.

Karl Schwarzschild performed the first photographic astrometry on the smaller refractor mounted parallel.

The large refractor in the observatory's dome

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.
