@WastelandWandrr while not obvious, one can define a new location with its own coordinates in kStars.
The included EKOS platform provides scheduling, imaging, guiding and plate solving far beyond the capabilities of Stellarium.

Oh, neat. Using the very latest version of INDI I was able to successfully connect KStars/Ekos to my Seestar S30 Pro. Full control over the mount, camera, filterwheel and focuser, with a proper sequencer.
This should give me more control over calibration and (re)focussing, amongst other things. Going to take a while to learn how to use it, though.

Linux Flatpak 🤬
Warum zeigt mir ein flatpak-Programm beim Dateipfad wenn eine Datei oder ein Pfad ausgewählt wurde /run/user/1000/doc/.... anstatt /home/user/... (wo die Auswahl tatsächlich liegt) an?
Hat schlussendlich dazu geführt, dass keine einzige gespeicherte (oder eben nicht gespeicherte) Datei auffindbar ist - offenbar wurde ins Nirvana gespeichert.
Konkret hab ich die flatpak-Version von KStars verwendet, kein einziges aufgenommenes Astro-Bild ist irgendwie zu finden. In Summe 2,5 h Belichtungszeit. 🤬
Flatpak, ich dachte das ist auch dazu da um Dinge einfacher zu machen und auch um sich das compillieren vom Sourcecode zu ersparen?
Also doch wieder git clone... und stundenlanges compillieren. 😔Und wieder stundenlanges ärgern 🤬 und noch größere Zweifel an meiner Kompetenz. 😭

¿Sabías que existen herramientas específicas en los repositorios de Linux diseñadas para el cálculo preciso de eventos astronómicos, fundamentales para la práctica de la Wicca y el Paganismo?
Una de las más destacadas es KStars, un planetario para el escritorio KDE que permite no solo observar el cielo en tiempo real, sino calcular con exactitud los momentos de los equinoccios y solsticios, necesarios para planificar rituales específicos. Otra aplicación relevante es ccal, una utilidad de línea de comandos que genera calendarios lunares y solares detallados, permitiendo a los practicantes rastrear las fases de la Luna y las festividades de la Rueda del Año desde la terminal.
Para quienes llevan un registro de sus prácticas, hay aplicaciones de toma de notas disponibles en formato Flatpak y AppImage que son utilizadas para crear "Libros de las Sombras" digitales. Estas herramientas permiten organizar el conocimiento herbolario y ritualístico mediante etiquetas y enlaces internos.

Feeling brave, letting the telescope run overnight while I sleep. Fingers crossed #KStars looks after it all, and I'll be up at 7 to throw the cover over it!

#KStars debuts a new documentation site!
A comprehensive resource that helps you to get to know and make the most of KDE's fantastic night sky observatory and astrophotography utility.
At the moment, only English is available. More languages coming soon.

I'm not done with the processing of my Soul Nebula (IC 1848) data but I thought I'd share this little crop from the larger image which has strong "cosmic cliffs" vibes.

The Helix Nebula (NGC 7293) is a planetary nebula in the constellation Aquarius. At approximately 655 light-years from Earth, it is one of the closest of the bright planetary nebulae.
The planetary nebula is formed by the shedding of the outer layers of its central star near the end of its evolution. The energy from the central star causes the expelled gases to fluoresce.

Sh 2-155, from the Sharpless catalog, also known as the Cave Nebula, is a diffuse nebula in the constellation Cepheus, within a large nebula complex containing emission, reflection and dark nebulae. Sh 2-155 is an ionized H II region with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth.

The turnout was great though, we estimate about 120-150 people showed up, which is not bad for a small town of about 36k population.
We had a film on the history of astronomy on an inflatable screen and about a dozen telescopes, have visual, half astrophotography.
It was great to show our astrophotography images and equipment and answer a lot of good questions.
Despite the smoke, I was able to do a polar alignment using astrometry and capture some live images of the North America and Pelican nebulae which were almost at the zenith and were bright enough to "pierce" thru the smoke.

Here's a quick processing of the broadband RGB data on the Cocoon Nebula (IC 5146) in the constellation Cygnus. Narrow-band Ha data to be added later.

My flat panel setup: a sideways laptop with a simple, auto-refreshing, html page with uniform background color opened full-screen. I `ssh` into the laptop to adjust the background color to get the desired level for each color channel depending on the filter used.

SH 2-119 (from the Sharpless catalog of H II regions), also known as the Clamshell Nebula, is an emission nebula in the constellation Cygnus. It is fainter and not as frequently imaged as its western neighbour, the North America Nebula.
This image was captured over six nights between July 13 and August 1st. Two different dual narrow-band filters were used to capture the different wavelengths of the sulphur, hydrogen and oxygen emissions.

The Crescent Nebula (NGC6888) is a cosmic bubble about 25 light-years across, in the constellation Cygnus, blown by winds from its central massive Wolf-Rayet star (WR136).
This image was captured on July 26 & 28 under quite bad sky conditions; low transparency due to smoke from wild fires in the West combined with Moon illumination.

The Elephant Trunk Nebula (IC 1396) in the constellation Cepheus in SHO palette.
This image was captured over three nights with an OSC (RGB) camera and two different dual narrow-band filters (Sulphur + Oxygen and Hydrogen + Oxygen emissions) allowing the SHO palette (Sulphur=Red, Hydrogen=Green and Oxygen=Blue). SHO images are usually captured with a monochrome camera and three separate narrow-band filters, one for each emission line.

The Pelican Nebula (IC 5070) is an emission nebula associated with the North America Nebula in the constellation Cygnus. It is separated from the North America Nebula by a foreground molecular dust cloud.

The work on the Newtonian paid off and I'm happy with the results. This was the first time I tried the 150 mm f/5 Newtonian with the Starizona Nexus 0.75x coma corrector/reducer and my older ASI183MC Pro camera. The pixel scale (0.88"/px) with this setup is a good match with the scope's resolution limit and the faster focal ratio of f/3.7 with the reducer helps with the somewhat noisier camera.

A view of the extensive H II emission regions in the constellation Cygnus, just North of the star Sadr (γ Cygni), which forms the intersection of the asterism known as the Northern Cross.
At the bottom right is the NGC 6914 reflection nebula, blue halos created by the reflection of the light from blue giant stars on the surrounding interstellar dust.
The field of view is 3.2 x 2.1 degrees, with the celestial North to the left of the image.

Measuring focuser backlash on the Newtonian and dialing in backlash compensation in the Ekos software focus tab.
The objective is to find the largest displacements (number of steps of the stepper motor) that does not move the dial gauge needle when making alternated in and out focuser movements. Once the backlash compensation value is dialed in, the software will add this number of steps to the requested focuser movement when changing direction. This should help repeatability of the auto-focus routine that uses measurement of star size at different focuser positions to achieve the best focus.
