Jupiter, captured through a brief window of very good seeing before midnight of November 22, 2023. 12.5" f/5.1 home built newtonian (driven by OnStep), TeleVue 3x barlow, ZWO ASI290 mc, UV/IR blocking. I captured the video clips for creating this image using SharpCap Pro with a gain of 300 and an exposure of 8.2ms. I captured string of about 20 1-minute video clips, processed using Astrostakkert!3, using only 50% of the frames. I chose 11 consecutive 1-minute videos. I used an altazimuth mount, so I had to carefully correct for frame rotation before derotating in WinJupos. I processed the image(s) using Pipp, Registax, and Photoshop.
Fairly significant atmospheric turbulance last night so couldnt pull much detail out of Mars images.
Mars is starting to get smaller again - just 19 arcseconds here.

NGC 5189 is a planetary nebula located in the constellation Musca, about 1,780 light-years away from Earth. It is notable for its complex and striking structure, which resembles a barred spiral galaxy due to its distinct S-shaped pattern.
Some Key Features of NGC 5189:
Structure: Unlike typical planetary nebulae, which often appear as simple circular or elliptical shapes, NGC 5189 has a complex and irregular morphology. The nebula's most distinctive feature is its S-shaped appearance, formed by bright, twisted filaments of gas that stretch across its extent.
Formation: The nebula's unusual shape is likely a result of interactions between the fast winds from a dying star, the central stellar remnant (likely a white dwarf), and the previously ejected material. The intense radiation from the central star ionizes the expelled gases, causing them to glow and form intricate structures.
Central Star: The central star of NGC 5189 is a hot and dense remnant of a star that has exhausted its nuclear fuel and shed its outer layers. This stellar remnant emits intense ultraviolet radiation that ionizes the surrounding gas, contributing to the nebula's luminosity and vibrant colours.
Colors and Composition: The nebula's colours, ranging from blues and greens to reds, are due to different elements within the gas clouds being ionized. Oxygen often appears blue-green, hydrogen appears red, and nitrogen can create reddish hues, giving the nebula its distinct appearance.
Observations: NGC 5189 has been extensively studied using both ground-based telescopes and space observatories like the Hubble Space Telescope. The high-resolution images reveal its intricate, filamentary structures, providing insights into the late stages of stellar evolution and the dynamics of planetary nebulae.
Significance: NGC 5189 is an excellent example of how the end stages of stellar evolution can produce remarkably diverse and beautiful structures in space. It serves as a case study for understanding the physical processes that shape planetary nebulae and the fate of stars similar in mass to our Sun.
NGC 5189's unique shape and vivid colours make it one of the more visually striking planetary nebulae observed in our galaxy.
NGC 5189 has an angular size of 2.33 X 2.33 arc mins, presenting a little challenge with a 10-inch telescope. As an experiment, I tried drizzling the data and upscaling by 2 to see what the result would be. I captured Ha, luminance, red, green, and blue filtered light to create a coloured Ha-LRGB image.
I love the teal colours present in many Planetary Nebula. To my eye, the teal-coloured inner symmetric knots are stunning, the highlight of the image. The contrasting red S encasing the inner filaments is so cool. It looks like something from a sci-fi movie: an ancient structure containing a glowing cosmic beacon against a backdrop of stars.

It's FebRovery again, my favourite themed building month.
So let's begin with a modification of set 10497 (or as I like to call it, the "UCS Galaxy Explorer") into a rover.
As far as names go, "Planetary Explorer" was the obvious and only choice. The rear cargo compartment contains a small skimmer-type vehicle to mirror the rover carried by the original
The Medusa Nebula is a planetary nebula in the constellation of Gemini. It is also known as Abell 21 and Sharpless 2-274. It was originally discovered in 1955 by University of California, Los Angeles astronomer George O. Abell, who classified it as an old planetary nebula.
Full data
Nova Persei 1901, or GK Persei for short, is a nova in the constellation of Perseus that lies at a distance of roughly 1400 light years and spans roughly 1 lightyear in diameter.
A nova is an astronomical event characterised by a sudden spike in brightness of a white dwarf star in a binary system. This increase in brightness is triggered when the white dwarf, drawing material from its donor star, undergoes a thermonuclear explosion on its surface, unleashing a burst of energy and temporarily increasing its luminosity. This thermonuclear explosion takes place when the white dwarf accumulates enough material from its donor star so that the ever-increasing pressure and heat trigger an explosion. The so-called donor star can be a main sequence star or even a subgiant - for GK Persei the latter is the case. As details would go beyond the scope of this text, I recommend reading this for anyone interested.
As the name suggests, the nova was discovered in 1901 when it was pretty bright at magnitude 2.7. The nova attained a maximum brightness of mag. 0.2 (even brighter than Betelgeuse!) and then faded over the years, reaching a magnitude of roughly only 12 over the next 3 years. Nowadays the brightness sits at an average of mag 13-14. However this nova is not in a steady-state and undergoes frequent change in brightness - years after the discovery it was observed that the nova shows spikes in magnitude (in the order of 2-3 mag increase) that repeat regularly about every 3 years for a period of about 2 months which is due to outbursts in the system. More about those outbursts later in the text.
For the Deep Sky Collective (DSC) “GK Persei '' was an interesting target as it images only very rarely due to it being a pretty hard target as it’s faint and small. With the small FOV group of the DSC we started gathering data in November and imaged for a total of 3 months. As the weather this season hasn’t been very kind, not everyone was able to contribute, however with a total of 14 people working on GK Persei - 1 Editor, 2 stackers, 1 additional MSGR providers, myself coordinating it and only 9 photographers- we still managed to get a total of 265h of integration - the longest ever on GK Persei.

Special thanks to:
Justin, who stacked all of our files and ran a few tests to get the best result. Thanks for his efforts to the project and patience with stacking.
Carl, who gave the project members access to his NAS to upload their data and make the data transmission significantly easier. Also thanks to him for stacking Ha, as we had some problems with the initial stack and Justin wasn’t available.
Steeve, our editor who produced this wonderful and time-consuming edit you see here.
​​​Paul, Nicola, and Antoine and Dalia, who provided the team with MSGR references which is always a crucial step when it comes to collaborations.

...almost 50 planets have now been found inside this parallel planetary system, characterized by imperfect spherical celestial bodies.
Another Dimension - Font’s Point overlooking the Badlands of California's Anza Borrego desert. Spent sunset watching this spectacular view with friend and fellow photographer David Gregg. We then stayed on well into the night with several miles of dirt road back to civilization… but not before a good cigar while waiting for long exposure shutters to finish.
The comet was added in post just for dramatic effect.
Lik Observatory:
Lick Observatory was the world's first permanently occupied mountain-top observatory.
The observatory, in a Classical Revival style structure, was constructed between 1876 and 1887, from a bequest from James Lick. In 1887 Lick's body was buried under the future site of the telescope, with a brass tablet bearing the inscription, "Here lies the body of James Lick".
Before construction could begin, a road to the site had to be built. All of the construction materials had to be brought to the site by horse and mule-drawn wagons, which could not negotiate a steep grade. To keep the grade below 6.5%, the road had to take a very winding and sinuous path, which the modern-day road (SR 130) still follows. Tradition maintains that this road has exactly 365 turns.

A downward view of ESA’s rock-strewn recreation of the Red Planet, designed to put prototype planetary rovers through their paces.
Officially part of the Planetary Robotics Laboratory at the Agency’s ESTEC technical centre in Noordwijk, the Netherlands, the nickname of this test site is the ‘Mars Yard’.
An 9 x 9 m square filled with sand and different types of gravel and rocks, it is used to assess rover locomotion and navigation as well as the traction of wheels and other mechanisms – then check how these elements work together in practice, with tests observed using precision cameras and sensors.
The Planetary Robotics Lab is part of a suite of more than 35 ESA laboratories focused on all aspects of space engineering, available to wider European Member States companies as well as ESA projects.

I made a shot similar to this back around Christmas 2016. I wanted to try out a new lens - I sort of like this one much better than the previous! The warped bokeh really leads the eyes towards the light.🚀🌌

I know, this kinda falls short of the usual stuff I post and it may be of interest to nobody but I love the chaos in these images and how my imagination is triggered by it. For me this looks like a catastrophic event around the orbit of a planet, the barely lit center of the circle. The circles themselves could be planetary rings with the brighter one being ignited by the doomsday event.
On the other hand, this photo's imagined story stands in stark contrast of it's real scale. This being only a small cut-off wheel of 22mm in diameter, running at 20.000 rpm, making contact with a steel part.

The red (Ha Signal) is sh2-129, the flying bat nebula. The blue squid nebula (OIII signal) in this image (OU4) was discovered by the French Amateur Astrophotographer Nicolas Outters in 2011. It is very faint. I used a tone mapping process originally described by J-P Metsavainio to bring it out.
The brilliant starry sky, the red sand and the ice structures piercing the foreground of this image combine to give the impression of a desert far from the reach of human footprints. A landscape that could easily be mistaken for the polar regions of our distant neighbour Mars.
The jagged tooth-like formations are not on the Red Planet however, but on the sloping hills of the Atacama Desert.
The formations are called penitentes — structures made of snow and ice that form mostly at high altitudes. The low pressure, moisture and temperature at these altitudes help to create this interesting and rare behaviour in the freezing of ice. The strange structures also have a tendency to orient themselves towards the Sun, which is why they are all perfectly aligned like a carefully tended garden of ice.
As if this beautiful quirk of nature wasn’t enough, above the structures lies an even more magnificent sight.
The large blue star just above the hill is Sirius — the brightest star in the sky. Following the horizon to the left from Sirius, the ancient red supergiant Betelgeuse can be seen, located in the constellation of Orion. The second brightest object after Sirius is Canopus and it is seen here as a brilliant blue point at the right hand side of the frame.
This strange and alien-looking image was taken by ESO Photo Ambassador Babak A. Tafreshi.

BluShock Planetary Exploration is the new, official name given to BluShock Coalition's world designing and RP exploration operation, responsible for creating new, exotic and detailed worlds, for the BluShock franchise RP group.
Complex and incredibly detailed worlds at your fingertips.
Exclusive to BluShock.
Several new planet projects are currently in development, and we can't wait to share more in the coming months.
What started as a fun project with Vanargand, and Planet Idun, exploded into an ambitious project that gave us all this incredible idea. SL doesn't have enough exotic worlds and planets to explore, so we're changing this from here onwards.
Our next main world is Ingemar. An underwater planet, with crashed ships and wreckages above sea level, and deep underwater caves, with ancient aliens, as tall as skyscrapers, who once ruled the races of the galaxy.
