Almost like snowflakes, the stars of the globular cluster NGC 6441 sparkle peacefully in the night sky, about 13 000 light-years from the Milky Way’s galactic centre. Like snowflakes, the exact number of stars in such a cluster is difficult to discern. It is estimated that together the stars weigh 1.6 million times the mass of the Sun, making NGC 6441 one of the most massive and luminous globular clusters in the Milky Way.
NGC 6441 is host to four pulsars that each complete a single rotation in a few milliseconds. Also hidden within this cluster is JaFu 2, a planetary nebula. Despite its name, this has little to do with planets. A phase in the evolution of intermediate-mass stars, planetary nebulae last for only a few tens of thousands of years, the blink of an eye on astronomical timescales.
There are about 150 known globular clusters in the Milky Way. Globular clusters contain some of the first stars to be produced in a galaxy, but the details of their origins and evolution still elude astronomers.

Planetary alignment in the dawn of June 24, 2022. Mercury (as expected) is lost in the twilight (even if, with a lot of imagination and a little good will, one might see a tiny dot of light in the right place in the original RAW files), the rest of the planets are visible "in the correct order", i.e. corresponding to the actual distance from the Sun. The Moon (with visible Earthsine!) represents the Earth-Moon-system in this row: Mercury (Merkur) - Venus - Moon (Mond) - Mars - Jupiter - Saturn.

HiRISE (High Resolution Imaging Science Experiment)
HiRISE has photographed hundreds of targeted swaths of Mars' surface in unprecedented detail.
The HiRISE camera has provided the highest-resolution images yet from martian orbit.
The camera operates in visible wavelengths, the same as human eyes, but with a telescopic lens that produces images at resolutions never before seen in planetary exploration missions. These high-resolution images enable scientists to distinguish 1-meter-size (about 3-foot-size) objects on Mars and to study the morphology (surface structure) in a much more comprehensive manner than ever before.
HiRISE also makes observations at near-infrared wavelengths to obtain information on the mineral groups present. From an altitude that varies from 200 to 400 kilometers (about 125 to 250 miles) above Mars, HiRISE acquires surface images containing individual, basketball-size (30 to 60 centimeters, or 1 to 2 feet wide) pixel elements, allowing surface features 4 to 8 feet across to be resolved. These new, high-resolution images are providing unprecedented views of layered materials, gullies, channels, and other science targets, in addition to characterizing possible future landing sites.
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

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.

Thanks for looking
...almost 50 planets have now been found inside this parallel planetary system, characterized by imperfect spherical celestial bodies.
The DSN Resource Collection and Development Division or RCDD has a large team devoted to the scouting, collection, and processing of lumber. Here you can see one of the brave top cutters, a rare breed of thrill seekers who forge ahead of the ponderous industrial machines of mass tree cutting/planting which crawl their way through planetary forests to maintain a balance of old vs new growth in wide stripe like paths. The top cutters spend their time in the canopy layer performing scientific tests, mitigating issues the larger machines will encounter, and generally scouting things out. They’re joined by their trusty nuclear powered drone companions who function as friendly companions, but also communication relays, medical assistance, and fire suppression units when needed.
Rusty (the top cutter seen here) loves to sing a little ditty when traversing the boughs, and it goes a little like this (and don’t mind Rusty’s liberal use of copywrighted material as the base for his song, he just doesn’t know any better):
There’s a lady who’s sure
The sun on the leaves is gold
And she’s climbing her way to the tree tops
When she gets there she knows
If you listen real close
With a yell she’ll be heard cross the la-ands
Oh oh oh oh and she’s climbing her way to the tree tops
There’s a notch in the tree
But she’s not done yet no
‘Cause you know the old pines need two or three
In a tree by the brook
There’s a drone of hers yes
Watching over and waiting to save her
Ooh, this life is pure free
Ooh, this life is pure free
There’s a feeling I get
When I climb a big fir
And my spirit is bursting to see more
In my dark dreams I see
Rings of smoke through the trees
And I wake to a smile that it ain’t real
Ooh, this life is pure free
Ooh, this life is pure free
And it’s whispered that soon, if we call the top brass
Then the Duggo will lead us to reason
For he’ll send backup soon
For those who came first
And the forests will echo with chainsaws
If there’s a rough path ahead of you
Don’t be alarmed now
It’s just another challenge to beat
Yes, the lumber corps will see it through
And in the long run
There’s nothing we can’t tackle tomorrow
Yes this life is pure free
Your head is humming and it won’t go
It’s the buzzing oh
The saws are calling you to join them
Dear lady, can you hear the logs go
Tumble and roll
To the river they’ll make their wa-ay
And as we climb on up the tree
Our shadows hidden by the leaves
There wafts a pine scent we all know
That brings a sweet smi-ile to you
And you see the treetops in gold
And if you listen very hard
The wind will wind through the leaves oh
The lumber corps has come to climb
To reach the heights and not to fall

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.
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.

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.

Managed to capture an image of our nearest planetary neighbour Venus during the afternoon of the 26.03.20.
This is a false colour UV/IR filtered composite image in order to reveal some cloud definition in the thick atmosphere of the planet. Some brightening is evident at both poles.
The IR filter is mapped to red, the UV filter to blue and the green channel is a blend of both.
Imaged with a Celestron C8 and a ZWO 290MM camera.
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.🚀🌌

Why do some Hubble images possess unusual staircase-like shapes?
This Hubble image combines infrared, ultraviolet and visible light gathered by the Wide Field and Planetary Camera 2 on the NASA/ESA Hubble Space Telescope. This camera was operational between 1994 and 2010, producing images with an unusual staircase-like shape as seen here. This is because the camera was made up of four light detectors with overlapping fields of view, one of which gave a higher magnification than the other three. When the four images are combined together in one picture, the high-magnification image needs to be reduced in size in order for the image to align properly. This produces an image with a layout that looks like steps.
This image reveals Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies that is over 1,200 strong.
Messier 90 is remarkable; it is one of the few galaxies seen to be traveling toward the Milky Way, not away from it. The galaxy’s light reveals this incoming motion in a phenomenon known as blueshift. In simple terms, the galaxy is compressing the wavelength of its light as it moves towards us, like a slinky being squashed when you push on one end. This increases the frequency of the light and shifts it towards the blue end of the spectrum. As our universe is expanding, almost all of the galaxies we see in the universe are moving away from us, and we therefore see their light more towards the red end of the spectrum, known as redshift. Messier 90, however, appears to be a rare exception.
Astronomers think that this blueshift is likely caused by the cluster’s colossal mass accelerating its members to high velocities on bizarre and peculiar orbits, sending them whirling around on odd paths that take them both towards and away from us over time. While the cluster itself is moving away from us, some of its constituent galaxies, such as Messier 90, are moving faster than the cluster as a whole, making it so that, from Earth, we see the galaxy heading towards us. However, some are also moving in the opposite direction within the cluster, and thus seem to be streaking away from us at very high velocity.

This is a photo accurate representation of how I've seen the conjunction through a Skywatch 14" f4.6 Dobsonian, using the 17mm Ethos eyepiece combined with the 2X Powermate during the observation of the great conjunction of Jupiter and Saturn, and how well both of the planets fit into the eyepiece field of view.
My location was totally overcast for the last week and this evening I had a small window of opportunity to actually have a glimpse of the rare event, which no doubt, I will not have a another chance of experiencing.
This happened about 17 hours after the actual closest point between the planets, and most likely the difference would be so small that it wouldn't be noticeable without direct comparison.
This image was composited by first taking a series of shots through the eyepiece using an iPhone, choosing the best frame of the series than superimposing the overexposed planets with images of the planets captured separately with enough transparency as to accurately show how the planet details looked in the eyepiece.
Observation time was 22 December 2020 @ 09:51 UTC.
