A light snow fall in June in the Canadian Rockies made a pretty scene along the open water, trees and calm lakes. I wanted to wait for the sun to make a full appearance, but the sun was too immersed in the clouds that day - just means I have to go back (which I look forward to!).
The Orion Nebula is a massive cloud of gas and dust around 1,300 light years from Earth and is located in the constellation of Orion.
The Nebula is actually part of a much larger nebula known as the Orion Molecular Cloud Complex.
The first recorded observation of the Orion Nebula doesn't appear until 1610, and this was thanks to the telescope which had been invented two years earlier.
Using his telescope the French astronomer Peiresc noticed the diffuse nebula and noted down his observations, he is therefore credited with its discovery.
Throughout the 17th century many others independently discovered the Orion Nebula including the famous Dutch astronomer Christiaan Huygens. In 1774 the French astronomer Charles Messier included the Orion Nebula in his now famous catalogue of deep space objects, naming it Messier 42 or M42, a tag is still widely used today by professional and amateur astronomers.

IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a Galactic supernova remnant (SNR) in the constellation Gemini. On the plan of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.
IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

I captured these three combined shots against the sunset sky, watching it as the blue changed to purple to pink.
I used the skeletal shape of a Winter tree in my neighbours garden as the interest.

On an island of soaking stone
Water rises and makes it's home
Leaping up to the sky
Watch the drops as they fly
On the wind, through the air
Falling down, on stone now bare
Dancing wetly before all eyes
Placing kisses sent from the skies
Quite a boon for me, Kelvin Helmholtz and lenticular clouds both visible together on the same evening!
An extremely rare phenomenon, where a cloud produces a billowing wave pattern. They occur when there is a strong vertical shear between two air streams, causing winds to blow faster at the upper level than at the lower levels.
Height of base: Can be any height, but usually at higher levels.
Shape: A repeating breaking wave pattern.
Latin: These clouds are named after Hermann von Helmholtz and William Thomson, Lord Kelvin, physicists who studied turbulent airflow. There is no Latin etymology.
Precipitation: None.
What are Kelvin-Helmholtz clouds?
Resembling evenly spaced rolling ocean waves, Kelvin-Helmholtz are one of the most striking and rare cloud types.
How do Kelvin-Helmholtz clouds form?
They occur when two different layers of air in our atmosphere are moving at different speeds (a phenomenon known as shear). When the upper layer of air is moving at a higher speed than the lower-level air, it may scoop the top of an existing cloud layer into these wave-like rolling shapes.
Kelvin Helmholtz instability is a scientific phenomenon not exclusively associated with clouds. It can occur wherever there is a velocity difference across the interface between two fluids. The most obvious example is wind blowing over water, in which fast-moving air can create the waves on the slower-moving water.
What weather is associated with Kelvin-Helmholtz clouds?
The clouds are more likely to occur on windy days. They are often good indicators of aircraft turbulence.

The nebula Messier 78 is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.
M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th magnitude. These two stars, HD 38563A and HD 38563B, are responsible for making the cloud of dust in M78 visible by reflecting their light.

The Rosette Nebula (also known as Caldwell 49) is a large spherical H II region (circular in appearance) located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having formed from the nebula's matter.
The cluster and nebula lie at a distance of some 5,000 light-years from Earth and measure roughly 130 light years in diameter.
The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022.[1] The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen.[6][5]
The comet's systematic designation starts with C to indicate that it is not a periodic comet, and "2022 E3" means that it was the third comet to be discovered in the first half of March 2022.[5]
The comet nucleus was estimated to be about a kilometre in size, rotating every 8.7 hours.[7][8] Its tails of dust and gas extended for millions of kilometres and, during January 2022, a third anti-tail was visible.[9]
The comet reached its perihelion on 12 January 2023, at a distance of 1.11 AU (166 million km; 103 million mi), and the closest approach to Earth was on 1 February 2023, at a distance of 0.28 AU (42 million km; 26 million mi). The comet reached magnitude 5 and is visible with the naked eye under moonless dark skies.[10][11][12][13] (Wikipedia)

This particular day I was sky watching...and omg these dark exiting clouds with light to the north....this is how it appeared to the south. How wonderful!!...I'd been waiting for this moment for years.
After procrastinating for several years I decided to buy a GSO 8” F4 Newtonian with the heavy duty focuser. Apparently it’s a rebranded TS-Optics Newtonian. It has a larger secondary mirror than the F5 version that will suit my full frame DSLR. With my C11 I could only squeeze in the smaller galaxies and planetary nebulae. As an example, on this frame, I would have only fitted in Barnard 33 or The Horsehead nebulae with the focal reducer on. Here’s my first image through my new scope with the pesky bright star Alnitak creating some havoc. The new scope arrived just before the Vicsouth Star Party so unfortunately I didn’t have time to practice collimating it at home first. I’ve now done a full circle with scopes because I owned an 8” Newtonian from Astro Optical suppliers some 50 years ago.

Coastal brown bear in Alaska fishing for his meal as the tide comes in. The skies were not the best when we first landed on the beach but cleared up later in the afternoon. A chartered sea plane took us to this remote area to watch the bears - it was an amazing experience.
The Horsehead Nebula (also known as Barnard 33) is a dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex.
The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of its resemblance to a horse's head.
The Flame Nebula, designated as NGC 2024 and SH2-277 is an emission nebula in the constellation of Orion.
The bright star Alnitak, the easternmost star in the Belt of Orion, shines energetic ultraviolet light into the Flame and this knocks electron away from the great clouds of hydrogen gas that reside there.
The Running Man Nebula Sh2-279 is an HII region and bright nebulae that includes a reflection nebula located in the constellation Orion. It is the northernmost part of the asterism known as Orion's Sword, lying north of the Orion Nebula. The reflection nebula embedded in Sh2-279 is popularly known as the Running Man Nebula.

The graceful, winding arms of the majestic spiral galaxy M51 appear like a grand spiral staircase sweeping through space. They are actually long lanes of stars and gas laced with dust. Such striking arms are a hallmark of so-called grand-design spiral galaxies.
In M51, also know as the Whirlpool galaxy, these arms serve an important purpose: they are star-formation factories, compressing hydrogen gas and creating clusters of new stars.
Discovered by Charles Messier in 1773, M51 is located 31 million light-years from Earth in the constellation Canes Venatici.

I walked up to the ridge just before dawn. I hunkered down on in the road ditch to stay out of their radar and enjoyed watching them graze in the corn stubble.
February started very snowy and cold. A reminder that winter is not over yet. Was a pretty scene in the blue hour of the morning with the frost and this Great Gray Owl on the hunt for breakfast. Taken in Alberta, Canada.
“I lingered round them, under that benign sky; watched the moths fluttering among the heath and hare-bells; listened to the soft wind breathing through the grass; and wondered how anyone could ever imagine unquiet slumbers for the sleepers in that quiet earth.”

This is has been cropped by only 5% due to stacking artefacts.
The only frames I had to discard were those affected by satellite interference.

The Sculptor Galaxy is an intermediate spiral galaxy in the constellation Sculptor. The Sculptor Galaxy is a starburst galaxy, which means that it is currently undergoing a period of intense star formation. QHY 183mc pro cam on a sky watcher Quattro 250P scope , 30 x 60 sec exposures.
In one of my night photography workshops, me and two clients observed something truly beautiful, milky way (even though not quite obvious), light polluted clouds and aurora borealis. I once again sat there to enjoy the scene, good night, lake Minnewanka.
Didn’t intend to be this close to the owl. Pulled over on the side of the road to review the photos I had (scrolling on the back of the viewfinder). I had been watching a deer so had my window down. Big great gray owl lands directly beside my vehicle on a farmer’s post. I had to get one shot - and move slow enough but fast enough (sometimes they take off fast and this fella seemed to be as surprised as I was that we were within close proximity). Clickety-click and he flew away.

The Andromeda galaxy is 2.5 million light years from Earth and is approximately 30% larger than our own Milky Way. It is heading our way and is expected reach us in about 4 billion years. You can also make out a companion galaxy, Messier 110. Similarly, our own Milky Way has two satellite galaxies: the Magellanic Clouds. This image was captured over two nights as Andromeda reaches a maximum elevation of only 10 degrees above the horizon and that makes capturing an image more time- limited.
