During sunset, a cloud flew in in an amazing shape (a bird, a dragon, and maybe an angel ...)
A little understanding of the physics of cloud formation underscores the complexity of the atmosphere and sheds light on why predicting weather for more than a few days is such a challenge.
Six types of clouds you can see and how they can help you understand the weather.
1) Cumulus clouds - On a sunny day, rays warm the earth, which heats the air located directly above it. The heated air rises upward due to convection and forms cumulus clouds. These “good weather” clouds are like cotton wool. If you look at the sky filled with cumulus clouds, you can see that they have a flat bottom, located at the same level for all clouds. At this altitude, air rising from ground level cools down to the dew point. It usually doesn't rain from cumulus clouds, which means the weather will be good.
2) Cumulonimbus clouds.
Small cumulus clouds do not rain, but if they grow and grow in height, it is a sign that heavy rain is coming soon. This often happens in summer when morning cumulus clouds turn into cumulonimbus during the day. Cumulonimbus clouds often have a flat top. Air convection occurs inside such a cloud, and it gradually cools until it reaches the temperature of the surrounding atmosphere. At this moment, it loses its buoyancy and can no longer rise higher. Instead, it spreads out to the sides, forming the characteristic anvil shape.
3) Cirrus clouds form in very high layers of the atmosphere. They are smoky because they are composed entirely of ice crystals falling in the atmosphere. When cirrus clouds are carried by winds moving at different speeds, they take on a characteristic curved shape. And only at very high altitudes or at high latitudes, cirrus clouds give out rain that reaches the ground.
4) Stratus Clouds - A low-lying, continuous cloud sheet that covers the sky. Stratus clouds are formed by slowly rising air or gentle winds that cover the cold land or sea surface with moist air. Stratus clouds are thin, therefore, despite the gloomy picture, it is unlikely to rain from them, a little drizzle at most. Stratus clouds are identical to fog, so if you've ever walked in a mountainous area on a foggy day, you've been inside a cloud.
5) Lenticular clouds. Smooth and lenticular lenticular clouds form when air is blown up and over a mountain range, and as it travels over a mountain, the air descends to its previous level. At this time, it heats up and the cloud evaporates. But it can slip further, as a result of which the air rises again and forms another lenticular cloud. This can result in a chain of clouds extending far beyond the mountain range. The interaction of wind with mountains and other surface features is one of the many details that must be taken into account in computer simulations to obtain accurate weather predictions.
6) Kelvin - Helmholtz like a breaking ocean wave. When air masses at different heights move horizontally at different speeds, their state becomes unstable. The boundary between the air masses begins to ripple and form large waves, such clouds are quite rare.

Trying my hand at some landscape shots! 😊
You know I scream in my dreams like an animal
I know it feels like it's wrong to be something else
We know those thoughts live with us
sunk down, them nerves much thinner
I crawl, you sob
No sanctuary found
When daylight finally falls
Until the morning comes
My eyes can't see
But I can feel
What is it?

The F‑22 Raptor doesn’t just defy gravity it bullies it. Caught in a post‑stall, nose‑high attitude, the jet hangs in the sky like it owns the lease, sliding backward through a burning curtain of anti‑rocket flares. Magnesium fire blooms behind the airframe in a cascading wall of heat and smoke, each flare carving a streak of molten light across the sky. To the crowd, it looks like the Raptor has lost the fight with aerodynamics. To the pilot, this is just another Tuesday a deliberate, controlled maneuver that only a fifth‑generation monster with thrust‑vectoring arrogance could pull off.
The airframe shimmers in the flare glow, edges lit like a blade, the jet drifting backward in a way that should make physics file a complaint. This is the moment where the Raptor stops being an airplane and becomes a statement: “I can fall any direction I want.”

Uhmm, ouch, Mistress?
What's up? Are you still complaining?
This new toy - it's got twice as much spikes as the old.
Isn't that nice of me? That's only half of the pain for you.
How's that?
Didn't pay attention in physics? p=F/A (*), so if we double the area, the number of spikes that is, we halve the pressure.
But these spikes are sharper than the others!
Hmm, you've got a point there.
One-hundred and fifty, Mistress. In my back.

(*) pressure is force per area. And funnily enough, the abbreviations that were so difficult to learn in german, just seem logical when you're writing in english.

It was so interesting to watch the frost form around the water droplets on the window. It was a toasty 20 degrees inside my garage, but much colder on the other side of the glass. Forecast calls for temperatures to drop to -10 degrees F (-23 C) by morning, with windchills beyond -20 F.

All that Jazz (Chicago)
Come on babe, why don’t we paint the town?
And all that jazz
I’m gonna rouge my knees and roll my stockings down
And all that jazz
Start the car, I know a whoopee spot
Where the gin is cold, but the piano’s hot
It’s just a noisy hall where there’s a nightly brawl
And all... that... jazz
Skidoo
And all that jazz
Hotcha...Whoopee
And all that jazz
Slick your hair, and wear your buckle shoes
And all that jazz
I hear that Father Dipp is gonna blow the blues
And all that jazz
Hold on hun, we’re gonna bunny hug
I bought some aspirin, down at United Drug
In case you shake apart, and want a brand new start
To do... that... jazz
Find a flask, we’re playing fast and loose
And all that jazz
Right up here is where I store the juice
And all that jazz
Come on babe, we’re gonna brush the sky
I betcha lucky Lindy
Never flew so high
Cause in the stratosphere
How could he lend an ear
To all... that... jazz?
Oh, you’re gonna see your sheba shimmy shake
And all that jazz
Oh, she’s gonna shimmy till her garters break
And all that jazz
Show her where to park her girdle
Oh, her mother’s blood’ll curdle *
Did she hear, her baby's queer*
For all... that... jazz!
No, I’m no one’s wife
But, oh I love my life
And all... that... jazz!!
That jazz!

I've been very curious how just a half of my old doubleanastigmat would render wideopen on 8x10. And even more, de-focussed on purpose.
It's a High Five

I can't tell
I just did

I asked for the hand*

I could tell a bit
but all those would be afterwards reasoning and explanations for myself
I do see them
and remember
but for the image
it's in the world
and that's what it is about in the first place
and it would be afterwards reasoning really
looking back I wonder
cause all I connect with it now
has not happened yet, back then
It's nice to work like that
especially with all that size

Click on the image to Zoom In & Out on the Bubble Nebula. The "Bubble" is tagged in the image.
A widefield LRGB and SHO (SII+Ha+OIII) Narrowband image of the Bubble and Lobster Claw Nebula. The Bubble Nebula is also know as NGC 7635, Sharpless 162, or Caldwell 11 (a H II region emission nebula) in the constellation Cassiopeia. It lies close to the open star cluster Messier 52.
Also take a look at a closer view of the Bubble Nebula.
The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.
The Lobster Claw Nebula (Sharpless 157), is a bright emission nebula, and is clearly visible at the bottom right.

All art is but imitation of nature.-- Seneca (Letters from a Stoic - Letter LXV: On the First Cause)
The universe itself is God and the universal outpouring of its soul. --Chrysippus (Quoted by Cicero in De Natura Deorum)
Season of mists and mellow fruitfulness
Close bosom-friend of the maturing sun
Conspiring with him how to load and bless
With fruit the vines that round the thatch-eves run;
To bend with apples the moss'd cottage-trees,
And fill all fruit with ripeness to the core;
To swell the gourd, and plump the hazel shells
With a sweet kernel; to set budding more,
And still more, later flowers for the bees,
Until they think warm days will never cease,
For Summer has o'er-brimm'd their clammy cells. --To Autumn. by John Keats
