Since Hogwarts is my home, staying home for Christmas seems to be not so bad ...
I always liked this time of the year, the snowy silence full of expectations, the soft tinking of bells, occasionally interrupted by singing armours or suddenly swooping snowballs.
Although there is still much homework to do, I'm really looking forward to one of our pleasurable Christmas traditions and the best sport ever : Base-jumping in the restricted section!
But first we have to get our portkey to Stonehenge to celebrate the Solstice and the Christmas Star in the Great Conjunction 🌠 - oh, what a night!
🎄❄️⛄⚡🎄
Happy Solstice & Merry Christmas!

The Pieter Boele (1893) can be chartered for groups (max. 55 people) for round trips on the Merwede, around the island of Dordt, trips to Gorinchem, Kinderdijk or Rotterdam.
The home port of this beautiful ship is the historic Wolwevershaven in Dordrecht.
The wool weavers harbor was dug in 1609. This was decided to help solve the problem of the silting up of the New harbor due to flooding. The excavated sand was used to construct quays on both sides, one of which would later be given the same name as the harbor. In the early years, the port was still referred to as The New harbor, which is located south of the wool weavers harbor. The quay was initially named new storage
, named after the place where goods are unloaded and stored.. Eventually the harbor was named after the cloth makers or wool weavers who had settled on the quay. During a meeting in 1645 it was decided to also build houses on the quay. Initially there were fourteen. The image of the wool weavers harbor was determined by the a defensive wall. at the entrance of the harbour, where the Damiate Bridge was laid in 1639. This bridge connects two quays the wool weavers harbor and the Coopers harbor. In the 17th, but especially in the 18th century, the wool weavers harbor increasingly became a place where the elite settled. The area changed from a place of storage and industry into a stately residential area, so that living in a large house on the harbor gradually gave more and more status. At the beginning of the 20th century, it was still a place where the wealthy lived. More than one sixth of the inhabitants of Dordrecht belonged to the well-to-do bourgeoisie or elite. The Wolwevershaven was one of the most affluent streets in the city.
I did have help from Google and Youtube...........so here you have a 65mm Cube, Blood Sweat and Tears !
Mystery solved from yesterdays image. Holly, you will have to try harder!! I'm glad these turned out as well as I hoped as they made me chuckle while taking them. Plus I can't resist the deep colour in those ferns against the soft mist :) Taken in Hillock Wood, Buckinghamshire, or my second home!

The Raven:
Ravens are among the smartest of all birds, gaining a reputation for solving ever more complicated problems invented by ever more creative scientists.
The Raven is an acrobatic flier, often doing rolls and somersaults in the air. Young birds are fond of playing games with sticks, repeatedly dropping them, then diving to catch them in midair.
People around the world sense a certain kind of personality in ravens. Edgar Allan Poe clearly found them a little creepy. The captive ravens at the Tower of London are beloved and perhaps a little feared: legend has it that if they ever leave the tower, the British Empire will crumble.
Common Ravens can mimic the calls of other bird species. When raised in captivity, they can even imitate human words; one Common Raven raised from birth was taught to mimic the word “nevermore.”
The oldest known wild Common Raven was at least 22 years, 7 months old. It was banded and found again in Nova Scotia.

Solving puzzles is a hobby, addiction or compulsiveness? This is not as easy as it seems the maze pass is just barely big enough for the BB to fall through and really easy to come back out LOL. It is a close up, the puzzle is right at 3 inch across. I thought it was too big so quartered the puzzle to a 1-1/2 inch square frame to make it macro.
"You did the right thing, yeah
When you went and looked my way
I know, I know what you wanna say
You wrote it all on your face
(On, on, your)
Just beam me up, beam me up, leave me, don't bring me down
You've been fighting from the gallows
The shadows just come on out
(But you know)
It's all good when it's all bad
Be hurting all day but it's all math
You're losing your brain
And falling right back
It's all good when it's all bad
Been looking all day but it's all math
Just solve the equation
Get it all back." - QUIÑ ♫
The Horsehead and Flame Nebula, a stack of 11 shots processed in Photoshop. 1 of the frames was 10 minutes at ISO800, the rest were 20 minutes per frame, ISO400. Uncooled Nikon D810A on a Celestron CGEM2 mount, APT controlling the camera, ZWO guide camera with 60mm Sbvony scope for guiding with PHD2. The main scope is a Nikkor 600mm f/4 VR lens, shot wide open here. I had to keep adjusting the focus about every 40 minutes as the temp dropped, which is a pain! When I tried to do the meridian flip I messed it up and the scope lost its aligment, which for some reason I couldn't re-establish. I lost so much time I gave up for the night! Something I have to work on!
I think I’ve solved our winter energy crisis!
When the lights get turned off between 4 and 7 on those dark winter nights you just need to turn on a few fairy lights!
Problem solved!
I would suggest that there is a double benefit in that when they stop working, you could just sauté then in a little butter and that’s supper sorted too, however these bonnets are not toxic but have no nutritional value, a bit like a cream cracker in that respect.
So far I’ve collected about 150 and arranged them strategically around the house and guess what happened when I turned all the lights off…….…..yes, **** all!
The drawing board beckons, or was it the corkscrew?
NGC 2174, also known as Monkey Head Nebula, is an H II emission nebula found in the constellation of Orion and is associated with the open star cluster NGC 2175. It is thought to be located about 6,400 light-years away from Earth.

There were many questions with my last post of the red bellied woodpeckers but this solves the problem everyone had. Such a wonderful pair and delight to photograph !
Wishing everyone a memorable Memorial Day and a Day we give thanks to the men who fought and gave the ultimate sacrifice for our freedom . We think of their families and friends and pray for them today and always !! Thank you !

There were two of these gorgeous trees in full bloom at Lake St. Clair Metropark. The leaves looked like chestnut trees but the flowers were colored like buckeye tree flowers. Both of those trees have large palmate compound leaves. What were they, I wondered.
Later, I remembered seeing trees like these many years ago in Paris. They lined many of the streets and boulevards of Paris. There were the Horse-chestnuts with whitish flowers, and these pink/red flowers of the Red Horse-chestnut trees.
This picture is of Red Horse-chestnuts, a hybrid of Red Buckeye and Horse-chestnut...mystery solved (again).

NGC 1333 is a reflection nebula located in the constellation of Perseus. It belongs to the Perseus molecular cloud and is one of the closest star forming regions to us at around 1000 light years. One I must re-visit with one of my refractors as there is so much more detail to be found in this region. Found this one challenging to process. Imaged over 2 nights the 2nd and 26th of October 2019.

Rooks (Corvus frugilegus) are highly intelligent, gregarious members of the crow family (Corvidae) known for their complex social structures, unique appearance, and remarkable problem-solving abilities that rival those of great apes.
While not known for tool manufacturing in the wild, captive rooks have shown astonishing cognitive abilities in studies. They have been observed bending wire into hooks to reach food, a skill previously thought unique to New Caledonian crows.
Rooks have been observed engaging in "anting," where they rub ants into their feathers to use the formic acid as a pesticide. More drastically, a rook has been documented holding a smouldering cigarette butt under its wing to fumigate parasites.
A group of rooks is known by several collective nouns, including a "parliament," a "clamour," a "storytelling," or a "building".

Located between the Perseus and Sagittarius arms of our galaxy, is the Orion spur . This minor arm is home to our solar system, and named for its most prominent constellation, Orion. Although the sword asterism appears as a line of 3 stars, below Orion's belt, it actually contains a massive molecular cloud where new stars are being born. At approx. 30-40 light years in diameter, its far from being the largest in our galaxy; however, it's close proximity (1.3k ly) makes it the brightest in the northern hemisphere.
