*** Deconvolution
* Created star_mask_large - large scale structure 2, small scale 1, noise threshold 0.1, scale 8
* Created range mask - extracted luma, applied standard STF, then histogram shadow = 0.25 mids = 0.3 high = 1

*TGV - small noise
Created TGV masks - extracted luminosity, standard stretch (luminance_mask), curved it with black point at ~0.2 and white at ~0.5, moved histogram point to middle (tgv_mask)
apply tgv mask inverted to the image, give luma mask as local support

**Initial
* created a new multiscale linear transform, kept 4 layers using linear interpolation
* diffed from original image to create a "blurred" version of original image

* pixelmath sum the 3, rescaled, back to original image
**Second
* new multiscale linear transform, keep 5 layers
* diff from original
* extract luminance from blurred image, to use as a mask
* masked blurred image with its own luminance, gave it s-shaped RGB curve, big boost in saturation

The Temple was a monumental structure; it measured 120 m in length and 50 m across. The sixty massive columns surrounding the cella were well over 2 m in diameter and more than 21 m high. The Temple was topped with the largest Corinthian capitals ever sculpted, one of which, 2.5 metres in height, 1.9 metres in diameter and 20 tons in weight, was unearthed in 2013.
In AD 124, the city of Cyzicus was granted the role of neokoros, temple warden of the imperial cult. The people of Cyzicus declared Hadrian the 13th Olympian god.
The Byzantine chronicler John Malalas called the Temple of Hadrian at Cyzicus “a very large temple, one of the wonders" with a very large bust of Hadrian on the roof and a marble stele inscribed "of Divine Hadrian". (Malalas, Chronography Bks 1-7, 10-18)
Cassius Dio called it “the largest and most beautiful of all temples, writing that “its columns were four cubits in thickness and fifty cubits in height" writing that "in general, the details were more to be wondered at than praised.” (epit. 70.4.1–2).
Segona nit seguint a Venus en el seu passeig per les Plèiades. Li vaig posar uns fils davant del telescopi per crear la forma d'estrella.

Widefield (200mm) view of the Mars-Pleiades conjunction in March 2021. Not the closest approach (weather opportunities) and not a lot of exposure time in a light-polluted area but captured the distinct colour contrast of the two.
The theatre was built by taking advantage of the natural slope of the land and using local limestone blocks in the Hellenistic period. In addition to the seating of the theater, the orchestra and stage buildings were also unearthed.
M45, The Pleiades in natural color, with luminance and RGB combined. For the color I used 10 minute and shorter 5 minute exposures together with the luminance to help prevent the very hot blue stars from becoming bloated.
Total Exposure time 4.75 hours

Among the closest star clusters is M45, colloquially known as the "Seven Sisters". Due to its close proximity (a mere 440 light-years), and population of extremely hot and luminous stars, it can be easily seen with the naked eye near the constellation of Taurus. The number of visible stars in this open cluster can quickly tell an astronomer how dark a location is on a night of observation. Up to fourteen of the more than one thousand stars in M45 can be seen with the unaided eye.
The bright blue clouds surrounding the stars forms a reflection nebula known as the Maia Nebula. The enormous cloud of dust reflects the light from the hot young stars and was once assumed to be the remnants of the young stars' births, but is now known to be the serendipitous interaction of an unrelated dusty region being illuminated by the open cluster of stars passing through its interstellar neighborhood. Look closely and you will see the faint brown clouds of dusty material surrounding the cluster.
For comparison here is my earlier shoot from 2 years ago using a Canon 5D II DSLR together with the TMB 130SS
Noosa National Park, South East Queensland. This timelapse was taken on the morning of Sunday 2nd July, and it captures the Pleiades star cluster (also known as the "Seven Sisters"), Hyades star cluster, and Orion (behind the tree at the right) plus the crescent Moon all rising before the dawn light swamps the scene. The presence of a nice ketch in the bay added to the overall view!
The Pleiades
First (possibly failed) attempt at The Seven Sisters.
I could not resist their looks and gave them a go. Tried a few things, but ended up with just three salvageable shots. Here, the result of stacking those 3. Again, the usual stuff of an ordinary DSLR with an ordinary telezoom lens was used. Taken at a dark sky place, which did the trick to get an acceptable result.

Las Pléyades
Primer intento (posiblemente fallido) de tomar Las Siete Hermanas.
No pude resistir sus encantos y me decidí. Intenté algunas cosas pero terminé con solo 3 tomas rescatables. Aquí ven el resultado de apilar esas 3. Como siempre, usé solo una cámara digital normal y un lente teleobjetivo corriente.
Tomado en una zona de cielo oscuro, lo que ayudó a que pudiera obtener un resultado aceptable.
I took this picture of the Pleiades star cluster on Friday night from my backyard.
I used a Canon EOS Ra camera attached to a 132mm refractor telescope (WO FLT 132) to capture 3 hours of total exposure time.
You can watch me do it in the latest video: youtu.be/G2oke5_YYfk

The Pleiades, also known as the Seven Sisters and Messier 45, are an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth, it is the nearest Messier object to Earth, and is the cluster most obvious to the naked eye in the night sky.
The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.

The Pleiades (M45), sometimes referred to as The Seven Sisters. Shown here is the blue reflection nebula which surrounds the stars along with integrated flux nebula. This is a combination of 30 x 3 minute exposures taken with my Canon 6D and Canon 70-200mm f/4L IS Lens.

Skull Rock and Pleiades
A soon to rise near full moon was on the horizon and Pleiades was about to set when this was taken. Skull Rock is lighted by headlights from a passing car and a smartphone (blue).
Perhaps one of the most iconic and recognizable objects in the night sky, M45 (The Pleiades or Seven Sisters) is a beautiful open cluster of stars that graces our northern hemisphere skies every winter. Ancient legends, myths and traditions surround the Pleiades from almost every culture from the Greeks to Native Americans. Galileo Galilei is widely attributed to have been the first human to view the cluster through a telescope. M45 is considered an open cluster and is actually made up of around 800-1,000 stars and is located approximately 410-450 light years from Earth.
The brightest stars in the cluster dominate the view from Earth due to the cloud of nebulous dust that the stars are actually gradually passing through as they slowly move towards Orion's feet. Light from these young, bright stars reflects a largely blue and white spectrum of light off of the surrounding dust producing the fine illuminated filaments we can see today.
This photo was captured from our front yard in Richmond, VA with no light pollution reduction / filtering and consists of about an hour and a half of total integration time. Second photo is setup, and 3rd photo is courtesy of Stellarium and shows M45's location in the Northern Hemisphere sky at night for tonight.

The house had rooms arranged around a peristyle that rested partly on cisterns. An above-ground hunting mosaic, from which the house derives its name, has been left in situ, depicting the owner and his servants on a hunt.
Underground is a five-column hall with a swirling geometric floor.
The ray is the reflection of cloud due to crescent moon light. The starry sky in the evening becomes spring. However, the ground is a little waiting for spring.

The Pleiades class Corvette is built off the Atlas battle carrier platform. These small warships can be deployed individually or in trios as part of larger battle groups typically spotted with its parent Atlas BatltleCarriers. The Pleiades Corvette is also specifically designed as a long range hunter warship to chase down enemy vessels.

Greek Mythology:
Pleiades - Daughter of Atlas, and companions of Artemis Goddess of the hunt.

After building Atlas, it felt lonely that it was by itself, so for Bricking Bavaria I added 3 Escort Ships to protect Atlas, and subsequently important individuals.
