Το τηλεσκόπιο Αρίσταρχος είναι ένα από τα πιο προηγμένα τεχνολογικά τηλεσκόπια της Ευρώπης, έχει διάμετρο 2,3 μέτρα και ζυγιζει 34 τονους ενω η αλταζυμουθιακη του στήριξη λειτουργεί με αντλία λαδιού.
ARISTARCHOS TRAVELS TO THE GALAXY
The Aristarchos Telescope is the largest and most advanced telescope in Southeastern EUROPE. It is part of Helmos Observatory based on the second highest peak of Mount Helmos Neraidorahi the site at an altitude of 2,340 meters near the ski resort of Kalavryta.
The name of ARISTARCHOS given in honor of the ancient Greek, astronomer and mathematician Aristarchus of Samios. The site is located from across Europe have the lowest light pollution and the telescope is above the clouds.
The Aristarchos Telescope is one of the most technologically advanced telescopes in Europe, and has a diameter of 2.3 meters and weighs 34 tons ,while the support works with oil pump.
This is an image of our natural satellite taken on a warm August morning last year.
Some prominent lunar maria (plural of mare, sea, lava filled plains) on the near side are (see annotated image for identifying these and other prominent features): Mare Imbrium (Sea of Showers, second larger lunar sea), Mare Serenitatis (Sea of Serenity), Mare Nubium (Sea of Clouds) and Oceanus Procellarum (Ocean of Storms, largest lunar basin). Prominent craters among others are Copernicus (diameter 93 Km), Plato (100 Km), Archimedes (83 Km), Aristarchus (40 Km, brightest lunar feature), Aristoteles (87 Km) and Tycho (86 Km, center of a large ray system).
Features close to the lunar terminator (day-night division) are seen better due to low angle illumination by the sun - that’s why the Full-Moon phase is the worse time to observes, as there are no shadows cast by lunar features.
Not the best image quality, since this is just one single exposure on a night with mediocre seeing (Moon altitude was also low, about 25o). Much better results are achieved by stacking lots of video frames on nights of good seeing conditions, still I was totally absorbed by simply observing through the eyepiece(s) with a bino-viewer, a very rewarding accessory for visual study of the Moon and the planets. I can also verify for those interested that the Sky-Watcher Mak 150 is a great scope for planetary observing and photography.
Thanks to everyone for looking. Clear skies to all!

This is a picture of the Full December Moon, at the time of Winter Solstice. The December Full Moon is called the Cold Moon or the Long Night Moon.
At the time of the Winter Solstice the Northern Hemisphere experiences the longest night of the year - at 40 degrees North the daylight is only 9 hours and 16 minutes.
The December Full Moon is opposite the Sun which rides low in the south during day, so the December Full Moon climbs high at night and lights the cold winter nights with its light.
Tycho crater with its long rays is visible at lower right, whereas the huge Lunar Maria Imbrium ("Sea of Rains") and Oceanus Procellarum ("Ocean of Storms") dominate the left part of the image (Lunar West).
Aristarchus crater is the brightest lunar feature of the vast Oceanus Procellarum, the largest of the lunar maria.
Next Month's Full Moon (January 21) will pass right through Earth's shadow, offering us a Total Lunar Eclipse. And since it will be near perigee, this will be a Super Full - Wolf - Blood Red - Moon!

The Aristarchus region of the 12.8 day old moon imaged on the 24th April at 20.21UT.
The brightest crater on the moon Aristarchus and is 40km in diameter. To its left is crater Herodatus (35km) with the sinuous Schröters Valley snaking off to the left above it.
To the right of Aristarchus is the almost obliterated, lava flooded, Prinz crater with the remains of some of its' walls still visible.
Bottom left of the frame is the crater Marius (41km diameter) and directly above it is the Marius Hills or Dome field looking like many little pimples. These are in fact Volcanic Domes and were formed from more viscous lavas than those that created the lunar Mares. These hills represent the highest concentration of volcanic features on the moon.

It will be overcast for the full moon on Tuesday 11/12/19… so a little early :-) ...testing the 600mm.
The bright crater at the bottom is Tycho. The bright spot to upper left is Aristarchus. The one on a line between those two is Kepler, and just to the right is Copernicus. The one that looks like a big hole toward the top left is Plato.
Notice the edges where the rugged craters really show the relief contrast!
The big circle area on the right side is Mare Crisium. ...using Google Moon to identify the features :-) Shot handheld.
.
Cloud cover obscured bright moon light until the wee hours this morning. Then it was really bright, shining into our bedroom.
We seniors know these things as we're often up in the night.
Not one to pass up a large, bright moon (okay, stop chuckling) I stepped out to catch it before it dropped below the neighbor's roof line.
Yes, this is a composite as there wasn't a way to get the house in focus and the moon in focus in the same shot.
One of the ways I know I'm getting older (not just how many times up in the night) is that I have to keep going back to the diagram which tells me the names of the moon's seas and craters.
I've got the seas Serenity, Tranquility and Fertility down pat. I remember consistently Copernicus and Tycho but the craters Stevinus and Aristarchus keep eluding long term memory.
But I keep working on it.
I can learn new things.
But then it pushes something old out.
My most recent moonscape featuring the prominent Copernicus, Aristarchus and Gassendi craters.
The image has been shot on January 18 from my backyard in Luxembourg. The seeing conditions were pretty good.
It's a crop out of a 6 pane mosaic. For each pane I stacked 20% of about 2.000 frames.
The saturation is increased by a fair amount in order to highlight the mineral composition of the moon's surface.

Moonscape featuring Copernicus, Aristarchus and Sinus Iridum. Image taken with Maksutov 180/2.700mm and ASI 178mc camera from my backyard in Luxembourg. Increased saturation to highlight the mineral composition of the moon's surface.
Taken from Coral Towers Observatory using a Skynyx 2-2 high speed camera and 16-cm Astrophysics Apochromatic Refractor at F/16 on a software bisque PME mount.
Taken a few days before the official date of the recent "blue supermoon" on an exceptionally clear night in Mannum by the Murray River. The area beyond Mannum is known for being one of the best dark sky sites in Australia, (Australia's first internationally recognised International Dark Sky Reserve) and on this cool crisp evening, it lived up to its promise even when viewing the bright moon rather than the stars. I always love catching the moon like this just a few days before being full, to show off the wonderful rugged details on the surface.
I have just highlighted a crater which looks slightly blue compared to all the others - top, right of centre of image. You need to pixel peep to see it. A quick Google search has others mentioning the same thing about this crater. Apparently it is a natural colour of a relatively young crater which appears blue compared to the surrounding more brownish soil. It is more apparent if I deliberately over saturate the original shot, but this image here is presented at "straight out of camera" levels of saturation.
(update - I believe the blue tinged crater is the Aristarchus crater and has been the subject of much discussion about the colour over many years)
I have since posted a second cropped shot with a little saturation applied to highlight the colour a little more.
This was a handheld shot. Gotta love modern image stabilising!
The 97% illuminated moon imaged during the evening of 10 May. Conditions were very still and the moon was bright and couldn't be ignored!
The waxing lunar terminator has nicely highlighted the iconic Pythagoras crater with its prominent central peak. It is visible on the waxing left limb around the half-way point of the image. For an idea of scale Pythagoras is around 130km in diameter.
Brightest crater on the moon, the bluish coloured crater Aristarchus, is very obvious towards the lower left.
Once again subtle differences in colour and tones on the lunar surface are evident. This being due to mineral variations in the lunar topography.
I used my Askar 71mm telescope and my ZWO 2600MC to capture this image.

The 30% histogram, which seemed to work well for recent closeups of Mons Rumker, Aristarchus Plateau, and Marius Hills, seems to have muted the colors and contrast in this image. In processing, it was much more difficult than usual, and the image quiality is not up to par with what I can usually produce.
i have collimated the scope and i can see a improvement in sharpness of the images . I have not adjusted the mirror much at all but it makes a big difference .
Another heavily cropped shot of the Arisarchus crater referred to in the previous moon photo. This one has had a little saturation applied to the whole image in post to highlight the amazing bright blue colour in this crater compared to the surrounding craters in the same area.
I am still researching more about this intriguing crater.
Lovely clear conditions were a surprise for the evening of Friday 15th March. The beautiful moon was hard to ignore so I captured this image.
The waxing moon was 36% illuminated when I imaged it and was in the constellation of Taurus.
The centrally peaked crater Theophilus near the moon's centre is particularly dramatically illuminated as it emerges from the lunar terminator into lunar dawn. Early light just catching the central peak and part of the crater's walls.
Also the walls of crater Proclus (with its associated rays), towards the top of the image and near the Mare Crisium, are catching the sun's light strongly.
Proclus is second in albedo only to crater Aristarchus.
Imaged with an Esprit 120ED and a ZWO 2600MC camera.
Thanks for looking!
This is a closer view of this fascinating lunar region, featuring the brightest lunar crater Aristarchus and crater Herodatus to its right. The lava "drowned" Prinz crater can be seen to the left of Aristarchus - some of the crater's walls are still visible.
The largest rille or valley on the moon, Schröter's Valley can be seen snaking below both the crater pair. The rille starts at a 6km crater north of Herodatus.
This part of the rille is often called the Cobra's Head due to the resemblence to a snake's head! The rille has a maximum diameter of 10km, reducing to 1km near its terminus.
Believed to be volcanic in origin Schröter's Valley has a fine rille within its floor - so we have a rille within a rille!
A portion of this has been resolved in the image within the Cobra's Head section.

After cloud cover all day a brief unexpected clearance last night allowed me to image the waxing moon.
The moon is approx. 85% illuminated and the brightest area of the moon, the crater Aristarchus, is nicely contrasted within the gloom of the lunar terminator. (LHS)
The subtle colour variations within the moon's surface are also nicely revealed.
My small short focal length refractor, a Skywatcher ED72, was already mounted and I attached it to a Nikon D5300 DSLR to capture this image.
The Sun is rising over the Aristarchus Plateau, which features a number of volcanic formations and a bright, prominent impact crater. It is also the site of many reported Transient Lunar Phenomena and Radon has been measured by the Lunar Prospector mission, leading some to conclude that it remains volcanically active.
The most striking volcanic feature is Vallis Schroteri, a long sinuous valley. It is the largest of its type on the lunar surface. Other minor rilles and volcanic domes can also be found on the plateau.
The plateau's brightest feature is Aristarchus, a 450 million year old lunar impact crater that is the among the brightest craters of its size. The crater's "freshly" exposed material is so bright because it has not yet been darkened by exposure to space weathering. At 3.5 km, the crater is deeper than the Grand Canyon.

Great nebula in Orion constellation. It is a multiple nebulas region. On the left side on the photo is Sh2-279, named “Running man nebula”. On the right is a massive Messier 42, brightest and closest star formation cloud to the Earth.
All the image data was captured during 4 separate nights from my backyard home observatory. As this region is rather too big for my telescope focal length and for my DSLR sensor size, i decided to built 2 panels mosaic to show both nebulas in more adequate frame size. Two stacks of images are joined in the middle (left and right) + very bright M42 core captured with shorter expositions so that details could be visible.

Aristarchus was quite independent. He produced his own electricity which allowed him to run two lightbulbs, three servers and a microwave. He really didn't need to be so conservative. His online marijuana business made him tons of money.

It is closest planetary nebula to Earth. It's characteristic eye shape and bright colours make it one of the most attractive objects on the sky. For me it happen to be a hard target to capture as it lays very low on my horizon.

With three seas and two craters labeled.
Some years back I'd noticed that my shots of the setting moon looked different from those of the rising moon.
That prompted me to try to learn the names of some of the moon's features to better understand what was happening.
From rising to setting, as the moon follows its path across the heavens, it twists in a clockwise direction. At this time of year it twists almost 120º.
Serenity, Tranquility and Fertility are the three easily discerned dark seas that are close to 12 o'clock on the rising moon.
By the time the moon sets, they are now at 4 o'clock.
Tycho is the huge bright crater seen at 4 o'clock on the rising moon and twists to the 7 o'clock position at moon set.
Aristarchus crater is a pretty cool feature. It's tiny but exceedingly bright so easily picked out most of the time. You can see how it moves from the 7 o'clock position to almost 12 o'clock between rising and setting.
The three seas and the two craters form a nice triangle which helps to keep me oriented when looking at the moon.
When you see a shot of the moon and things look wonky, it means the moon was probably shot when it was near the zenith of its arc across the sky.
The moon wobbles a bit as it moves around the Earth and we both move around the sun. There are times when more of the other side becomes visible at the perimeter.
Yesterday turned out to be a good day for shooting the moon.
In the morning I caught it setting in the early morning and then caught it rising in the evening. At this time of year it rises and sets pretty far north so I can see it rising to the north of the Sandia mountain far earlier than in the summer when I have to wait for it to clear the mountain.
Putting together the shots and the labels also was a good opportunity for me to relearn Photoshop's type tool and how to create a path for the lines and how to stroke a path to make the lines visible.
Since I made this black and white...
... Happy Donnerstagsmonochrom!
