When Galileo offered his opposers the chance to look into the telescope, many of them refused. They thought that that instrument was a trick of the Devil, a deceit to our perception to drift man away from the way of Truth - away from God. This so-called argument had been used so many times - e.g. when the opposers of the theory of evolution claimed that the Devil put bones and skulls of stranger antediluvian beasts into the rocks to deceive man - to demonstrate the mighty powers of unreason. I really cannot grasp how people can maintain such stances today but, well, this happens all the day, so this could be a limitation of my own little mind. However nobody can deny that that rough telescope - together with Van Leeuwenhoek's primitive microscope - was the beginning of a revolution in our way to look at the world and understand it. The scope of our (admittedly augmented) senses spans now from elementary particles to the remotest regions of space and time, including along the way that awesome marvels that we call cells.
That said, this humble shot portraits a coin operated telescope (a rather pompous name, but I am aware that many people love them, and there is even a group in Flickr dedicated to them) in Montisola, Lake Iseo, Italy*. I must admit that I have not looked into it (just like Galileo's foes...), but I loved the strikingly fresh view on the world offered by its external metal shell - especially how it creates two images of myself: one could go at work as usual, and the other could leisurely wander capturing photos all the time ;-)

This is the Iris Nebula in Cepheus (7-hour exposure)
My latest photo was captured far away from the city lights to reveal the faint, beautiful dust in space.
I hope you enjoy it!

Death Valley's Telescope Peak awaits the warm light of the oncoming sunrise, slowly descending in the desert sky above.
For a short period before dawn you can see the approaching sunrise color descending toward the earth in the sky, while the sky below is still in the cool, blue shadow of the earth's horizon. This effect is maximized directly opposite the soon to be rising sun. Sometimes features in the landscape such as distant ridges and mountain ranges can exhibit that cool lighting, while the sky beyond has those first warm rays of the sun.
There's still an endless supply of beauty in the world. Soon we'll be allowed back out to experience it.

This comet was discovered in 2017.
Minimum approach distance 170,000,000 miles.
Estimated nucleus of 11 miles.
Originated in the Oort cloud, traveling for 300 million years…
“C/2017 K2 (PanSTARRS) is an Oort cloud comet with an inbound hyperbolic orbit, discovered in May 2017 at a distance beyond the orbit of Saturn when it was 16 AU (2.4 billion km) from the Sun... The comet is record breaking because it is already becoming active at such a distance. “ wiki

Another build from the backlog. It was meant to be incorporated in a larger LEGO Ideas project, but there were things I wasn't fully happy with that probably couldn't be solved without starting from scratch. That was something I was not willing to do at that point, so I moved on (or back) to other projects.
This is my take on a telescope piggyback camera setup.
Motorized telescope heads have tons of applications from astrophotography so that you’re not limited by 30 second exposures to panning time lapses. Sky is the limit really (no pun intended).
Here’s what it takes (I suppose):
- motorized telescope. Mine is Meade etx-70at (2-axis panning) with #494 controller and tripod (about $75-100 off eBay)
- cheapo tripod with quick release plate head ($5 off eBay)
- plumbing hose belt (metal hose clamps with screws) errrrr… about $2(?)...
- a day in my dad’s garage (priceless)
On the night of Monday, May 19, all four of the Mauna Kea telescopes with adaptive optics lasers pointed them into the center of the Milky Way galaxy. I knew the Kecks would be doing that, but it was purely by coincidence that Subaru and Gemini also were using their lasers to observe the galactic center at the same time. Gemini is hidden behind Keck II in this image, and its laser is the dimmer one underneath the V of the Keck lasers. The observatories are independent of each other, so this was the first time in memory that all four simultaneously observed the same spot.
A 50% moon followed the Milky Way across the sky, making the imagery a bit difficult. It had been nearly a month since I had a full night's rest, and I pulled four all-nighters in two weeks (including working for 47 hours straight at one point). All that exhaustion finally caught up to me on Monday night, and at around 2 AM I developed the worst headache I've ever experienced. Many thanks to William Montgomerie for driving me down to Hale Pohaku and then returning to the summit to rescue my cameras! I slept six hours after returning to Hilo, and it felt absolutely amazing.
The lasers are used for adaptive optics. Just as heat coming off pavement causes shimmering that distorts details in whatever you're looking at, turbulence in the atmosphere blurs out detail in the stars. The laser is used to track this atmospheric turbulence, and a mirror inside the telescope deforms hundreds of times per second to compensate and produce a sharper image than otherwise would be possible. The galactic center contains many stars in a small area, and without adaptive optics, many would blur together and be impossible to differentiate.

In 1995, the Hubble Space Telescope captured one of the most iconic images of all time, the “Pillars of Creation”. I remember seeing this image as a child and it captivated my imagination. I never thought that I would one day photograph this region of space myself.
The professor is checking his watch, waiting for it to get dark so he can catch a glimpse of the comet. The telescope is from the Re-ment Astronomer's Laboratory set.
Cette photomosaïque de la galaxie d'Andromède, située à 2,5 millions d'années-lumière de la Terre, est la plus grande jamais créée à partir d'images du télescope spatial Hubble. Elle comprend plus de 600 images du télescope et a nécessité plus d'une décennie de travail. La photomosaïque comprend 200 millions d'étoiles, soit une fraction de la population d'étoiles estimée à mille milliards d'étoiles d'Andromède.
« Les régions intéressantes comprennent : (a) des amas d'étoiles bleues brillantes intégrées dans la galaxie, des galaxies d'arrière-plan vues beaucoup plus loin et un bombardement photographique par quelques étoiles brillantes au premier plan qui sont en fait à l'intérieur de notre Voie lactée ; (b) NGC 206, le nuage d'étoiles le plus visible d'Andromède ; (c) un jeune amas d'étoiles bleues nouveau-nées ; (d) la galaxie satellite M32, qui pourrait être le noyau résiduel d'une galaxie qui est entrée en collision avec Andromède ; (e) des bandes de poussière sombres à travers une myriade d'étoiles.

This photomosaic of the Andromeda galaxy, located 2.5 million light-years from Earth, is the largest ever created using images from the Hubble Space Telescope. It features over 600 Hubble images and required over a decade to make. The composite features 200 million stars, a fraction of Andromeda’s estimated trillion-star population.
Interesting regions include: (a) Clusters of bright blue stars embedded within the galaxy, background galaxies seen much farther away, and photo-bombing by a couple bright foreground stars that are actually inside our Milky Way; (b) NGC 206 the most conspicuous star cloud in Andromeda; (c) A young cluster of blue newborn stars; (d) The satellite galaxy M32, that may be the residual core of a galaxy that once collided with Andromeda; (e) Dark dust lanes across myriad stars.

Voie lactée au-dessus du Parc Régional des Monts d'Ardèche
Pour le plaisir de partager, cette image a été prise cet été au-dessus d'une rivière affluente de l'Ardèche. La longue exposition permet d'enregistrer le mouvement de l'eau entre les rochers...
La qualité du ciel dans le Parc Régional de l'Ardèche est l'une des meilleures de France... L'absence (presque totale) de pollution lumineuse, surtout dans sa partie ouest, permet de distinguer des détails très fins du ciel nocturne... On peut ainsi voir la Voie lactée, son "bulbe" (ou "cœur") à l'intérieur duquel se trouvent de nombreuses nébuleuses, étoiles et amas globulaires.

Milky Way over the Monts d'Ardèche Regional Park
For the pleasure of sharing, this image was taken this summer above a tributary river of the Ardèche. The long exposure allows to record the movement of the water between the rocks...
The quality of the sky in the Ardèche Regional Park is one of the best in France... The (almost total) absence of light pollution, especially in its western part, allows us to distinguish very fine details of the night sky... We can thus see the Milky Way, its "bulb" (or "heart") inside which are numerous nebulae, stars and globular clusters.

When you think of Death Valley, what comes to mind?
Beautiful sand dunes, colorful badlands, other-worldly salt patterns... How about some snowy mountain peaks?! On our Death Valley workshop in March, we were treated to some awe-inspiring snowcapped rugged mountains. On this particular morning, a series of lenticular clouds moved in perfectly mimicking the shape of these mountains. This pano ended up being my favorite shot from the morning! Due to high demand, we added another Death Valley Workshop in December 2019. It is almost completely sold out! To reserve a spot or learn more click here:

No evening out in the dark with a friend who happens to be a drone pilot would be complete without throwing an obligatory drone donut over the subject.
It's not easy to get the timing of the circle right but I did like the light cast by the drone on the ground.

This image taken by the NASA/ESA Hubble Space Telescope revisits the Veil Nebula, which was featured in a previous Hubble image release. In this image, new processing techniques have been applied, bringing out fine details of the nebula’s delicate threads and filaments of ionized gas.
To create this colorful image, observations were taken by Hubble's Wide Field Camera 3 instrument using five different filters. The new post-processing methods have further enhanced details of emissions from doubly ionized oxygen (seen here in blues), ionized hydrogen, and ionized nitrogen (seen here in reds).
The Veil Nebula lies around 2,100 light-years from Earth in the constellation of Cygnus (the Swan), making it a relatively close neighbor in astronomical terms. Only a small portion of the nebula was captured in this image.
The Veil Nebula is the visible portion of the nearby Cygnus Loop, a supernova remnant formed roughly 10,000 years ago by the death of a massive star. That star – which was 20 times the mass of the Sun – lived fast and died young, ending its life in a cataclysmic release of energy. Despite this stellar violence, the shockwaves and debris from the supernova sculpted the Veil Nebula’s delicate tracery of ionized gas – creating a scene of surprising astronomical beauty.
The Veil Nebula is also featured in Hubble’s Caldwell Catalog, a collection of astronomical objects that have been imaged by Hubble and are visible to amateur astronomers in the night sky.

NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy’s central black hole. Webb’s powerful infrared gaze produced this detailed image of the Cartwheel and two smaller companion galaxies against a backdrop of many other galaxies. This image provides a new view of how the Cartwheel Galaxy has changed over billions of years.
The Cartwheel Galaxy, located about 500 million light-years away in the Sculptor constellation, is a rare sight. Its appearance, much like that of the wheel of a wagon, is the result of an intense event – a high-speed collision between a large spiral galaxy and a smaller galaxy not visible in this image. Collisions of galactic proportions cause a cascade of different, smaller events between the galaxies involved; the Cartwheel is no exception.
The collision most notably affected the galaxy’s shape and structure. The Cartwheel Galaxy sports two rings — a bright inner ring and a surrounding, colorful ring. These two rings expand outwards from the center of the collision, like ripples in a pond after a stone is tossed into it. Because of these distinctive features, astronomers call this a “ring galaxy,” a structure less common than spiral galaxies like our Milky Way.
The bright core contains a tremendous amount of hot dust with the brightest areas being the home to gigantic young star clusters. On the other hand, the outer ring, which has expanded for about 440 million years, is dominated by star formation and supernovas. As this ring expands, it plows into surrounding gas and triggers star formation.
Other telescopes, including the Hubble Space Telescope, have previously examined the Cartwheel. But the dramatic galaxy has been shrouded in mystery – perhaps literally, given the amount of dust that obscures the view. Webb, with its ability to detect infrared light, now uncovers new insights into the nature of the Cartwheel.

The first anniversary image from the NASA/ESA/CSA James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disc, the makings of future planetary systems.
The young stars at the centre of many of these discs are similar in mass to the Sun or smaller. The heftiest in this image is the star S1, which appears amid a glowing cave it is carving out with its stellar winds in the lower half of the image. The lighter-coloured gas surrounding S1 consists of polycyclic aromatic hydrocarbons, a family of carbon-based molecules that are among the most common compounds found in space.
[Image description: Red dual opposing jets coming from young stars fill the darker top half of the image, while a glowing pale-yellow, cave-like structure is bottom centre, tilted toward two o’clock, with a bright star at its centre. The dust of the cave structure becomes wispy toward eight o’clock. Above the arched top of the dust cave three groupings of stars with diffraction spikes are arranged. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. The dark shadow of the cloud appears pinched in the centre, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the dark cloud. The image’s largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges. At the top centre of the image, a star displays another, larger pinched dark shadow, this time vertically. To the left of this star is a more wispy, indistinct region.]

A scene I stumbled across whilst shooting. This is one of the radio telescopes at the Mullard Radio Astronomy Observatory outside Cambridge.
“NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188.
NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova. “ Wikipedia
