The light we got last night from #M27 began left the nebula around 756 AD. That year, Abd al-Rahman I declared Córdoba independent as an Umayyad Emirate. Meanwhile, Pepin the Short was expanding the Carolingian rule across Europe, setting the stage for Charlemagne’s empire.

Here are the sky and weather conditions during our #astrophotography session. Dark skies, low wind, and moderate humidity gave us a pretty decent view of the object — even with the waning Moon rising around 1 a.m!

Yes, this was our second attempt. Back in August, clouds and wildfire smoke over Spain and Portugal (what a horrible summer here...) made it impossible to get anything good. Last night we finally made it, and here are the result of over 3 hours of exposures with our Classical Cassegrain telescope.

The #DumbbellNebula, named after that gym gear you lift once and again in a gym, is the second planetary we got this summer. Its twin lobes stretch north-south, surrounded by a faint outer halo. At its center lies the largest known white dwarf, whose violent past gave birth to this stunning remnant.

Forgot the technical data of our work! What you see is the result of stacking 47 exposures of three minutes each, taken with an astromodified DSLR camera, which allowed us to capture the reddis halo surrounding the object, at ISO 200

Last estimates from SIMBAD places #M57 about 2560 ly away from here. Light in our picture began its journey in the 6th century BCE, when Tarquin the Proud ruled Rome. The rape of Lucrecia by his son sparked the revolts that ended the monarchy and led to the foundation of the Roman Republic.

Take a closer look at the center of #M57. Can you spot the faint star? It's the white dwarf at this nebula's heart. Its hard to resolve with equipment of the level of ours, and it only becomes visible under excellent observing conditions, like those we had last night.

Discovered in 1779, M57 is the remnant of a dying star that expelled its outer layers into space. What remains at the center of this kind of objects are dense white dwarves, stellar cores roughly the size of a planet! #Astrophotography

The light we captured last night left #Messier3 about 33,900 years ago, when Neanderthals were living their final centuries on Earth (AI generated depiction). Soon after, they vanished mysteriously, giving way to Homo sapiens. The exact reasons for their extinction remain a topic of debate.

The blame wasn’t on the unusually high temperatures for a May night in Extremadura (Spain), but rather on the atmospheric turbulence (clearly visible on the camera screen) and the high concentration of dust and pollen in the air. Still, we managed to partially resolve the object’s core.

To capture such an small object, we brought out our most powerful weapon, our 1848 mm Classic Cassegrain. We relied on autoguiding — though looking back, that might not have been the wisest choice having on account the environmental conditions of the night. Just 7 of the collected frames were valid.

Spanning only 18 arcminutes in the sky, M3 is a dense globular cluster made up of over half a million stars — some among the oldest in our galaxy. Although hard to resolve without a powerful telescope, M3 is one of the most beautiful globulars and can be relatively easy to spot under dark skies.

Photons from galaxies have travelled for a long, long time! This light comes from the Oligocene, a cold, dry epoch in which forest turned grasslands, early mammals began to thrive, and giant walking birds populated the Earth. Antarctica's ice caps started forming around this era. #Astrophotography

The session ran technically smooth. It was our first approach to plate solving: combining it with a custom Excel spreadsheet we built to calculate the mount offset, we got the object in the field of view on the second try.

We tried our best last night but we only got nine frames, 12 minutes long each of them. Total exposure time rounded two hours.

The whirlpool galaxy (Messier 51) is a magnificent spiral galaxy in Canes Venatici. It's interacting with a smaller one, NCG 5192 (image left), and due to this dance both of them had their shapes altered. You can spot it with binoculars only under extremely dark skies. #Astrophotography #M51
