Remote Astronomy at Observatorio del Pangue
We still offer a service of hosting telescopes or private observatories for those stargazers who enjoy accessing to the Southern sky in optimal conditions. Don't worry for technical support or high speed internet, we provide it all. Below is an example posted by Evasope, our most recent customer. For more information and availabilities, just ask us.

Astrophotography at Pangue : a perfect galaxy

NGC4565 (Com) is not only a fine example of an edge-on galaxy, it is a stunning sight in large telescopes, spanning for some 15 arcmin. through the eyepiece, that is half of the apparent size of the Moon !...

Lately, at the Observatorio del Pangue...

First, you arrive at Santiago de Chile...

...then you want to travel North and meet our clear skies !

In this column we display some of the most relevant news, pictures, or feelings happening around the observatory.

For a complete information on the place and the proposed programmes, you can visit our "facts" pages, listed at the top of the blog.

...and lastly, as to check if we really are as famous as the below picture suggests, don't hesitate to visit us, we'd be glad indeed to receive you...


March, 5th, 2021 : First Pass of Apophis...

...and certainly not the last ! Some asteroids deserve special attention, and this one is among the top of the list, not because of its characteristics (merely 350 meters across), but because of its orbit, that brings it close to Earth, too often, and maybe too close...
On the evening of March, 5th, Apophis cruised off our planet, at a respectable distance of over 16,000,000 km (some 10 million miles), that made a good opportunity to watch it, safely ! The apparent magnitude of 15.5 was bright enough to allow us to see it visually through our telescopes and, why not, to capture its relatively fast motion among the star field (apparent motion was estimated at 3.5 arcsec. per minute) in the constellation of Hidra.
We took a series of pictures at intervals of 2 minutes only, and still they clearly show a tiny dot shifting from one to another : that's Apophis ! Here we display some of them, with the asteroid identifyed by the red mark: (North is up for all the views)
Click on the pictures to enlarge, and watch them in a presentation mode as to see the motion effect
The picture below shows the path of the asteroid on that night (roughly from 22h00 to 03h00, local time), with the previous position circled:
And here is another series of pictures, spanning approximately an entire hour:

Apophis will make an extremely close "flyby" on April 2029, approaching at only 36,000 km from Earth centre (that is, some 30,000 km from the surface!), then again another close pass in 2038... In first instance, there was a small probability of collision for 2038, now definitely ruled out by the most accurate calculations. However, these same calculations arise a risk of collision for 2068, although we may not worry yet : the orbit of Apophis will be affected by the gravitational field of Earth during its 2029 flyby, hence the definitive trajectory cannot be established until then...

Astrophotography at Pangue

There is much more to see in Orion than the Great Orion Nebula : here we captured the NGC1977 nebula, located 1 degree north to its great neighbor, a nice gem by itself when properly observed in detail and in good conditions...

"Night and Day"... the frame is complete !

We used to post pictures of the Sun setting behind the dome of the CTIO (Cerro Tololo Interamerican Observatory, our immediate neighbor), an event that happens twice every year, at the exact same dates. But on last January 15th, we've been granted with the setting of the Moon behind that same dome, and this is far more unusual as, for a given observing spot, it repeats every 10 years only... So now we got the two pieces of a unique collection !
For the record, here is again the picture of the last Sunset on Tololo, taken on the evening of 2020, November, 3rd. : same dome, same size of the disk...
So here is the frame, complete...
