Working under good sky conditions, we captured an exceptional image, something impossible to do just a few years ago: the relativistic jet of quasar 3C-273, showing fine details. The image above comes from the...
Never before had a telescope with a diameter of less than 180 centimeters probed so far into space and time. Media kit available here. Records are made to be broken. This statement is especially...
Mai prima d’ora al mondo un telescopio di meno di 180 centimetri di diametro aveva scrutato così lontano nello spazio e nel tempo: lo sguardo sull’Universo più profondo di sempre mai ottenuto dal territorio...
Imaged the most distant quasar observable at visible wavelengths: its light has traveled in space for 12.9 billion years. Never before a telescope of 350mm in diameter looked so far back in space and...
Fotografato il più lontano quasar osservabile nel visibile, la sua luce ha viaggiato nello spazio per 12.9 miliardi di anni. Mai prima d’ora un telescopio da 350mm di diametro si era spinto così lontano....
We managed to capture the brightest quasar in the sky, 3C 273, and its relativistic jet. The image above comes from the average of five, 300-second exposures, unfiltered and unguided, remotely taken with the...
We report the discovery of the long term, large variability of the optical counterpart of the NVSS J004354+404634 radio source in the field of Messier 31, found during our survey of this galaxy. Our investigations...
On 24 July 2013, the Celestron 14″ robotic unit was slewed to a very distant source, quasar PG 1634+706 with the goal to grab a spectrum and measure the redshift of this astrophysical source. This...
After the very positive results with quasar 3C 273, we tried to get a spectrum of APM 08279+5255. This quasar is shining at mag. 15.2 and is located at a distance of 12 billions...

Few things are able to capture the imagination of stargazers as the idea of distance of a cosmic object. While looking at that likely pale spot of light, so hard to see with their...
Recently, the Celestron C14 robotic unit has been equipped with a SA100 diffraction grating, making possible easy, low-res spectroscopy. After a couple of successful tests, we managed to measure the red-shift of quasar 3C...
