Bassano Bresciano Astronomical Observatory

Welcome to the remoted Astronomical Observatory of Bassano Bresciano website

The Observatory Bassano Bresciano is self-financed and self-built a private observatory located in the homonymous town of Bassano Bresciano, in the province of Brescia, at an altitude of 58m above sea level. The observatory is catalogued with the code 565 at the Minor Planet Center and the code 22 at the Institute of Theoretical Astronomy in St. Petersburg, is also included in the list of observers protected from light pollution by the law of the Lombardy region n. 17/2000.
Activities stated in the 1983, when they were published astrometry measurements on the Minor Planet Circulars, obtained using a small reflector telescope with a diameter of 15 cm. The current observatory was launched April 29, 1989, the main instrument is a Schmidt telescope with a mirror diameter of 42 cm corrector plate of 32 cm diameter and focal length is 1000 mm. The telescope is on an equatorial fork mount. The instrument is housed on the first floor of a purpose-built under a dome with a diameter of 5 meters.
Since commissioning, the telescope is equipped with computerized pointing. Over the years changes and improvements was made in both the mechanical and the electronics. Today the observatory is fully automated and remoted. It can work in automatic through the night without operators presence and be remote-controlled. For a long period the main research interest has been the astrometry of minor planets and comets, this activity led to the discovery of four new planets definitively catalogued. In recent years the observatory has diversified its activities: it does photometry of asteroids and variable stars, is part of the Italian Supernovae Search Project (ISSP), the Italian program to search for supernovae, and is part of Gamma-ray Coordinates Network the telescopes network that receives event notifications GRB by satellites can detect the gamma ray burst. In the research of GRB in 2012 was able to photograph an event that occurred at a distance of 10 billion light years.

Mercury planet will transit on sun disk. Mercury will be between Sun and Earth exactly in the line. Last time it was possible see this event was in the 2003

transito di Mercurio

We'll observe the event with a telecope in our observatory. All people will be able to follow it from our web site

29 Jannuary 2016

We have participated, with French and Belgian astronomers amateur, to an astrophysics research for new Exoplanet discovering. It is a planet rotating around a young double star in the bull constellation. An academic paper was sent to the prestigious magazine Astrophysical Jurnal It can be read at this address.

Planet transiting in front of the start decreases its light only 2 cents of magnitude as you can see in the above graph we get with our telescope in the night 15 January 2016

Published statistic for year 2015

Discovered nova in M33
As part of the search for ISSP, the Italian program for research of supernovae, we found a "nova" in the spiral galaxy M33, which is 3 million light-years, which belongs to the local group

Two presentations at provincial astronomy meeting

Goal 50 !
Same days ago we have reached the goal of 50 variable stars discovered.
It is a binary star EW type in the Delphin constellation, two stars are rotating one arround to each other in only 12 hours and 44 minutes.

Venus and Jupiter conjuntion

Activities for new Newton 250 mm. telescope building was started
Following our OpenSource philosophy, all project will be available to astronomers amateur interested in. For this purpose two blogs are opened allowing see step by step developing.
Mechanical part developing is available here, electronic part developing is available here

"Eclipse of Sun"
The image was taken with a digital camera and lens MTO 500, in a outdoor lesson with 3 classes of Manerbio primary school

"4 steps into the universe"
Also this year public meetings at Palazzolo Sull'Oglio library

Published statistic for year 2014

It have been started activities for the replacement of the electronic control for the 25 cm Newton telescope, in line with our OpenSource philosophy all the wiring diagrams and software will be available to homebuilders amateur astronomers that will want to use them. For this reason we opened a blog, where who is interested, can follow step by step the development.
Blog is avaliable at address

Two presentations at provincial astronomy meeting

September 2014
The research program VeSPA is 4 months old, in this time we have discovered and recorded 16 new variable stars:
11 close binary stars
3 Cepheid RR Lyre-type
1 semiregular
1 Mira-type variable
5 of these we were able to assign the name

Close conjunction between Cerere e Vesta

May 2014
Started VeSPA project for automatic short period variabile star discovery
3 nre binary stars discovered

Discovered a new binary star

Stelle senza nome

I nomi delle stelle sono belli:
Sirio, Andromeda, l'Orsa, i due Gemelli.

Chi mai potrebbe dirli tutti in fila?
Son pi di cento volte centomila.

E in fondo al cielo, non so dove e come,
c' un milione di stelle senza nome:

stelle comuni, nessuno le cura,
ma per loro la notte meno scura.
