Visiting the radio telescopes in Humain (Belgium)

By -

During the weekend of September 9 and 10, it was possible to visit the radio telescopes in Humain (Belgium).  It was the first time since the site was opened in 1953 that a visit was possible.  The station is used by the Royal Observatory of Belgium.  A solar interferometer of 48 radio telescopes was build in the 1960s.  The telescopes are not used anymore since 2001.  All telescopes are have a diameter of 4 meter and are located at a height of 293 above sea level.  

A few larger telescopes are still in use at the site. 

Enjoy the pictures!







Location: Humain, 6900 Marche-en-Famenne, België

On August 30, 2023 we installed an ASA AZ800 telescope in the observatory at work, at the  Institute of Astronomy  of KU Leuven .  The telescope will be one of the telescopes of the MARVEL project, an array of four telescope we will install on the Roque de los Muchachos in La Palma,  It was a very rainy day, but we managed to put the telescope in the observatory.  Enjoy some of the pictures!

Interstellarum Deep Sky Atlas

For Father's day, I got the field edition of the  Interstellarum Deep Sky Atlas .  In the past, I always used the first edition of Uranometria 2000.0 by Will Tirion, which was published in 1987!  I was always very happy with the Uranometria and I always preferred the first edition over the second edition.  I never took the book outside, but I made a copy of every page which I put in a sheet protector.  I took the pages in a big folder outside to starhop through the skies.    The Interstellarum Deep Sky Atlas comes in a nice sturdy slipcase. The last years, I mostly observed from home (Bortle 5), so I mostly observe bright objects.  Since last year, I added a SkyFI 3  to my Argo Navis / ServoCat so I can use SkySafari to always have a map on my phone or my tablet.  However, a real star atlas has a nicer overview, which is very useful when observing.  Under dark skies, a good star atlas is really needed to find the faintest objects. A nice card with the legend of the atlas The nice t

Adhesive felt on the Obsession

The interior of my Obsession's mirror box is not entirely black.  I am unsure whether it has always been this way or whether the black paint has faded over time.  I still had a lot of black adhesive felt lying around from a previous project.  I applied this adhesive felt to the mirror box of the Obsession telescope, making it considerably darker than before.  This will undoubtedly improve the contrast of the faint objects I intend to observe.  Part of the mirror box with adhesive felt, a part is still with the original paint.
