Reaching the skies

© Cities and Skies (

The Dwingeloo RT is an iconic telescope that has studied the Milky Way for over 50 years. It made important discoveries, like revealing the flattening in the rotation curve of our own galaxy (one of the first arguments for the existence of dark matter), and mapping the distribution of hydrogen clouds all over the skies. The DOGS survey revealed a nearby galaxy behind the obscuring clouds of the Milky Way in 1994, which is known today as Dwingeloo-1 (see e.g.

We felt we should capture the telescope together with its main target of study. The picture was taken on the night of 17-18 July 2021, after Moonset (first quarter). But first, we managed to chase away some young folk who were partying outside in the picnic area at midnight. (They showed quite an interest in the telescope itself and knocked down the old wooden gate. They left when they realized we are watching.)

We combined 100x30s images taken with ISO800, to capture faint details of our galaxy. For the foreground telescope image, we used a shorter exposure. Sony A7III on a tripod with Omegon Star Tracker, 24mm f1.4 GM lens.

Amazing result for @LOFAR and Westerbork radio telescopes! Astronomers combined both telescopes and discovered that a simple binary wind cannot cause the puzzling periodicity of an FRB. The bursts may come from a magnetar, results published in @Nature
