Customer Statement


“We have recently purchased the 1.40 m telescope „Milankovic“ from the ASA company. The telescope was installed in May 2016 at our Astronomical Station Vidjevica and only a few days later we have been convinced that both the tracking and image quality are excellent…

We are very happy with our decision to select ASA as our partner and are very satisfied with the perfect work they have done both on mechanics as well as on the optical quality of the 1.40 m telescope that we purchased from them…”
