GAR's Merz-Dallmeyer 162mm

Historic refractor of the Gruppo Astrofili Rozzano: a 162 mm G.&S. Merz objective from Munich on a J.H. Dallmeyer mount from London.

The historic refractor of the Gruppo Astrofili Rozzano (GAR), in the 7 m dome of the Civico Osservatorio Astronomico di Rozzano, inaugurated in May 2023. The 162 mm objective is signed G.&S. Merz in Munich; the mount and the finder are signed J.H. Dallmeyer, London. GAR dates the instrument to the late 19th century, around 1870. It was found abandoned in a private home in Vigevano, has come down to us without structural changes, was functionally restored by ARASS Brera and is protected by the Soprintendenza in Milan.

I used it with the TeleVue 2× Barlow and the colour ASI224MC for an image of Jupiter in September 2023.
