ScopeDome 3M V3

The ScopeDome 3M V3 is available in both manual and fully motorized versions, controllable via PC and even over the Internet. It is the result of more than a year of development by ten different companies, each analyzing every detail to create an observatory designed down to the finest specifics.

The dome’s unique shape sets it apart from any other amateur observatory. It was designed not only to protect instruments from weather conditions but also to provide more interior space, especially when carrying out visual observations or astrophotography sessions inside the dome.

Thanks to its spherical design, it offers greater volume at human chest height – precisely where other observatories, with their vertical side walls, can feel restrictive.

The ScopeDome 3M V3 is built to deliver perfect protection against all weather conditions: strong winds (up to 140 km/h or slightly higher), snow thanks to reinforced ribs, and heavy rain with rapid drainage through specially designed channels.
