3: T40 Observatory

We continue to the second telescope, first I thought this was Tamm's private observatory that I had read about. But Eric at Uppsala University told us that this is the T40 observatory, it has an 40 cm Cassegrain telescope used to do electro photometry. Tamm's private observatory was behind the villa and a rectangular building without a dome.

Observatory building no 2:

Already from the observatory below we came from we saw the next observatory. All three observatories are very close to each other.

This observatory has a 40 cm Cassegrain telescope Eric told us. He told us also that it was very small, only two peoples could be inside the observatory at the same time.

Even this observatory has a real functioning dome.

The entrance to the building, not very practical with stairs up to the building. When in use at night it's completely dark and heavy equipment to transport to and from the observatory.

Eric told us that this observatory was built at the same time as the observatory for the Schmidt telescope. But it didn't take so long time to built so it was finished in the 1950s.

The observatory building has a diameter of about 3 meters.

To have an observatory with a real dome is only a dream for most amateur astronomers. Here are the lids that cover the opening for the telescope. They slide on rails left/right when they opening.

A view to the South down the hill and both of the two newer telescopes are in sight.
