The telescope moves into the hut! And: Yet two more players!

Claudia and Bruno Wagner are visiting (with their children). As everybody else, they also have to help setting up the telescope. Here we move the 16" Cassegrain from the 'schuur' (the barn - where it was stored) to the telescope hut. When looking at the image we ask: What are they carrying - a heater? - a beer barrel (from Egger Brau)?

The telescope weighs about 45 kg. I have built a wooden construction to hold it in the correct height to let it be mounted to the telescope mount.

At least I thought it is the correct height... After we put the telescope on the holder, we find out it is 16 mm too high. Urgh! We take the telescope down again and I reduce the height of the 'table'.

On the next day, we put the telescope a second time on hte wooden holder and connect it to the mount. Here you can see it freely swinging - and I find two more problems...

The declination spring block bumps into the worm gear protection when the telescope is moved higher than 40 deg declination! Checking with old photographs of the set up telescope I realise that we did not think about whether the declination drive should be on the sky end or on the ground end of the telescope wedge. Of course we mounted it at the ground end, but it should have been on the sky end. We need to turn the telescope around - tomorrow...

Another problem is that the declination scale bumps into the worm. This is something I remember the previous owner telling me, but I forgot... However, that's the part of the sky I'll be most interested in to use. So this needs to be fixed too.

This photograph shows that the declination scale should be about 20 mm away from where it is right now...

And digging through my scrap metal box I find a piece of aluminum tubing which is 23 mm thick and has the right diameter! Lucky me. I mount it and at least the 2nd issue is fixed. The first issue - turning the 'scope around - will come soon.
