We were woken up by the sound of water sprinklers on the lawn outside, and our bikes getting a free wash. Having bits of ice breaking off my bike and hitting me at 120km per hour a short time later was a novel experience.
Up the N1 to Matjiesfontein where last year we had been happy to pay R80,00 for a couple HOT cups of coffee and scones at the Lord Milner Hotel, then a left turn up the road to Sutherland. We were here during a storm of note this time last year so missed the observatory. The weather is clear now so we got there after booking in at the "White House" on the main street opposite the Police Station, a very biker friendly place of accommodation.
Lunch was at a cafe over the road and then up the hill 18km to the South African Astronomical Observatory. It has actually a collection of various types of optical observatories set up by various countries since it is one of the best areas in the world, with low light or other pollution, and low radio wave pollution. And COLD because of the altitude.
A tour took us a couple of hours and it was most interesting, especially the Southern African Large Telescope. This is possibly the best optic telescope in the world with the biggest mirror ( there is another with the same size ). One snippet is that the mirror, which is made up of 91 cells ) cannot be washed since that would scratch the surface, so over about six months the cells are removed, their aluminum surface removed, and then they are recoated with aluminum to the original high quality.

The mirror within a lattice of beams. All the beams are straight, the apparently curved ones are reflections in the mirror. The curve can be seen if you look carefully. The darker segments are clean, the brighter ones dusty and scattering the light.
Then down to Sutherland w to fill the bikes, and supper at the White House.
There is a cold front on the way so we are leaving the Cape just in time. We aim to stick to the tarred roads since the local dirt roads have a lot of sharp rocks so it would be a risk to use them with Anakee tyres.
