Here are the completed towers, joined at the feet. The platform is still not in place yet.

Platform fitted. These ended up gone on and off about a dozen times....... for various reasons.... mostly because of the limited instructions.

The azimuth assembly (I.e. The bit that turns) on the base.

I had thought that the base outer wall was too short, but I then realised that I'd put the wheel chassis beams on the wrong way round.

The mirror finally in place.

And finally, the completed model, with red spikes that represent the lasers. I believe they fire lasers into the sky, somehow measure the light that is reflected back, and somehow modulated the individual hexagon mirrors to correct for distortion from the atmosphere. That is some seriously heavyweight engineering and computing. There's a wikipedia entry here if anybody is interested. https://en.wikipedia.org/wiki/Adaptive_optics

A great sense of achievement now that it's finished. Firstly, managing to obtain all the parts, then making sense of the limited instructions and actually finishing the model.

I am idly toying with the idea of motorising it. However, that will have to wait for a few months while I get back to the BOTY H2R.

Thanks guys.

12 grand for an amateur’s scope! That’s obviously aimed at very serious amateurs! It would be wasted in most of China. You’re lucky if you can see the moon! The pollution is that bad. Hong Kong isn’t much better.
