Time for another progress report.
I have now finished both the mirror cell and the upper cage, complete with guitar tuners for the wire spider.
The secondary holder is also completed. It is an 'enhanced' version of my current minimalistic holder, meaning that the position of the holes for the wires provide an improved geometry of the wire spider. Also the split down the middle means I can in the future run power directly through the wires to the secondary if I'll ever need to install active dew control. Currently this has not been necessary, a fan seems to do the job, but this is a 100mm secondary mirror compared to my current 70mm so I thought I'd better future proof it.
I'm happy with how the big Moonlite focuser sits nicely just between the ply rings. Everything on it is easily accessible while the weight and dimensions of the structure is still kept to a minimum.
Finally, everything has had numerous applications of Sikkens marine grade finish.
