Hacking the tube
This is more of a note to myself
The focusser was in the origional position (far too close to the primary mirror) so I cut a new hole for the focusser 55mm closer to the top of the tube.
After collimating images are quite a bit better. No more vingetting at 0.001 degrees off axis.
Seeing was only ~2 arc seconds, Trapesium stars looked about 1:4 size to seperation.. but at low altitude. Straight up was ok still need to get collimation bang on, not 100% happy right now, although a focoult measurment showed the optics generally were still on the nose.
Next: electronics boxes!
