7: Lid

With most of the details figured out I can start to design the lid.

Lid:

The small rectangular opening downwards left is for the optical sensor (home sensor).

The big rectangular opening is where the off axis guider will be placed. So far just an empty space for it, the details comes later.

The lid from inside. A rim around the edge make it light proof, even if it's dark outdoors when using it it comes a lot of lights from all control LEDs on the equipment. And it's never completely dark at the night either.
