Odyssey Rebuild - 3 pole truss

Progress not as fast as I'd like but still coming along.

Completed the mirror box, transport poles and worked on spider.

Trimmed the hexagon on the spider so that the central obstruction is now totally due to the secondary mirror and spider vanes.

Mental4Astro again has given some excellent advice re size of secondary cage. Fixed the clamps to the secondary cage this afternoon and placed it on top of the transport poles. The image in the secondary mirror is the centre of the bottom of the mirror box which I deliberately didn't paint black. It was very reassuring to see this image. The spider is only tentatively placed on top of the secondary.

To offset or not to offset the secondary that is the question.

Attaching a few additional photos.
