Thank you all for your comments. I take great heart in them.
Adrian, the poles being used now are a totally new set of carbon fibre poles. These new poles are custom made for me, and are significantly more rigid.
Mark, to show EVERYTHING in the very first post would leave room for further surprises!
A light baffle or shroud is not mandatory, particularly when it comes to ultralights. However, I will be offering not one, but two different 'shroud' solutions. To make any one item 'standard' would be presumptuous and shows a lack of understanding of the different priorities one person has to the next, and of the product. Having one solution is fine. Having two gives more choice and flexibility.
Marana comes in at a tick over 21kg. The single heaviest component, the mirror box, is just over 10.5kg - this can be very significant for those people where carrying heavy weights is a concern, as it is not necessary to carry the whole stowed configuration all at once. More cut-outs could have been made to the mount, and even the mirror box, but this would have left the primary mirror unacceptably over exposed. Like mentioned earlier, "stuff happens". When it does, it's those little thoughts that can make the difference.
