TRO+tube+assembly+design

The tube design will be an ultralight design. Basic requirements will be:-


 * Plywood will be used extensively as it is cheap, strong and easy to work with.
 * The trusses will be aluminium square poles as in the TROK design but of smaller section. Supplier will be Aalco http://www.aalco.co.uk/
 * The upper section will be a shallow cage rather than a top ring. This will give support and protection for the secondary
 * The mirror box must be no higher than 200mm
 * The top box must be no higher than 200mm
 * A low profile focuser will be used
 * The secondary will have a minor axis of 150mm
