The truss tube for Dobsonian telescope… and surroundings

SOLIDITY’ = PREROGATIVE ESSENTIAL OF LATTICE The need for unity in the transportability of Dobson telescopes (characterized by a reduced frame ingeniously essentials despite the large aperture of the primary mirror Newton) has meant that the optical tube of such instruments, must obviously having a larger diameter for just contents the big primary mirror, It could be replaced

Dynamic Re-balancing with bungee cord, Of Dobson “light weight” telescope

In support of the fact that the balance of light Dobsonian (and not), It can be done dynamically as an alternative to the use of counterweights, I do narrate here my recent experience to rebalance with elastic rubber my Dob250F5, After adding optical finder 6×30 weight of 265g.
