Hi Efendy, Why not leave the SE home? Buy a second hand Dob 6 or 8 inch (pretty cheap) then just take that. Keep your SE in great nick and have your dob as a "sacrificial" scope. Still should last years. (ps I was brought up on a farm just out of Robe and also was deckhand on rock lobster boat there for 4 years in my early 20's. Nice place to fish.
Cheers, Richard
