Up for sale is my
10” Newtonian reflector on a Dobsonian mount with Crayford focuser, Telrad, laser collimator + accessories; a “Bintel BT 252 Premium” bought new in January, 2007 from BINTEL in Sydney. There is nothing defective about this scope, only I am looking to change to a smaller scope more suitable to my needs. I am also including a few accessories to compliment it.

This is a wonderfully dynamic scope with considerable aperture, even for advanced users. All my equipment has been kept indoors away from the elements and my puppy! It is all under 2 years old and has been properly cleaned and maintained. The difference between my equipment and the same newly bought equipment is negligible. Also, the price of new 10” dobs has since gone up by $100-$200.
Asking price: $600 negotiable
PICKUP can be made from Rozelle in the inner-west of Sydney, 10 minutes from the CBD. I am on school holidays at the moment and am thus available any time of the day in January. I do not think it would be practical to post/ship this scope, unless anyone can convince me otherwise. Payment can be made by cash on delivery or bank deposit beforehand.
Cheers!
