On board Bendy Ben from Bunbury ,
.
4 1/2 inch scope ? , what brand are you thinking ? there are many ( how do I put this ??? ) oh well , rubbish scopes out there in this size , trust me but there are plenty of good ones but be very careful before putting your money down , do you have a model in mind ? , let us know if you do . I have an old Tasco red tube 114mm f8 up in Darwin that performs brilliantly on its solid EQ2 mount that I gave to a young up and comer and he just loves it , great scope optically that handles 200x easily when using better 1 1/4 inch Plossl eyepieces .
I would suggest a Celestron Heritage 130p or any of the 6 inch Dobs that either Bintel , Andrews or others sell , great starter scopes .
We are looking at heading down that way around October and if you want we can catch up for a stargaze ?
Good luck and keep in touch .
Brian.
