Hi Johnno,
Thanks for your replies and i'm glad you got the finder issue sorted.
As far as the difference between a 10" & 12" Dob goes about all that changes is DSO's look a bit brighter. Nothing looks any bigger as such.
As for Planets a good Barlow will definately help, but the downside is the object you are looking at will be harder to keep in the field of view.
I haven't used my 12" Dob for months as i haven't been home. Arrived home last night to Atherton just sth/west of Cairns and it's raining anyway

. Looks like it will be like this the whole time i'm home as well.
The other half is happy to see me so i better not complain.
The 6" Refractor and HEQ5Pro live in Weipa for the time being.
Haven't had much luck viewing up there either. Just have to be patient and wait for the wet season to end.
Cheers and happy viewing,
Duncan
