Hey Nomad,
haha tell me about, the amount you end up forking out in acesories is just crazy
I have only taken my new 10" out a few times and have not recieved any dewing around our area.
However having said that with my old scope 4.5" newt EQ I did experience dewing quite heavily at my dark sky location at Terry Hills.
I think when the season changes we will see the full extent of it.
PS: if you live close by, let me know if your interested in meeting up some place for a observation session.
Cheers,
Ash
