Hi there
I'm a newbie from Brisbane and thought I'd say hello, and ask a few questions.
I'm using a secondhand 10" collapsible dob which I bought from an ad here - it came with about a dozen eyepieces, filters, and 1.25 and 2 inch barlows.. so far it has been great. The seller was awesome and showed me around the scope at night when we met - which was fantastic. I've also learned a lot by reading posts on this forum..
So I've been observing for a while and have got a few questions....
This dew thing... how long roughly will a dew shield keep dew off the secondary on a really wet night? I'm wondering if a heat source is worth looking at or whether a dew shield is enough - having to travel out of town to dark skies it would be great to know it can be kept out one way or the other.
Was also wondering, how good are the high end eyepieces like the televiews... They're expensive - but are they worth it?
Cheers
Josh
