Thanks for all the advice, now for my next question.
I am building an observatory on my property, should I build a cement pillar or build a steel pillar filled with concrete to stop vibrations?
I am an ex-boiler maker so i can fabricate and weld.
I am still a little confused about my choice in scope, I have read in other articles that a large Dob 12" + would be better for Photography and Observation as long as i had dark skys (which I do, the nearest city is 300kms, and the nearest town is 50 kms i live on 100 acres in rural N.S.W)
Please help im more confused than ever! i have $4000 max budget to spend on the scope (i got a fright when i found out how much the 11inch HD celestron scopes were). I really want something that is dual purpose with GOTO functions, which i will mount to a pillar in the center of the observatory. Am i being unreasonable to think that $4000 will get me a scope that will suit deepspace and planet observation?
Thanks again in advance
