G'day to all you budding astrophotographers!

I would like to vigorously encourage any and all who are thinking of giving astrophotography a crack. Sure, it's nice to have thousands of dollars worth of precision equipment, but let me reassure you, you don't even need a telescope!

All it takes is some pretty basic equipment, combined with a little bit of tricksy know-how. It really is that simple.

Be prepared though, if you get into this thing, you will get hooked, you will get aperture fever and your wallet will get thinner!

I have penned some pages of basic techniques here (http://asignobservatoryii.com/astrophotographytips.htm), that should get you started as well as give you a reality check, seasoned with some well deserved uppercuts.

Below are a few examples of what can be achieved with basic to advanced techniques in advancing order.

DSLR, wide lens 16mm, tripod, 10 second timer delay, 30 second exposure, brake lights, levels and curves adjust in photoshop.

That's not all folks, there is so much you can do, the sky isn't even the limit!

Cheers and blessings!!

P.S. Mods, would this make an OK sticky to help the new guys starting out?
