One of the best resources of an amateur astronomer is an astronomy club -- if you are lucky enough to live close to one. But not all are created equal.
The Atlanta Astronomy Club has been a bit of a disappointment -- I showed up for their meeting in September, only to find the building locked. I found out later you have to arrive early, before the security guard locks the doors. I showed up in October, only to find out later they had no meeting that month. The club is large enough to become impersonal - but I highly recommend them because they are large enough to afford to bring in wonderful speakers and programs. So stick with them for a while!! They maintain a great dark site and astronomy village. They have several telescopes and observing programs.
The Northwest Georgia Astronomy Association is a very hospitable group. They are an informal group where there are no dues and anyone with an interest in any aspect of astronomy is welcome and 'belongs'.
The Southern Cross in south Miami is a great group and has a great outreach into the community by having solar viewing set up on Sundays at the Miami Zoo. Their star party in the Keys is one of the best.
The South Florida Amateur Astronomy Association has a great observatory (Fox) and is very welcoming to visitors, guests and new members.
When I started in astronomy, I had no mentors to help me learn how to use a telescope or find the Ring Nebula. My first contact with other astronomers was at a viewing area for a solar eclipse in 1971. It was sponsored by the Astronomical League, which is a wonderful resource for those of us who are "at large" members who are not close enough to a good club.
If you can't join a local club, the Astronomical League is well worth your time.
