    Hi..
    and welcome to the forum!
    Since you live in Atlanta a computerized goto telescope like the Nexstar line is probably a good choice. Light pollution can make finding things with a manual mount (like a dobsonian) a
    challenge. But if you plan on traveling to a dark site to use your scope a dob gets you more bang for your buck. Bigger is always better for visual astronomy.
    Just so you know some advertised uses of telescopes are not 100% truthful. I started with a 5SE and know they say you can do astrophotography with Nexstars.
    While technically true, you will never get the WOW amazing pictures you see people post here. The mount limits the length of exposures you can do.
    There's basically 2 types of mounts.
    ALT-AZ which moves up, down, left right.. Nexstars and dobs use these mounts. They have advantages for visual astronomy.
    They are easier to set up, align and use. Also easier on your back when looking through an eyepiece.

    Equatorial mounts only move/ track in one direction. To do actual long exposure AP you have to have an equatorial mount. But they are heavy, harder to set up (or at least more time consuming) you have to polar align them. You also can get into some funky positions trying to look through an eyepiece. They're generally more expensive too.

    As far as actual telescopes, OTA's (Optical Tube Assembly) a reflector is always cheaper and gets you more bang for your buck generally (dobs and newtonians).
    A reflector on a ALT-AZ mount is called a dob. On a equatorial mount it's called a newt.

    SCT's like the nextars you are looking at a kinda the swiss army knives of telescopes. For the most part certain telescopes are "better" at certain things. Planets / DSO's.
    SCT's are decent at pretty much everything.

    Like Keith said there's really no buying guide. Alot has to do with personal preferences. What you want to view. AP or no. There's just so many variations.
    This a bit outdated but might be some help
    Recommended Telescopes for Beginners by Price Range

    The best thing right now is do some reading.. ask questions. Think about what you are most interested in viewing. Where you will be viewing / imaging from. Portability issues..
    Take your time and don't rush to buy anything.
    Hope I helped a bit!!

    Being someone unfamiliar with telescope equipment this may be a silly question, but I don't know the answer. Is it possible to take a Dobsonian telescope and put it on an Equatorial mount?

    The 6SE is a nice telescope, but if it's useless for astrophotography, as much as I like it I'll still skip it entirely.

    The term Dobsonian refers to the mount that the telescope is mounted on. It is an alt/az base that you sit a Newtonian Reflector on. It allows you to point it up down and left to right. On Dobsonian telescopes, the optical tube is almost always a reflector type tube.

    You can attach a reflector to an eq mount, but it is important to decide what your main objective is when it comes to telescopes. If your main interest is in AP, then there are a lot better ways to go than mounting a huge reflector on an EQ mount. If your main interests are visual, then a Dobsonian telescope may fit the bill.

    I would suggest getting in touch with the Atlanta Amateur Astronomy Club. You can go with the to their monthly observing parties and see telescopes of all types in action. The members will be most happy to explain how the work and let you look through them. They will give you some pointers and help you decide how to break into this hobby. It can be a daunting process at best.

    Thanks for the advice. Before I joined up here I actually visited the AAC website and poked around there a bit. I looked at the calendar and I couldn't really find much in the way of detail as to when they host their viewing parties, and the "Current Status of Next DSO" is a red octagon with a hand, whatever that means. I also don't know if anyone can just show up to a meeting or if you have to be a member.

    I'd be more than happy to pay the membership fees, but I'm more interested right now in figuring out what they're all about.

    I probably didn't explain it well before but, for some reason the same reflector can be called 2 different things depending on the type of mount. A reflector on an ALT-AZ mount is a dob. The exact same OTA on a EQ mount would be a newt. I guess the scope is always technically a newtonian reflector but only called what it is on an EQ mount.. confusing I know.. lol
    You technically could (probably) mount a dob on an equatorial mount at a later date.. however if you got say a 10" dob you'd have to buy a mangus eq mount to hold the weight.
    The entry level eq mount like an Celestron Advanced VX, or it's equal, an 8" OTA is about all it can handle for AP. Weight is a big issue for astrophotography.

    The 6SE 't useless for AP. It's just isn't capable of true long exposure AP because of the mount.. not the OTA. You can still get pretty cool pictures but you will be limited to stacking lots of 30 second , or shorter photos. You could always put it on an EQ mount later.. that's what I did

    I started with a 5SE and did AP with it for 6 months or so. Then I bought an EQ mount to put the 5SE OTA on. It just so happened I got a deal on my mount and got a newt included for 100.. a 6" newt. That ended up being a blessing as I really like my newt.. But I image almost exclusively.

    The problem is anything smaller than 8" might be dissapointing for visual.. aperture is semi irrelevant for AP..
    Most people (including myself) have more than one telescope..

    If you have a budget it might help narrow down possibilities
