However, if you're ready for the telescope, my advice is to spend as much money as your budget has on getting the biggest aperture you can buy.
More light = more better.
Auto-tracking is nice, but learning how to find objects in the night sky is a fun and worthy exercise, and if you have a big aperture you'll actually be able to see the things your telescope points to.
A few things to keep in mind:
* You're not going to see DSOs (Deep Sky Objects, like nebulae and galaxies) from the middle of a major urban area. You need access to a dark site. (Search for "light pollution map") Planets are easy to see from anywhere, cities included (though the viewing is always better the darker the sky is).
* Many objects in the night sky will look like little fuzzy gray spots to your eyes, no matter how awesome your telescope is. Don't expect a Hubble experience from a 6" scope (or 8, or 12+).
* Don't expect to take photos through your telescope, either. You might manage to get some cool shots of the moon (which looks _amazing_ in a telescope, btw), but true astro photography is a whole 'nother beast (both fun and expensive).
With all that as background, I'd recommend a 6" or 8" Dobsonian if you've got the budget. Something like an Orion Sky Quest XT8 or XT6.
My favorite book, by a light year, is "Turn Left at Orion". It'll help you find thousands of cool things in the night sky, and it's great for beginners on up. — https://www.amazon.com/Turn-Left-Orion-Hundreds-Telescope/dp...
