You really need to sort out what you want to do, and why, before buying hardware - there's a very good chance you will find what you bought is unsuitable then sell it to buy the right gear. Some even make this mistake 2-3 times.
Start with a scope that is ideally around f/5 (reflector) or less than f/7 (refractor). The question of aperture, focal length and the mount to put it on is determined by how deep your pocket is. At the low end there is this sweet little ED APO:

which could be mated to a cheap little mount that tracks the sky such as this:

The only snag with that is that scope really is SMALL - most observers have bigger finderscopes. Even some eyepieces have larger aperture.
Do do anything significantly beyond what that combination is capable of means spending the best part of at least $3k and more likely $5k.
