Because someone got me one, not looking a gift horse in the mouth, just want to know what I can expect to see being that it will probably be cloudy for the next month...

Looks like it can view Galaxies, Star Clusters, Nebulae, the Moon and Planets

The mount is a tricky design for a begginer... but it should be OK...

I had a scope very similar to that when I first started. It was a good one. Do a little digging and get some info on collimation. The f ratio is pretty high, so it shouldn't need a lot to maintain it, but the mirror is small enough that if it's off by a little bit, it can make a bigg difference.
You might consider replacing the finder with a Telrad or similar item. They run about 40-45 bucks and will probably be more useful in the long run. You could run both though.
One thing I noticed on the site which is wrong is the YES under Astrophotography. It has no motor drive, meaning no tracking, meaning any picture longer than about 1/1000 sec will be streaked. This limits you to the Moon and Polaris. Also the mount may be a little light for photos.
For straight visual observing, it's a good scope. Try and get a copy of the book Turn Left at Orion. It's an awesome guide written for scopes that size, with sketches of what you'll see. Not a big pretty image taken with some monster scope, but a pencil sketch of how things look in a 2-4 inch scope from the middle of a city.
Bundle up, take it out and enjoy.:)

The tube appears to be too short to be a true 4.5 inch (114mm) Newtonian having an f/ratio of f/8.8. This leads me to believe that it may by a Jones-Bird design, which by necessity incorporates a correcting lens system. Generally speaking, it is better to avoid this design.

Nope... no correcting lenses, just a big mirror, a little mirror, and an eyepiece.

Look again, down inside the focuser drawtube. There's a barlow/corrector down there. It's the only way they can get a 1000mm focal length in a 500mm tube. That lens also helps to correct the scope's spherical mirror.
They aren't a bad scope for the money and they're a good enough scope to start with. I started with something very similar. Enjoy it.

This design allows the manufacturer to use a cheap, easily manufactured spherical mirror and a less robust mount since the OTA is shorter and therefore less heavy.
