comment How do telescopes “zoom” and change angle of view?
A refracting telescope would need many lenses for good zooming capability. Amateur scopes usually only have two or three lenses to reduce chromatic aberration. With amateur telescopes you can buy zooming eyepieces, which let you vary the FOV.

comment What is the temperature of outerspace?
@RyanMcGaha From the linked WP article: The baseline temperature, as set by the background radiation (from the theorized Big Bang), is 2.7 kelvin (K).

comment What can be seen with a 4.5" telescope
Large Messier objects like open clusters will show lots of stars. The Orion nebula will seem like a grey, cloudy patch. The core of the Andromeda galaxy will also be a cloudy patch. The large globular clusters like M13 will appear as lots of stars in a sphere.

Then you can definitely take on the planets, since you will have about a meter of focal length. You should Start out with a 10mm eyepiece, and later buy a Barlow lens, or better: buy a good 8mm or 5mm eyepiece. The last may be expensive or not very suitable anymore for your telescope, though.
