What to expect?
So what will you see through a telescope as compared to
the pictures found throughout the internet?
The below picture of M42 (the Orion nebula) is the
typical thought a new comer may have on what the wonders of
the sky may look like...

In reality the brightness, clarity, and colour saturation
of the above photo only results for taking multiple photos
of the object, taking flat and dark frames(??), combining
these photos through various technical processes in an
application like Photoshop, and then you see a result like
the above.
Depending on viewing conditions and telescope aperture,
the image below provides an example of what M42 may look
like through a telescope...

If it happens that you live in a light polluted location,
you may also then have a reddish glow to the view.
Planets can be very impressive. At low magnification
definition of the planets is better. Higher magnification
can improve the viewing size of the planet, but definition
of the planet (for example, the rings on Jupiter) is
reduced. Funny compromise which you would think would go the
other way.
