Hi Cameron,
Sunglasses ?
Well at least you will look cool.
Except ... its usually night when using it.
Hmm!
Unlike most self professed experts, it is impossible to say if it is any good on this description alone.
Although the anomaly of the tube length and focal length does sound a bit unusual. "synthesised"
This may be a reasonable instrument, but I would not expect to pay over $100 for that - unbranded. It will be pot luck.
Safer bet is to go with a known and trusted brand, Meade Celestron Skywatcher, Orion, even Saxon, to name a few.
Focal length determines magnification. (mag=foc lgth / eyepiece mm)
Width (or aperture) determines amount of light gathered.
Amount of light determines what best magnification can be expected (aperture in mm x 2) but poor atmospheric conditions will greatly reduce that too.
Equatorial mounts can be a pain in the neck for visual observing.
Probably better and bigger bang for buck to go Dobsonian.
Best advice is to go to a local observing session and have a look through others scopes.

Oh, by the way
Hope to see you soon
