Sounds like a 114mm Synta Newt clone (F=900, f/8 ). Maximum useful magnification 228x. Description written by a camera salesman....

It's still an OK starter telescope for the right price.

And a name

Model is Celestron Powerseeker 675

.

Sounds like this scope with a department store blurb and 12.5mm eyepiece instead of 10mm eyepiece.
