I tried to give you the best answer to your question on the basis of all the parameters you proposed, including one which you didn't -
good to excellent optical performance. A telescope is simply an optical device to facilitate an enhanced view. In the case I cited it was for imaging, which could also easily be extended to visual.
Not my definition....
telescope
ˈtɛlɪskəʊp/Submit
noun
1.
an optical instrument designed to make distant objects appear nearer, containing an arrangement of lenses, or of curved mirrors and lenses, by which rays of light are collected and focused and the resulting image magnified.
BTW - No offence taken.
