Morphology
The meaning is directly and compositionally derived from 'reflect' (to send back light) + 'telescope' (an instrument for viewing distant objects): 'reflecting telescope' straightforwardly means a telescope that uses reflection (mirrors). The present‑participle adjective pattern ('-ing' form modifying a noun) is a common, transparent construction that a B1 learner who knows both words will readily understand.
Etymology
Reflecting telescope is named for how it works: a big curved mirror inside the telescope 'reflects' light to make a picture, instead of using lenses that 'bend' light. So the word reflecting points to the mirror action, and the name tells you the instrument uses mirrors to collect light and show distant stars.
