Perhaps you are thinking of a different term related to telescopes or astronomy?
Could you please clarify your question? For example, are you asking about:
* Specific types of telescopes? (e.g., Hubble Space Telescope)
* Parts of a telescope? (e.g., hub of a mirror)
* Astronomical objects? (e.g., Hubble's Variable Nebula)
Let me know and I'll do my best to help!
