My younger sister is a senior in high school who's going into astronomy studies, and I want to get her a good gift for Christmas

My sister is an incredible student. She's in a ton of AP classes, getting top of the class, and she's getting ready to apply to a ton of higher end colleges, some of which she's more than likely to get a scholarship for. She's interested in astronomy and idk if this is an unoriginal idea but for Christmas I want to get her a telescope. Not a toy one for kids but something halfway decent that she'd appreciate and use. I don't know if a telescope is a good idea or if there's something else someone like her would appreciate. Link some good telescopes or if there's a better idea for a gift tell me. Thank you.
