The only native Welsh astronomy terms that I am aware of is 'Caer
Gwydion' (Gwydion's Fort) for the Milky Way. He was a magician and one of the main chararcters in the fourth branch of the Mabinogi. Also Caer Arianrhod for the same (another prominent (female) figure from the same branch). The dictionary of The University of Wales gives also Caer Eiddionydd for an un-named constellation. It would not be unreasonable to assosciate these characters with older deities.
