Does any know of any amateur (but high quality) observatories in Spain where visitors are welcome to use on-site telescopes? There are such places in the US, particularly in the Southwest (Arizona and New Mexico). I know of one boutique hotel west of Madrid that has an observatory with a fine telescope which is available for guest use with professional assistance. If there are others, I'd like to check them out. In particular, I'm interested in lunar and planetary photography using the equipment.

Gracias.
