Where can I find a visible star dataset? I'm trying to do a project for a databases class where I have a user enter their current location and I tell them what constellations/planets/etc are visible in their area. I've seen this data compiled into images, PDFs, and website entries, but I can't seem to find a csv for it. I get that this data is bound to be massive or extremely complex, but I feel like there should be something out there. Any clues?
You can probably extract the data from Stellarium. Also, does it need to be all sky, or not? What Wavelength? If you want an all sky visible catalogue, the United States Navy produced the NOMAD catalog by combining 2MASS, UCAC, and the USNO-B catalog. You could also use the APASS all sky catalog, meant for helping astronomers with photometric calibration.

If you don't care about whether the wavelength is in the visible, CalTech's IRSA has a bunch of infrared source catalogs (the smallest/shallowest one being the IRAS catalog). The deepest all sky infrared catalogs are the WISE sets.

Other good databases to dig in to include the Hipparcos set of parallaxes, or some part of the Gaia catalog.
