Hi Christina,
Here's a way to use the Data Base Power Search (DBPS) to get a list of the Cepheid variables. SkyTools recognizes 3 types of Cepheids, classical, beta and delta cepheids so you'll need to search for each one separately. Here's an example of how the DBPS can be set up to search for classsical cepheids brighter than 15 magnitude:
You can repeat the search for beta & delta cepheids to get all 3 types. To limit your search to stars in the Milky Way is more complicated. Do you mean stars in our galaxy? You could try limiting the search to selected constellations containing the Milky Way or set a limit on the distance in lightyears to exclude extragalactic stars.
Hope this helps,
Phil S.
Greg, that's a very nice tutorial. Well done!
