If anyone is looking for information about a particular variable? I have found a online database of the 1980s edition of the Moscow Variable Star Catalouge. Its has 2000.0 RA coordinates and spectrum, period, minimum, maximum and the type of variable for each star. This website gives links to various parts of the catalouge and it even has extra-galactic variables database.
