I had downloaded the PSR 1257 file,put the "psr1257.jpg" in the med res texture directory,put the "psr1257.3ds" in the models directory.I even put the pulsar log(with the planets) in the extrasolar ssc entry,but when I see the star catalog,I saw no pulsar.And when I input psr 1257 in the Celestia search,there is none.
I don?t know how can I introduce pulsars to Celestia.The star catalog ssc entrie is not easily modified because it appears it is criptografed.Someone can help me?
