I use a combination of SIMBAD, online sources and galaxy map to find these objects.
This specific object is part of the PSR series. If you type PSR into galaxy map and press return, it will take you to the first listed object. Press return again and it will take you to the next one. Keep doing this and you will eventually end up at Circinus Pulsar in-game. While the EDSM site says it was named by the community, it is actually listed in-game as Circinus Pulsar.
There are a number of catalogues included in the map. I've concentrated on XTE, GRS and OGLE objects in the past. Others concentrate on the Messier, NGC, HD and HR catalogues. There's some Kepler catalogue entries in the map as well.
