How to use SIMBAD? or other sky viewer
I would like to do some viewing of the sky using an online viewer.
I have tried simbad, though haven't figured it out very well. Is there a tutorial video anyone knows about and or is there a better site? primarily for the moment, I'd like to be able to pick a sky direction, then select an object type, then view the sky directed at the sky direction showing all of the types in that field of view. for example, I wanted to search for quasars around ngc1222. I found 2, one of which is LBQS 0303-0251 -- Quasar But I was only able to plot one object at a time and couldn't control the field of view. It appears there are 2 QSOs within the 2 arc minute field the system gave me, both of which I think are right in the center of the galaxy. How could I be able to see a distant quasar through the light of the center of a galaxy? I tried to select otype = QSO and found 2 objects, but then I couldn't get them to plot along with the NGC1222. Any suggestions? Is there an easier viewer I should use that can show me these objects? I like the details in SIMBAD if I could just figure out how to get plots and select a list of object types to plot. Thanks, rt |

For quasars, you'd probably be better to query a quasar catalog, and SIMBAD and NED don't keep up very well with the latest discoveries. You can query the "half million quasars" catalog at http://vizier.cfa.harvard.edu/viz-bi...source=VII/273 |
