How do I convert star HIP numbers to SAO numbers?

I use Stellarium on my PC to orientate the night sky, and for star hopping - in this software package all the stars are given HIP numbers. However, my Celestron uses Nexstar which wants an SAO number entered to find a star. So at the moment, other than for the more common/brightest stars (which are listed under Nexstar), I cannot instruct guide my telescope to go to other stars that I find on Stellarium since I don't know how to convert a HIP star number to an SAO star number.

Does anybody know how do do this?

You can query the SIMBAD database

SIMBAD Astronomical Database

and select either the basic or identifier link - enter the HIP identifier in the field (include the letters HIP) and it will give you a page detailing the object - including several different identifiers if known i.e HIP, SAO etc..

Thats how I have done it in the past in an ad-hoc way. I dont know of a method or plugin to allow this directly from Stellarium.. of course I havent checked to see if there is an SAO catalog available for stellarium which might be a better bet long term...
