Polar plot centred on magnetic north [message #90819]

I've been trying to create a polar plot centred on magnetic north with no succcess. This is simple enough in geomagnetic (e.g. map_set, /stereo, 90, 0, -90, limit = [45, -180, 90, 180], /continents, /isotropic), but when I try and centre the plot on magnetic north it becomes seemingly impossible to set correct limits. Doing
map_set, /stereo, 82, -72, /continents, /isotropic, /horizon
works, but I see way too much latitude; I'd like to limit it to about 45-90 MLAT. I'm not sure if the e_horizon keyword would help me since I can't find out what can be called through it.
Any advice would be appreciated.
