Just quickly doing a mental layout, I'd have to say that the UMa/M39 pairing (as seen from NGC 7082) would be rather more similar looking than our M39/NGC7082 display. This would be due to the much smaller space separation between UMa and M39, resulting in similar sizes as well as apparent magnitudes of the brighter stars. Moreover, the close distance from us of UMa, combined with the already close alignment of M39/NGC7082, would most likely result in a fairly small angular separation on the sky at NGC7082...

I have a freeware program called Partiview (short for Particle Viewer), available from the Hayden Planetarium. I can't recall if the UMa cluster and NGC7082 are both included in the stock package, but I might have added one or both (if that was indeed necessary) in my version at home. I'm curious to examine the apparent separation of UMa and M39 as seen from NGC7082 (because in partiview you can travel where you like!)

BTW, I highly recommend that you install this neat program. The learning curve can be a bit steep, but it's an amazing visualization engine. And you can modify or add all the databases you wish! In certain respects it's only limited by your own imagination.

P.S. I submitted the OB association data that's used by the program...
