mag 5.25 skies but very little in terms of nebulosity...

So to the naked eye, 30UMA is a 4.5-4.6 mag star? Cheers for clarifying!

So I'm checking some stars out on Simbad, but the pages for them only state spectral type, parallax & coordinates... No mention of brightness, do I have to do something to get this info?#

Cheers for the help,

In Simbad's "basic data" look for "Fluxes"

Spectral type: A3IV C ~ Fluxes (5) : B 4.607 [~] C ~ V 4.560 [~] C ~ J 4.698 [0.238] D 2003yCat.2246....0C H 4.568 [0.027] C 2003yCat.2246....0C K 4.378 [0.021] C 2003yCat.2246....0C

The letters B, V etc are the different filters used when measuring the magnitude. V is closest to the human eye's spectral response, so that's the one to check - in this case given as 4.560.

Something else: When Trying to determine my NELM, should I be thinking about "Extincted" magnitude or the non-extincted magnitude? Or should I just look for stars at or near the zenith?

There is no universally agreed "rule" on how to do this: it's a subjective estimate. Some people count the briefest glimpse as a positive sighting, others would want the star to be steadily visible, at least for a few seconds. Ideally the star should be at zenith but as long as it's high in the sky it will do. If you're under a hazy sky then a star of magnitude 4 might look as faint as one of mag 5 under a clear sky, but you would record your limit as 4 (if that's the faintest you can see).
