Re: Stellarium And Object Data Question
An OIII filter is a very narrowband filter that blocks almost all light except in the roughly 500nm range.
As for figuring out which filter is best for a specific object, I don't think Stellarium is suited for that.
I've found what I usually do is decide what I want to image, then go somewhere like Astrobin.com, search for that item, find others that have imaged it and look at their details to see which filter they used.
Eventually, you'll learn the differences between reflection nebulas, like M42, good with broadband filters (LRGB) or emission nebulas like IC434 (The Horsehead Nebula) That shows up better in

Re: Stellarium And Object Data Question
A narrowband Oiii filter is for imaging only. It passes an extremely narrow band of wavelengths, usually requiring longer exposures. I suspect that this is what AstroBee was referring to.
There are also Oiii filters made for visual use. They have a much broader pass band than a narrowband imaging filter. They are used for enhancing
An Oiii filter will, of course, work best on targets that are rich in Oiii. Planetary nebulae are rich in Oiii. Emission nebulae have Oiii to a lesser extent. Galaxies would be poor targets for an Oiii filter.
