Bortle class 8-9 Target Magnitude Limitations

[Nikolas74]

Hello ,

I live in the south part of Athens and according to the City Light Pollution Map my place lays on the Bortle scale 8-9....

My question is what is the limit magnitude of targets that I can image ?

I am using already Narrowband filters by Astrodon 3nm (Ha and Oiii).

I am using Stellarium that gives you a hint of targets magnitude..

Thank you

Nikolas.
