EyesNot visible to the naked eye.
Binoculars (10×50)Just possible from a very dark site, with a nebula filter held to the eyepiece.
Telescope (6–8 inch)Thin, faint arcs with an OIII filter; without one, almost nothing.

For a dark country sky with no Moon. From a city, faint galaxies and nebulae can disappear completely.
