If an observer were transported near the Ring Nebula, how would its visibility change compared to Earth observation?

It would dominate vision with structure and color

The conditions under which we view nebulae from Earth involve light traveling millions of light-years, resulting in extreme diffusion and faintness, regardless of whether we are on the surface or in low orbit like the ISS (where atmospheric turbulence is removed but distance remains). However, if an observer were magically transported to a location immediately adjacent to a nebula like the Ring Nebula, the situation would be drastically different. At that proximity, the observer would effectively be immersed within the light source. The light hitting the eye would be overwhelmingly intense, structured, and highly concentrated, causing the object to fill a significant portion of the visual field and allowing both high-resolution detail and the true vibrant colors to be perceived instantly.
