If you were in a spacecraft at the right point in space, could you look out the window and see, for example, the Horsehead Nebula as it appears in that famous photo?

Question

Or would different light wavelengths etc render it invisible/completely different from how we recognize it from our space photography (for want of a better term)?

Answer 1

No. The human eye is not sensitive enough to pick up the very faint light from that nebula (or indeed most nebulae, especially any colours as the human eye is even less sensitive to colour). Cameras can take long exposures which let’s them pick up more light from faint objects allowing us to capture images of them.
