Visibility III / V


Of course, the blue snowball was not blue when shooting on the luminance channel alone. It looked very much like it was visually perceptible and can be even more visually interesting.

      Planetary nebula is the remnant of a death star. It could be ring-shaped, disc-like or spread out rather irregularly.

      With the exception of some nearest objects planetary nebulae have a small apparent diameter and they need a rather big instrument to be visible.
