Surprisingly well, even in the full moon, subjects in the deep sky can be photographed, here Lyra's ring fog with a 15-minute exposure. Even a white dwarf stands out in the center of the ring fog.

Nebulae
- Planetary nebula
  
  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.
