Yes they are beautifulBtw a new nebulae engine upcoming in 0.981 and new ones will be much more detailed and beautiful. Donno if old nebulas will stay.
but they are procedurally generated, they dont repressent real objects.
whats the problem? right now you have more than 100 real nebulae and many are repressented (kind of) realisticly from every angle
(ofc all nebulae look like their real images.)
