In most cases, neutron stars and black holes seem to be accompanied by a brown or red dwarf if in a binary system. The rarest binary star arrangement I stumbled across once was a neutron star (or a black hole) with a main sequence F class star.

Has anyone ever found a multiple star with more than one stellar remnant? For example, binary white dwarf, BH+neutron star and so on? I cannot find any. Are systems such as these exceedingly rare or simply not generated?

Most of the time when two stellar remnants are in a binary with each other, usualy they have been around for millions of years, and therefore are really rare sometimes because they're probably some of the first stars in the galaxy, unless the galaxy is really old. :D

Not sure how rare this is, but a 5 star system I found a little while ago.  That is the absolute most I have seen so far in a single system.

Most neon planet?  Certainly has to be the most pink atmosphere at least!

Largest ring system discovered so far.  This is a real object not a procedural one.

They are freaking huge!

I don't have enough posts to post a screenshot, but that thing is equivalent in size to its planet

I found a pretty luminous star. (RS 0-6-145117-1621-3145-0-0-177 A)
Yes, I am not sure if this is just normal or not.

HIP 20553 is also a real star with the most habitable worlds (One having a habitable moon)
