This area in the constellation Pisces contains a lot of very faint interstellar dust.

The faint circular Planetary Nebula Pre 8 (PN-G 143.3-43.2) was discovered by the Norwegian amateur astronomer Trygve Prestgard in 2016. The size of this nebula is about 1.6 arc min. The spectra confirmed that this nebula is a true Planetary Nebula, hence making it the first PN discovery in Pisces. It is also known as the Ghost of Pisces Nebula.

A lot of small galaxies are located around the bright stars Rho Pisces and 94 Pisces: the galaxy cluster Abell 195.
