Perseus 4 – Ostium Tenebris

This small black hole (around 2.75 solar masses) at the end of the Perseus Transit region is a rarity in this region of low star density and a good beacon to the vacuum that awaits you if you continue to descend the Perseus arm to the Tenebris Region. At 35413 ly from Sol and 38046 ly from Sagittarius A*, you can play with the effects of gravitational lenses on the distant light of our galaxy.
