An undiscovered planetary nebula, a juicy neighbouring neutron star system and a moment of inattention (talking to the lovely missus after initiating the FSD, radio on masked the sounds of the jump, next thing: Bang! Emergency drop.)

Yes, that's a binary of ELWs orbiting a neutron's secondary star, that also had a WW and a HMCP, both terraformable.

Doh! Moments of inattention are the explorer's enemy. All my modules hovering around 70-80% now, with some (cargo hatch @40%) even lower.
Only 19.9KLys to go!
