An obscure one, and very likely with next to no visible objects in it,
but I've always had a soft spot for stuff like this, and nebulae in
general

http://vizier.u-strasbg.fr/viz-bin/ftp-index?/ftp/cats/J_ApJ/639/227

rename catalog.dat to MSXirdc.dat and place it in the Guide directory,
also cut and paste the below and save it as MSXirdc.tdf in the Guide
directory. Dark red brown ellipses to scale and orientation, with
help available on right click.

It's sometimes interesting to see these things crop up visual objects,
both bright and dark nebulae, that are well known places on the sky,
gives an added dimension to their nature.

Cheers

John
