Minkowski 1-8 in Monoceros was the Deep Sky Challenge Object in Astronomy Now
Magazine for Feb 2020
It proved to be quite difficult to track down.
I couldn't find a positional reference in TheSky6 for PN G210.3+1.9, but the
finder chart in the magazine (but not the coordinates) implied it had a position
that corresponded to planetary nebula PLN 210+ 1.1.
Centering on PLN
210+1.1 coordinates RA 06 53 31.404, Dec +03 12 13.64 (Epoch 2000) no planetary
nebula could be seen at that location (absence confirmed by reviewing
spectroscopic images. However some 3.8' to the south there was
a small smudge of light (unnamed in TheSky6) at RA 06 53 33.79, Dec +03 08 26.59
(Epoch 2000) that has a spectrographic signature of a planetary nebula.
This is believed to be Minkowski 1-8.
