Barnard 173 (Dark nebula)
R/B-band color composite image from the Second Digitized Sky Survey (DSS2), measuring 10 arcminutes across.
From South El Monte , Barnard 173 is visible in both the dusk and dawn skies. In the evening, it will become visible at around 18:34 (PST), 27° above your north-western horizon, as dusk fades to darkness. It will then sink towards the horizon, becoming tricky to observe after 19:20 when it dips 21° above your north-western horizon. At 05:19, it will return to an altitude of 21° above your north-eastern horizon, and reach an altitude of 23° before fading from view as dawn breaks at around 05:35.
