This image of vdB123 was taken from my remote observatory in Texas (Bortle
scale 1) with an AGO 12.5" iDK. At the same time, I also captured
this object using a 160mm refractor from my home observatory. See
the image below to compare.
vdB123 is the blue reflection nebula in the center of the image. The whole area is heavily obscured by intervening dust, giving many of the stars an artificial red hue.
