VdB 1 (LBN 578, or Magakian 3) is a small reflection nebula in the constellation Cassiopeia. It lies a few arcminutes to the south-east of the bright star β Cassiopeiae (Caph). The distance to VdB 1 is estimated to be 1,600 light-years. Two more nebulae can be seen at upper right from VdB 1. They show loops and outflow features associated with the energetic process of star formation. Within are extremely young variable stars V633 Cas and V376 Cas. There are various jets, coincident with many HH objects: HH 161, HH 162, associated with the nearby V376 Cas, and HH 164, the source of which is V633 Cas (see the annotated mouseover). At about five o'clock from VdB 1 is situated the dark nebula LDN 1265. It is barely visible due to the bright light of Caph (β Cas). Below is a highly magnified crop:
