VdB 40 is a tiny reflection nebula in the constellation Orion. It is separated just 16’ from the bright star Bellatrix (γ Ori), which makes its observations and imaging very tricky. The nebula is illuminated by the 9.2 mag star HD 243588. At the top center can be seen a part of the dark nebula LDN 1595. The ring shaped formation, as well as the surrounding circle are reflection from γ Orionis. Below is a higly magnified crop of the nebula itself :
