NGC 1788 (also catalogued as VdB 33, Bernes 98, Ced 40, DG 51, LBN 916, LBN 203.49-24.76, Magakian 90) is a reflection nebula visible in the constellation Orion. It lies about 2 degrees north of the star β Eridani, in the western part of the constellation. It has relatively small size and can be observed with a powerful telescope or long-exposure. The nebula reflects the light of nearby stars, in particular of a star of the tenth magnitude, located in the northwestern sector of the nebula. To the south, NGC 1788 is crossed by a dark band, known as LDN 1616; the distance of the nebulous complex is estimated at 1470 light years from us.
