About:
NGC1342 is an Open Cluster located in the constellation of Perseus. The estimated distance from Earth is 1,170 light years. This cluster overlaps nebulous objects LBN 718 and LBN 719. VdB 18 is a small diffuse nebula, visible in the constellation Perseus.It identifies exactly halfway between the two stars Algol and Epsilon Persei, the first blue-white star well known for its variations, and the second a blue star of fourth magnitude to the south of Eta Persei, or alternatively about half a degree northeast of open cluster NGC 1342, is illuminated by a blue star cataloged as HD 22114 and also known as the variable star V496 Persei, being a variable Alpha2 CVn and shows itself as a distinctly bluish haze of color. The cloud extends in particular to the south, which has an elongated structure parallel to the star. This nebula is located beyond the northern edge of the large cloud known as Perseus and is connected with a system of dark nebulae directly related to the California Nebula, visible to the southeast. Throughout the region are active phenomena of star formation, evidenced by the presence of young stellar objects, estimated the distance of the system is about 900 light-years from the solar system ....
