| Notes:* | This has become a popular field to image; however, there is confusion as to the actual positional identity of the object known as "vdB 142". According to the "Atlas of Galactic Nebulae", by Th. Neckel and H. Vehrenberg, the object they designate as GN 21.35.1.02 (vdB 142) is a faint blue reflection nebula to the northwest of the star near the eastern end of LDN 1105 (dark lane). The sinuous dark lane LDN 1105 is also known as the 'Elephant Trunk' nebula. The object with the bright rim and embedded dark lane is not vdB 142. See here for my 1993 14.5" Newtonian image taken on hypered Tech Pan 2415. See here for an color image that nicely shows the fan-shaped nebulosity of vdB 142 |
