Object Note

By mid 1970?s, the Swedish astronomer, Claes Bernes, observed different nebulosities in the area and originally termed Be 157 as a small reflection nebula, with a diameter of 1? shrouded in this complex area of absorption, together with some other bright nebulae. This small irregular object, also catalogued as Magakian 782, is in fact the small nebulosity surrounding the variable star V 709 CrA (GSC 07421-01890), of magnitude 11.3-11.7, situated in (19h 01m 34.8s; -37? 00' 56.6"_J2000.0), between NGC 6729 and IC 4812. It was wrongly located, with an error of almost 2 arcminutes in its original publication ?A Catalogue of Bright Nebulosities in Opaque Dust Clouds?, (C. Bernes, 1977).

Later on, because of reasons which are not clearly stated, the term for this small nebular object (Be 157), was used to refer to the whole area.
