OBJECT DESCRIPTION AND IMAGE SESSION
BlDz 1 is a circular symmetric planetary nebula located in the western area of the constellation of Centaurus. The nebula has it name after astronomers Adriaan Blaauw (ESO); I.J. Danziger (ESO) and Hans-Emil Schuster (La Silla, Chile), The discovery was published in August 1975 (*).
A blue plate taken with the ESO Schmidt Telescope was use to reveal its structure.
The object presents circular shape with weak lobes without a central hole. There appears a distinct secondary shell just outside the main nebula.
Difficult to image from my Bortle 8 location, however the OIII flter was somehow useful to contribute with some contrast and data to the RGB channel.
