OBJECT DESCRIPTION AND IMAGE SESSION

Discovered in 1946 by Rudolph Minkowski, this lies in the nebula was formed from the death of a bright star, however there are still some uncertainties about the star parent star that gave birth to this planetary.

Dr. Luis Miranda from the Instituto de Astrofísica de Andalucía stated: "...The nebula presents a multi polar structure and several pairs of bipolar lobes at different orientations...These lobes most certainly formed at different times and likely involved a binary progenitor - in particular with mass-transfer of multiple episodes of mass ejection along an axis where orientation changes in time..."

I started imaging SH2-71 from rural skies and finished the Ha shots from my light polluted backyard.
