Description

Yet another slab of time  joyfully  spent on this Northern wonder  during a Southern Queensland inclemet Summer!
This high quality  data set is yet again  and magnanimously provided free to all by Lucomatico. 
Luke Newbould - https://www.youtube.com/watch?v=bozLTpEhpgU
https://www.astrobin.com/users/LukeNewbould/  Luke has a great tutorial on how to process it  from start to finish!!
The star that created this ball of super  heated matter is SAO20575 . it is a yellow -white super giant at a high 36200 kelvins and is 23.7 times the sun's diametter in size.
The stars total energy out put or luminosity is 862979 times the sun's !!It has a mass of 49 solar Mass. This is a massive star.
I believe that Sky Safari notes are incorrect labeling it as a planetary nebula .
The actual bubble is estimated to be 11000 light years distant  with a diameter of 10 light years.
Awe and Wonder folks
