From Dylan O’Donnell.

I reveal yet another closely guarded secret of the astrophotography elite they don’t want me to share in case you start beating them at competitive astronomy. #thegalaxycode #hagb #ghabg #eggystars #spacejocks #datmag20tho

Also Thanks to Per Einer Ljokjel @PerEinerLjokjel for the astrometric reduction.. apologies for spelling your name wrong in the video!
