NGC 253 Sculptor Galaxy under Sydney Skies
Took the opportunity to image a galaxy ( NGC 253 Sculptor Galaxy ) in Sydney during the new moon period as we had 2 clear nights in a row on Tuesday and Wednesday nights.
Haven’t imaged a galaxy in Sydney for quite a while
I’ve watched “Cuiv the lazy geek” on YouTube image galaxies under a white zone Bortle 9 in Tokyo using hundreds of 30 sec and 60 sec subs. His galaxy images are excellent
Used a similar philosophy with plenty of short subs imaging in suburban Sydney under Bortle 7/8 skies and 2 storey homes either side of me with exterior lights blasting my yard all night
Pretty happy how the image turned out
