In islamic calendar, every new months related to new moon. Moeslems do observation before announce new month such as Muharram, Ramadhan, zulhijja, ect.
Yesterday, i visited aceh observatorium to join moon observe even. I did it with friends from kemenag aceh.
Sadly, i can't capture new moon because i don't have a good camera. I only used cell phone camera to capture some images of telescope and i used yi action camera to do timelapsing.
