On the night of Deceber 30/31 Comet 8P/Tuttle will graze the outskirts or even pass in front of the galaxy M33. Since the brightness of those two bodies is comparable (6.5 for the comet and 5.7 for the galaxy) it is well worth it to give it a try and take a memorable photo.
I would love to see the photos you will take in Serbia.
Clear skies!
