no filters. could it be dew ?
I have used this lens before in a more open space on the ground and it's been fine. Here I am on a balcony. i also see similar artifacts on my 24-70mm shots at 24mm on that night.
Tamron 24-70 f2.8 at 24mm f4 ISO 79 16x15seconds stacked in Squator and then i just did some adjustments in DXO to bring out the rings.
Maybe some odd reflections from my balcony??
