@tfb Unless if it was a rogue planet coming from interstellar space. That's what made this question so intriguing.

@B--rian, according to https://in-the-sky.org/data/planets.php "Venus recently passed behind the Sun at superior solar conjunction. From Varna, it is not observable – it will reach its highest point in the sky during daytime and is no higher than 7° above the horizon at dusk.". Is the site just wrong or am I misinterpreting stuff?

@B--rian or if you're suggesting it's just a spec of dust on the lens - maybe it's possible. But I also took a couple of photos before and after that and they don't have the same "spot".

Welcome to astronomy SE! I am rather certain that is an effect of the lens - in any case a zoom-in of your object would be helpful, see also https://astronomy.stackexchange.com/questions/43684/what-is-that-donut-shaped-object-i-see-in-my-telescope

The official way for a question like this is close-as-duplicate your question rather than answering it - please do not feel dishearted by that.

What is the blue circle right of the Moon and just on the top right of the hole between the clouds?

I tried to look at [a planetarium](https://in-the-sky.org///skymap.php?no_cookie=1&latitude=43.22&longitude=27.92&timezone=3.00&year=2021&month=5&day=25&hour=21&min=37&PLlimitmag=2&zoom=109&ra=15.10718&dec=-26.27860&skin=0) (time and location included, no idea about the azimuth).

I'm pretty sure this is simple [lens flare](https://en.wikipedia.org/wiki/Lens_flare).

While lens surfaces in cameras have antireflection coatings that strongly reduce reflections, they are not perfect. A very bright small spot like the Sun or Moon or a bright streetlight will result in near-mirror images opposite the center of the image.
