Soph03 that is odd, maybe things are different at your location, do you know the jingle twinkle, twinkle, little star, how I wonder....? "For most people, the concept of a twinkling star is quite romantic, and conjures up memories of one of the most famous nursery rhymes of all time."
Thanks for the reason to look this up. Now I learned something new, the scientific explanation for the difference.
https://www.skyatnightmagazine.com/space-science/why-do-stars-twinkle (accessed11/26/2023):
"If you look up at the stars on a dark night, you might notice that these bright points of light appear to twinkle. In actual fact, stars do not actually twinkle: they just appear to do so from our perspective on Earth.
Our atmosphere reaches about 10,000km up from the surface of the Earth, and within the atmosphere air gets blown around, while hot air rises and mixes with cooler air.
Stars appear to twinkle because as light from those stars passes through our atmosphere, it is bent and distorted by varying temperatures and densities of air.
There is even a scientific term for stars' twinkling, and that's 'atmospheric scintillation'. This is the astronomical term for those quick changes in the apparent brightness of a star (more on this in our guide to stellar magnitude) or even the colour of a star produced by the aforementioned atmospheric irregularities.
Similar effects are seen in the way our view of an object might be distorted by heat rising from a hot radiator or roaring fire, for example.
It is possible to capture these effects of atmospheric distortion in an image, by photographing the changing colours of a twinkling star. For more basic stellar astrophotography, read our guide on how to photograph the stars."
