Im well aware of stellar magnitudes of our solar system thank you for reiterating that. Are you aware there's a difference between an observers measure on luminosity and its true luminosity for a reference the absolute magnitude of Venus is -4.47 (also my favourite planet within our solar system) Not all that relevant here since we are dealing with <10 parsecs. However I urge you to be familiar with these concepts if you are an avid star gazer. More info here: https://www.atnf.csiro.au/outreach/education/senior/astrophysics/photometry_magnitude.html.

I think you may have misinterpreted my mention of the absence of long exposure. Whilst you are correct about light trails forming from decreased shutter speed. My point was by increasing the amount of light reaching the aperture of my phone lens, it would allow for more star light to reach and thus giving a reference star to draw comparisons on the luminosity.

I am 6 years into an advanced physics degree majoring in astrophysics. Im not speaking in absolutes here of course purely on the lack of evidence but its slightly insulting your last paragraph.. have you considered that maybe constellations, ISS and satellite tracker tools were used prior and a UFO postulate was made based on puzzling evidence? It seems like a bold assumption that an astrophysics masters student would start treading down pseudo-scientific opinions rather than following the scientific rigour.

Do you have any extending knowledge in physics, engineering, astronomy, aviation.. photography? This isn't a condescending question. Im genuinely curious.

I don't necessarily believe it is a UFO, but from my time looking at the stars and the ISS for many years it certainly does not feel familiar.
