Now Philosophical Realists would claim there is a mind-independent Sun, Proxima Centauri, existing as an objective reality out there as real in real time t1.
But the fact [FSK] is Proxima Centauri in real time t1, may not exists anymore, i.e. could have died long ago in real time.
Some Philosophical realists may think this is not possible, but I doubt those who have any knowledge of astronomy think this.
But a philosophical realist can hold the position you have without contradicting their ideas.
As an aside; your argument is based on a realist model that there was a noumenal source for those light waves. That it did exist in the past, but might no longer exist. The very model you are using to demonstrate the foolishness of realists is a realist model of distant stars (which we have no direct contact with) emitting light etc.
But the main point is a philosophical realist can agree with you on this point and still be a philosophical realist.
Google away: you'll find lots of philosophical realists saying the same thing.

When you look at a star, you are looking at the light that came from the star. Because stars are so far away, it takes years for their light to reach us. Therefore, when you look at a star, you are actually seeing what it looked like years ago. It is entirely possible that some of the stars you see tonight do not actually exist anymore.
"their light" noumenon's light.
It did exist, but might not anymore.
Realism
My thesis is philosophical realism is not tenable to be realistic.
Philosophical Realism claims that things and reality are absolutely mind-independent to the extreme that the moon pre-existed humans and will do so even after humans are extinct.
When a philosophical realist [PR] perceive a table out there, a PR will insist there is a real mind-independent table out there
in reality regardless the existence of any mind.
Therefore, when a PR [based on philosophical realism] perceived a star, e.g. "Proxima Centauri" which is perceivable via a telescope, the PR will insist that the star perceived [Proxima Centauri] is a real 'star' in reality
just like the table out there in reality.
People like PH [philosophical realist] will insist, that star [Proxima Centauri] perceived and described is not the real star; PH will insists there is a real star as
matter of fact [the perceived] out there that is independent of opinions, beliefs, judgment and the human conditions [i.e. absolute mind-independent].
But the above claim of philosophical realism is
false, because there is no real star as
matter of fact [the perceived] out there that is independent of opinions, beliefs, judgment and the human conditions [i.e. absolute mind-independent].
What is deemed to be that real star in real time, is an illusion because in the above example, in real time [now], the observed and perceived Proxima Centauri could have been swallowed by a black hole, thus non-existence in real time.
There is a time-gap or Reality-Gap between what is perceived and the supposedly 'the-perceived' which is illusory.
What is real is merely what is based on what is perceived by the mind upon the
emergence and realization [note this]of what is Proxima Centauri as conditioned upon the human-based [mind related] science-physics-cosmology FSK.
Thus, philosophical realism claimed of a mind-independent reality can never be tenable nor can it be realistic.
The light waves that hit the retina and perceived are merely light waves, they are not Proxima Centauri as it 'was'.
Even with light waves, there is still a
time-gap or
Reality-Gap between what is perceived and the supposed 'the-perceived' which is illusory.
My point of using Proxima Centauri as an example is to demonstrate the a
time-gap or
Reality-Gap between 'what is perceived' and the supposedly 'the-perceived' which is illusory.
This
time-gap or
Reality-Gap is applicable not just to stars but to EVERYTHING in reality.
Because of this
time-gap or
Reality-Gap, philosophical realism's absolute mind-independent things and reality [matter of fact] is not tenable, cannot be realistic and it impossible to be real.
Because PH's denial of objective moral facts is based on philosophical realism which is grounded on an illusion, PH's refutation has no credibility at all.
