What is the diameter of Celestia's virtual magnifying telescope?

Here is the maximum magnified view of Pluto from Earth orbit in Celestia 3D.

Is it possible to measure or estimate the diameter of Celestia's virtual magnifying telescope?

Added after 4 minutes 51 seconds:
If I'm correct, the angular resolution of a telescope is given by θ=1.22λ/D where D is the diameter of the
aperture.

This is Hubble's view of Pluto from 2003:

This is the magnified Pluto from Celestia:

So does it mean that Celestia has the magnifying ability of the Hubble Space Telescope?

I think it is obsolete now.

We should use the Kilometer Space Telescope in Celestia 3D instead.

What do you think?

that really is not a Hubble image but a processed one by "mark buie at.al "

this is the raw hubble images

Thanks for the raw images!

Actually this is the Celestia image in "raw" form:

I think the difference is 3 times more pixels in Celestia.

So Celestia has a 7-8 meter wide "telescope".

It seems that Celestia is a little bit better than the James Webb Space Telescope.
