You know that the SOFIA flying observatory takes images from the universe that are at times indistinguishable from those supposedly taken by the Hubble telescope ?
Yes, the crucial part of what you say is, "that are
at times indistinguishable from those
supposedly taken by the Hubble telescope
They are quite different instruments.
Stratospheric Observatory for Infrared Astronomy
The telescope
SOFIA uses a 2.5 m (8.2 ft) reflector telescope, which has an oversized, 2.7 m (8.9 ft) diameter primary mirror, as is common with most large infrared telescopes.
. . . . .
The telescope looks out of a large door in the port side of the fuselage near the airplane's tail, and initially carried nine instruments for infrared astronomy at wavelengths from 1–655 micrometres (μm) and high-speed optical astronomy at wavelengths from 0.3–1.1 μm.

SOFIA is primarily an infrared telescope, though it can observe over the visible range.
Hubble Space Telescope
With a 2.4-meter (7.9 ft) mirror, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared spectra. Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely high-resolution images, with substantially lower background light than ground-based telescopes. Hubble has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time.

The primary mirrors are a similar size and SOFIA observes from above most of the earth's atmosphere, so it can take excellent short exposure visible light images.
SOFIA does not provide the long-term stable platform that Hubble does, so SOFIA cannot be used for very long exposure deep-space photographs.
Hence some SOFIA photographs might be comparable with some Hubble photographs, there is a vast difference in capability.
