Why weren't they grouped with the old versions to make comparison easier?

Is the processing completely identical? Well, except for the calibrations.

Almost identical. But you could have pulled a bit more from the background, while the stars are bloated because the seeing was worse than with the 533. I'm focusing more on the transitions from light to shadow and how the shades blend.
