First light with the 585mc. Managed to get a little bit of data on two targets before the weather turned. Decided to shoot the Monkey Head for reference with the 533.

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

Done, something completely slipped my mind.

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.
