They used 189 sensors at 16MP each. So we could do the same if we mounted 189 K5's together.

Makes me wonder how they came to choose a 16MP sensor and not higher? Must be a sweet spot there between resolution and tonal rendering.

But how many autofocus points does it have? And do they spend enough on marketing?

Give it a try: Some astronomers are already using up to 48 Canon lenses at a time - from this site: Dragonfly - Dunlap Institute

"Dragonfly is an innovative, multi-lens array designed for ultra-low surface brightness astronomy at visible wavelengths. Commissioned in 2013 with only three lenses, the array is growing in size and proving capable of detecting extremely faint, complex structure around galaxies. The most recent upgrade—completed in 2016—saw Dragonfly grow to 48 lenses in two clusters."

Take a look at the last picture on the page!

(If you've been trying to find a Canon 600mm (? not sure what size they are using, but this looks about right), now you know where they've all gone!)

Bigger pixels work out well for astrophotography.

They're Canon 400mm f/2.8 IS II lenses mounted on SBIG STT-8300 monochrome CCD cameras made by Diffraction Limited - Astronomy & Scientific Imaging Solutions .
