CCDs with high sensitivity at near 1 micron
An interesting recent development in CCDs is some CCDs that have their maximum sensitivity in the near-infrared.
CCDs used in the Jasmine Space Astrometry mission will have a 90% quantum efficiency at 0.9 micrometers wavelength.
I don't think these are the exotic "infrared only" CCDs with all their attendant problems.
This could enable amateurs to do near-infrared imaging, a useful thing for Milky Way objects which are highly obscured by dust, as the infrared photons have a habit of getting past the dust grains.
