At only 1080p on a full 35mm sensor it would want to capture some light with the size of the light buckets lol. Its great news though i can only see it being used in a very expensive hd cam, which still would rock hard for planetary work for sure and even video astronomy
Only bad thing is i could not see cannon building an astro dslr with the sensor because it would not make them any money, though maybe an outside group could pick it up for an imager
Lol If they come up at a far enough price i'am going video obs for sure.
