In terms of light-gathering power, how does the LBT compare to the Hale Telescope?
Answer
It gathers more than five times the light of the Hale Telescope.
The Hale Telescope had a light-collecting area of roughly 20 square meters, whereas the LBT's effective aperture translates to over 111 square meters, allowing it to gather more than five times the light in the same exposure time.
