Today I stumbled upon the first photograph of the Orion Nebula, taken by Henry Draper in 1880. I realized that it looked a lot like an image I was able to get through my telescope in December, 2013 using my iPhone!
I’ve compared the two photos below.
In about a second – with equipment we can carry in our pockets – we’re now able to outdo what used to take almost an hour. Now that’s progress!
