Apr 20 at 15:18 comment added user1621287 Like, maybe where I could find two images with and without gravitational lensing, presumably brightness/illumination normalized that are combined with color differencing? Surely, SOMEONE has done that.

Apr 16 at 2:02 comment added user1621287 My goof - "in which the Sun is blotted out using an opaque circular area held between the camera and the sun" makes no sense, certainly not without collimation. Can't one make out the stars during the day from the bottom of a well, though such a well wouldn't necessarily point at the portion of sky of interest. But suppose it's six months later, as Peter suggests. Surely someone has compared the portion of the starfield of interest with color differencing. I'd like to see an example.
Apr 14 at 17:19 comment added Peter Erwin What would make more sense would be to compare your photograph of the stars near the Sun during the eclipse with a photograph of the same field of stars ~ six months later, when it's night. Of course, to demonstrate GR, you'd have to actually measure the deflection of stars near the Sun (during the eclipse), since there was a non-GR prediction that had half the effect.
Apr 14 at 17:16 comment added Peter Erwin @user1621287 Use your hand to blot out the Sun. Can you see any stars?
Apr 13 at 13:48 comment added user1621287 Might need a collimator too?

Apr 12 at 19:20 comment added ProfRob "which the Sun is blotted out using an opaque circular area held between the camera and the sun, " this doesn't work.
