Quote:Thank you, Randy. I was about to confine myself to the looney bin. So now it's what, down by seven or eight, going into the fourth quarter?
Yes, any separation estimate would be helpful. Even proximity to a diffraction ring.
Fred, as soon as you hear from Mason; do tell!

if advertised data and observations of Bill is to be confirmed then you should get a nice diamond ring with the companion sitting on the first ring. If John reported correct then it would be an easy resolution in the second minimum. Can it be this easy?
If David's report reflects reality you will get a negative result but to confirm it you will need another scope.

Quote:Note the details I and others gave in discussing the pair in the earlier thread. The separation is now pretty definitely LESS than 1.0".
