I would say that the correct separation is 0.3 arcsecs and that is why you can't split the pair.

It is likely the error is by the WDS crew. Not sure how that could happen as the separation has been measured at least twice.

SkySafari is just reading their error.

Hi Rob.

Gee whizz, if it's 0.3" separation then it is really a tough split! I have an incoming 14 inch dob, but 0.3" is right at its limit. Sargas may need at least a 20 inch with super steady seeing to resolve. Thanks for your input

Clear Skies
