<br>
I am Lorenzo, a post-doc in astrophysics at University of Ferrara, <br>
Italy. I'm preparing a lecture for high school students on gravitational <br>
lensing, and I just found out KStars. In particular, the website <br>
mentions: "Switch on and switch off gravitational lensing effects around <br>
the sun to understand Eddington’s experiment". I am trying to visualise <br>
the deflection of starlight caused by the Sun on May 29, 1919, from <br>
Principe Island (i.e., Eddington’s experiment), however, I am unable to <br>
observe the expected deflection of nearby stars. Could you please <br>
clarify if this feature is functioning as intended, or if there are <br>
specific settings I need to adjust? I've already downloaded some extra <br>
stars catalogues. Do you confirm that I just have to press the "R" key <br>
to activate the lensing effects?<br>
<br>
Thank you for your time and assistance.<br>
<br>
Best,<br>
<br>
Lorenzo<br>
