Fwd: KStars gravitational lensing

[Jasem Mutlaq]

Hello everyone,

I'm forwarding an email I received from Dr. Lorenzo regarding
the "Gravitational lensing effects around the Sun" feature in KStars. I
actually never used this at all, anyone has any ideas?

Dear Jasem,

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

Thank you for your time and assistance.

Best,

Lorenzo
