Weirdness in stellar parallax

[Atque]

When exaggerating the parallax to 10k or 20k, we see that Procyon errenously has a visually larger parallactic ellipse than the closer Sirius. We see the same problem with Pollux and Castor, with the latter being almost stationary. See the video snap below for Procyon/Sirius.

Procyon clearly "looks" more nearby than the IRL closer Sirius.

Sirius and Castor are multiple stars. Perhaps the parallax is incorrectly displayed? Note that the infostring gives reasonable values, only the drawing seems flawed.

I agree Procyon seemingly has a larger parallax than Sirius.

FYI I will be on vacation until the end of September. So it will take a while before I take a deeper look.

Hello @Atque!

OK, developers can reproduce the issue. Thanks for the report!
