What happen to mercury when the sun dolor got hit last year

Magnifique application ma préféré

Après avoir chargé et déchargé presque toutes les applications dans le but de voyager ou repérer les étoiles galaxies, j’ai enfin trouvé! où l’on peut aller presque partout dans son coffins en cochant les étoiles proche de la galaxie lointaine recherché par exemple. On à vraiment l’impression de voyager à la vitesse de la lumière. Merci j’adore. Seb

Too many; too disruptive.
Sad, because I was an “early adopter” of Redshift decades ago, pre-APPs, and loved it.

Wishes: red light option and others

I wish there was an option to show things in red to preserve night vision.

Also, the "pointer" takes up a fair amount of screen real estate (blocking other things) plus it's big.

I wish it was a just a thin circle with some centering marks (but not blocking the middle sight.). Maybe a bit like a magnifying glass.
