Stellarium 26.1 is the most popular application for the beauty of the night sky like VR on your eyes, so this can also make your screen into a real interactive planetarium. If you are a beginner or a pro to this, this latest release makes the universe easier, smoother, and more attractive.

Stellarium 26.1 is intended to simulate what one would see through an eyepiece. This configuration dialog can be used to add, modify, or delete eyepieces and telescopes, as well as CCD sensors. Your first time running the app will populate some samples to get you started.

You can choose to scale the image you see on the screen. This is intended to show you a better comparison of what one eyepiece/telescope combination will be like when compared to another. The same eyepiece, two different telescopes of differing focal length, will produce two different exit pupils, changing the view somewhat. The trade-off of this is that you have a need for it.

You can toggle a crosshair in the view. You can toggle a TALF finder. This feature draws three concentric circles of 0.5*, 2.0*, and 4.0*, helping you see what you would expect to see with the naked eye through the telrad(or similar) finder. You can adjust the diameters or even add a fourth circle if you have a different finder, or revert to the standard Talrad sizes.
