This app focuses on answering a beginner's most common question: "What will I actually see with this equipment?" It simulates the view formed by your telescope with your chosen eyepieces, and supports custom telescopes, eyepieces, Barlows, and cameras. It includes built-in hardware databases (William Optics, Meade, Celestron) and a library of celestial objects including the Sun, planets, and all NGC and Messier objects. The app also provides a warning if a combination exceeds the maximum useful magnification of your telescope.

: An incorrect combination of telescope and eyepiece can make a massive deep-sky object like the Orion Nebula appear cut off, or a tiny planet look like a microscopic speck. Sensor Crop and Vignetting Whether you choose the
