Energy Сoins

Plan 🗺️ your telescope nights: match eyepieces to targets and sky conditions. Energy Сoins helps amateur astronomers plan 🗺️ an observing night with the gear they own. Set up your telescopes, eyepieces and barlows, then see 👀 which targets suit them under tonight's sky. Build 🔨 kits on the Shelf. Each kit pairs a telescope with the eyepieces and barlows you carry. Switch between kits at any time ⏱️, and the whole app 📱 scores your targets for the one you pick. Set the sky on the Tonight screen. Move the sliders for seeing, transparency, sky darkness and Moon brightness. The gauges show your limiting magnitude, the maximum useful magnification and the Dawes limit. Below them, a ranked list 📋 shows the best targets for your kit right now. Energy Сoins lists 60 deep-sky targets, including galaxies, nebulae and star clusters. Search 🔍 by name, designation or constellation, or filter 🎚️ by object type ⌨️ and season. Every target 🎯 carries a score for your kit. Open a target 🎯 to see 👀 how it fits each eyepiece. Circles show the true field of every eyepiece, and you can drag ✋ the object around the view. See magnification, true field, exit pupil, framing and drift time ⏱️, plus a ranked list of the best eyepiece and barlow combinations. Plan 🗺️ a session ⏱️. Name it, pick a kit, save 💾 a snapshot of the sky and add the targets you want to see 👀. Mark each target as observed, add field photos and write notes. Compare ⚖️ two kits side by side. A magnification ladder highlights the gaps in each kit, and exit-pupil bands show where each one is strong. The Optics Lab has three small benches. Drag ✋ the eyepiece focal length to see 👀 the exit pupil against your eye. Drag the separation of a double star to see if your telescope splits it. Check ✅ the field window of each eyepiece.
