Ice Fishing

Every telescope 🔭 hides a set of numbers 🔢, and the numbers decide the night 🌙. Ice Fishing 🐟 is a worksheet 📋 for them: pick a telescope 🔭, pick an eyepiece 👁️, and the magnification 🔍, true field of view 🌌 and exit pupil ⚪ settle on screen 📱 in clean instrument digits. Add a Barlow ➕ or a reducer ➖ and every figure recomputes at once ⚡, with a full table 📊 of all your eyepiece combinations ranked below ⬇️ - and a quiet warning ⚠️ when a pairing pushes past what the aperture can honestly deliver. Ice Fishing keeps every calculation precise and instant.

The field-of-view ring ⭕ answers the question every stargazer ✨ asks: will it fit? Choose the Moon 🌕, Jupiter 🪐, the Orion Nebula 🌌 or any of the bundled deep-sky targets 🌠 and see it drawn to scale 📏 inside your eyepiece circle - how much of the frame it fills 🖼️, which of your eyepieces gives it room to breathe 🌬️, and which crops it ✂️. Star ⭐ the targets you want for later; they wait in their own saved list 📌.

Your equipment 🧰 lives in a proper kit inventory 📦. Each scope 🔭, eyepiece 👁️ and accessory 🔩 carries its computed spec sheet 📄 - focal ratio 🔢, resolving limits 📏, useful magnification range 🔍 - and a photo 📸 you take of the actual instrument, replaceable 🔄 or removable ❌ whenever you like. After a night out 🌌, record the session 📝: date 📅, instrument 🔭, sky conditions 🌫️, the targets you found 🎯. A heat calendar 🔥 collects your observing nights 🌙, and the season page 📊 reads the record back as charts 📈 - nights out 🌃, most-observed objects 🌠, and the magnification sweet spots 🎯 of your own kit.

Everything computes on the device 📱, with no connection 🌐❌ required at the eyepiece 👁️. The observer name 👤 is yours to set ✏️, change 🔄 or clear ❌, and every photo 📸 and log entry 📝 can be edited ✏️ or deleted 🗑️ at any time ⏱️. Ice Fishing keeps your observations private and fully under your control.
