(測試) 天文望遠鏡觀星模擬器Telescope Stargazing Simulator

天文望遠鏡觀星模擬器Telescope Stargazing Simulator

時間與地點Time & Location
（東經、北緯為正）(E, N positive)
點擊地圖設定觀測地點（時區依經度估算，可再手動調整）。時區未含日光節約時間。Click the map to set the site (time zone estimated from longitude; adjust if needed). Daylight saving time is not applied.
拖曳平移（在東西南北視角拖曳會自動切換為「自訂」，可任意調整方位與仰角）、滾輪或雙指縮放；點擊天體或天空即讓望遠鏡指向該處。Drag to pan (dragging in N/E/S/W switches to Custom so you can aim at any azimuth/altitude); wheel or pinch to zoom; click an object or the sky to point the telescope there.

說明：望遠鏡視野中的月球與行星是以真實探測器影像製成的表面圖（NASA LRO、Cassini 等）即時貼附於球體，依日期計算相位、自轉軸方向與土星環傾角；深空天體為真實天文攝影照片，依天空座標定位疊加。影像由 cdn.jsdelivr.net 即時載入（Stellarium 開源影像集），若無法連線則暫以示意圖代替。Note: the Moon and planets in the eyepiece are rendered from real spacecraft-derived surface maps (NASA LRO, Cassini, etc.) wrapped on a sphere with the computed phase, pole orientation and Saturn ring tilt; deep-sky objects use real astrophotographs placed by sky coordinates. Images load from cdn.jsdelivr.net (Stellarium open image set); if unreachable, a schematic is shown instead.
說明：星表內建 5.5 等以內的亮星；望遠鏡視野中更暗的背景恆星為依銀緯密度模型程序化產生的示意星點，位置並非真實星表。Note: the built-in catalog holds stars to mag 5.5; fainter background stars in the eyepiece are procedurally generated from a galactic-latitude density model and are illustrative, not real catalog positions.
