およそ５等星以上の恒星データや星座線，惑星の軌道要素などを使ってある年月日，時刻の星空を再現するプログラムをPythonで作ってみました。星座だけでなく，惑星，月，太陽の位置もわかる，一応プラネタリウムソフトでもあります。はじめは中野主一さんの「マイコンで解く天体の謎」（1982年）を参考にして作ったのですが，惑星や月の位置計算が500年もするとずれてくることに気づき，斉藤国治さんの「古天文学」（1989年）の計算方法を移植しています。これで紀元前の日食なども再現できるようにしました。ソースコードが1000行以上にもなってしまいました。ソースコードにご興味がある方は，参考にしてみてください。（2020年3月にバージョン2で実行ファイルをつくりました。）。恒星データは https://heasarc.gsfc.nasa.gov/W3Browse/star-catalog/hipparcos.html ，星座線や星座名のデータはAstro Commons (アストロ・コモンズ)。 http://astronomy.webcrow.jp/help/ から得ました。
現在バージョン3.0.1で（下のpaythonソースコード）画面サイズは1100×750（px）のノートパソコンでも示せるサイズ（残念ながら大きさを自由に変えられる方法を知らない）です。（2023年1月）
ダウンロードページにあるデータファイル「seizaData」をダウンロードして，同一ディレクトリに置いて 実行すると，ステレオ投影図法の天球に恒星と星座線，星座名および月惑星（太陽も）が表示されます。右上のinputボックスに見たい年月日や時刻を例にならって入力し（例；YYYYMMDD＝20201028→2020年10月28日）Enterキーを押してください。 初期状態で表示されるのは，2035年9月2日の日本の北関東で起こる皆既日食になっています。 昼間も夜空のように星が見える天体シミュレーターとしてつくられています。
2020年3月に，実行形式のファイル（画面サイズが小さい1100×750) を作りました。Python3がインストールされていなくても，お試しいただけます。こちらからダウンロードしてください。 → 星座早見プログラムダウンロード
