いろいろと残念

画面はきれいだし、青雲や星団の位置まで 載っているので楽しいです。 でも星座のつなぎ方とか星座絵がおかしいこともあるので、正確さに欠けていると思います。 かに座の中にはザリガニではありませんよ。 こと座の星座絵もずいぶんと変な絵ですね。 おとめ座のような12星座は日本で一般的に 使われている形に星をつなげてもいいと思います。わし座もはくちょう座も同様です。 せっかく星雲星団のを載せているのですから M27とからM57のようなメジャーな メシエ天体くらいは表示してほいしものです。 さんかく座の系外銀河は「さんかく座銀河」と表示されていますが、これはM33でいいと思います。メシエナンバーなつくほど有名な天体ですから。
 もしかして開発者さんは日本の天文の本を 読んだことがないのでしょうか？ 星座のつなげ方やあてはめる星座絵が 普通とは違っていたり、 日本では子供向けの天文の本にも 載っている天体を知らないのは 外国の知識のせいかもしれません。 せっかくきれいな星空を映し出せる のですから、もう少しお勉強して ほしかったです。 あちこちに違和感を感じるので 使うには不安を感じるアプリです。
