Worse, telescope shut down on me (had 20% battery still) when I hit the enhanced vision. Very disappointing. ### 5/5 — Chapeau bas. *2026-07-25* Waouh ! Vous avez changé de développeurs ou quoi ? Cette mise à jour est un énorme bond en avant. Le planétarium est évidemment la nouveauté la plus visible, mais ce qui m’a le plus impressionné, c’est le souci du détail. Le mode Picture in Picture est tout simplement génial, ce sont ces petites attentions qui font la différence. En plus, je n’ai plus aucun problème de connexion avec mon Odyssey Pro. Enfin une application à la hauteur de l’excellent télescope ! Merci à toute l’équipe, et bravo pour ce travail ! ### 5/5 — Super télescope *2026-07-20* Super télescope, l’app pour le piloter fonctionne bien. Le nouveau planetarium est cooool merci!!! ### 5/5 — Quels changements ! *2026-07-17, version 5.0.0* Cette nouvelle version est géniale ! ### 5/5 — La nouvelle maj est exceptionnelle *2026-07-16* L’ancienne version était déjà vraiment cool, mais la nouvelle maj rend l’expérience utilisateur tellement plus fluide et plus riche !! ### 1/5 — Fails to connect too often. *2026-05-02, version 4.2.1* Amazing when it connects. Useless when it doesn’t. Why is it built to be so hard to connect to the telescope? ### 1/5 — 不完全？ *2026-04-07, version 4.2.1* ユーザー登録で登録アドレスへ確認の送信をするために送信ボタンを押すとアプリが落ちてしまいます。 早目の対応をお願いします。 ### 1/5 — Catalogue missing many objects *2026-01-10, version 4.2.1* Why the Seestar has the C/2025 A6 and Unistellar does not?? I have both telescopes but finding myself using(and recommending) the Seestar much more. This is junk, clunky app and connection, lack of features (compared to Seestar) ### 1/5 — Mise à jour Impossible *2025-12-13, version 4.2.1* Impossible de faire la mise à jour 4.2 donc télescope obsolète cet appli rend fou ! ### 3/5 — 知らぬ間に *2025-11-24, version 4.2.0* 木星が綺麗になりました ## Frequently asked questions about Unistellar ### What does the Unistellar App do?
