User Reviews

OnStep Controller2 is praised for its rich features, easy setup, and stable integration with telescope hardware, especially replacing older hand controllers and enhancing user experience. Users appreciate its open-source nature and continuous development. However, multiple users report frequent app unresponsiveness and freezes, impacting usability. A few features such as accurate UTC offset handling, PEC index indicator, and enhanced focus controls are missing or need improvements.

Pros

Easy setup and connection.
Rich features making it a complete and easy to use telescope control app.
Effective replacement for traditional hand controllers and other control methods, especially with Bluetooth integration.
Stable operation with OnStepX and useful for observations without a PC.
Open-source project with strong community appreciation and continuous improvements.

Cons

App frequently becomes unresponsive or freezes, causing pop-up errors every few seconds.
UTC offset settings are inaccurate, requiring a manual hour adjustment.
Missing some features like PEC index indicator and polar hour angle calculator for better debugging and alignment.
Lack of certain controls like a slide bar for focus adjustment instead of just buttons.

Nice app, much better than an old Hand Controller. Tons of features, OnStep is very complete and easy to use. Only missing feature: a PEC index indicator (useful for debugging the system...).
