About
MLAstro is the wireless remote control companion for OnStep-based telescope mounts connected through SmartWebServer.
Whether you're in your backyard or at a dark-sky site, MLAstro gives you everything you need right from your phone — no laptop, no cables, no hassle.
KEY FEATURES
● Live Mount Status
See your mount's current state at a glance: tracking mode, guide rates, slew status, and connection health — all updated in real time.
● Full Directional Control
A responsive on-screen directional pad lets you nudge the mount in any direction. Adjust slew rates, start or stop tracking, and send mount utility commands with a tap.
● Home & Park
Safely home or park your mount at the end of a session with dedicated one-tap controls.
● Go-To Catalogs
Browse built-in catalogs and send your mount directly to any object:
- Messier catalog (110 objects)
- Caldwell catalog (109 objects)
- Bright Stars list
- J2000 coordinate entry for any custom target
● Target Detail & Slew
View object details before slewing, confirm the target, and watch your mount move — all from one clean screen.
● Alignment Workflow
Step through the alignment process guided by the app, so your mount points accurately every time.
● Flexible Network Setup
Supports both Access Point and Station (router) Wi-Fi modes. Save your controller's IP address and port so you're always one tap from connecting.
● Configuration & Tuning
Adjust meridian flip settings, slew limits, slew rates, tracking mode, time & location, and controller / axis parameters — all without leaving the app.
● Light & Dark Theme
Choose light, dark, or follow your system preference.
REQUIREMENTS
- An OnStep-based telescope mount controller

MLAstro is built for amateur astronomers who want a clean, capable mobile controller for their OnStep rig. No account required. No cloud. Just your phone and your mount.
