MLAstro Hub

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
• SmartWebServer (or compatible TCP bridge) running on port 9998 (configurable)
• iOS 15 or later
• Same local Wi-Fi network as the mount

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.
