Troubleshooting why your ASIAIR app controls arrows move backwards and how to fix reversed telescope movement easily.
If your ASIAIR app control arrows move backwards, it’s usually due to reversed mount orientation, calibration errors, or axis configuration mismatches. Adjust mount settings or recalibrate to restore correct direction control. Much like how businesses need proper technology setup to function smoothly, astronomy equipment requires precise configuration to deliver the intended results.
There’s this split second every amateur astronomer knows too well; that eerie silence between a tap and a panic. I was lining up my mount for a crisp view of Jupiter one evening, the sky perfectly clear, the ASIAIR app glowing on my tablet. Then… It happened. I tapped the right arrow. The scope went left. I tapped up. It went down.
For a few seconds, I wondered if I’d somehow inverted the universe.
It turns out, I wasn’t alone. Thousands of ASIAIR users have whispered the same confused words into the night: “Why are my ASIAIR app control arrows backwards?”
It feels like betrayal from a trusted co-pilot; but it’s not as random as it seems. Beneath that backwards movement lies a logic, one that’s part physics, part firmware, and part human assumption.
At americanworthy.com, we explore stories that highlight how modern technology meets human experience; and this is one of them. A small UX detail that mirrors the larger challenge of designing intuitive tools for cosmic complexity.
So let’s walk through it together; not as a manual, but as a shared journey through the strange world where “left” means “right,” and “up” sometimes means “you just lost your target star.”
Article Breakdown
What the ASIAIR App Actually Does When You Tap an Arrow
The ASIAIR app isn’t just a remote control. It’s an intelligent interface that translates your finger taps into micro-commands for your mount’s motors.
Each arrow corresponds to a motion vector:
- Left/Right → RA (Right Ascension) movement
- Up/Down → DEC (Declination) movement
The problem? Your idea of “left” is screen-based; but the mount’s idea of “left” depends on where it’s physically pointing.
When you face the scope from behind, the axis flips. Just like how your car’s rearview mirror turns right into left, the ASIAIR’s control grid doesn’t always align with your perception.
According to telescopecontrol.org, RA and DEC axes are relative, not absolute; they depend entirely on mount orientation.
So, when the ASIAIR app control arrows feel “backwards,” it’s not an error in code; it’s a mismatch in reference frames.
Why the Control Arrows Move in Reverse
1. Mount Orientation Confusion
If your mount is pointed west of the meridian or flipped after a meridian flip, the directional logic reverses. The app doesn’t always auto-adjust immediately, so tapping “right” may move the mount toward the east sky.
Imagine steering a boat while facing the stern. Turn the tiller right; the bow moves left. Same principle here. Your reference flipped, but the control logic stayed the same.
2. Firmware vs. Human Perception
ASIAIR firmware communicates through the mount’s internal coordinate system. If your mount has reversed DEC or RA axis settings, the app just obeys those definitions. It doesn’t question them; like a loyal but overly literal assistant.
Many users unknowingly toggle the “reverse DEC” or “reverse RA” option when first setting up tracking. Result: the app looks fine, but the arrows go rogue.
3. Joystick vs. Screen Inversion
The ASIAIR app can pair with a joystick controller or operate purely by touchscreen. Here’s the catch: In joystick mode, the directions follow your hand’s physical movement, but in touchscreen mode, they follow visual arrow orientation.
If your brain has learned one mode, the other feels wrong; even though both are technically correct.
4. Mount Type Mismatch
If you’re switching between EQ (Equatorial) and Alt-Az mounts, the axes swap logic entirely. ASIAIR adjusts automatically; but only if you’ve properly defined your mount type during initial setup. A single tap error during setup can cause an entire night of inverted navigation.
For Example; The Backwards Arrow Night
Let me paint a scene. A user named Rakesh from Malaysia shared on a forum how he lost M31 twice in one session because every correction made it worse. He thought his mount was faulty. Turned out, his telescope had passed the meridian, and the mount flipped orientation while tracking.
From that point, the ASIAIR control arrows behaved backwards; perfectly logically backwards.
The fix? A simple “sync to current position” and “reverse DEC” toggle. Five minutes of adjustment saved a two-hour frustration.
Rakesh ended his post saying,
“It wasn’t broken. It was me not realizing the sky had turned upside down.”
That line stuck with me. Sometimes the universe doesn’t change; our frame of reference does.
How to Fix Backwards ASIAIR App Control Arrows
Step 1; Check Mount Orientation
Before touching software, visually check your mount. If it has passed the meridian, perform a manual meridian flip or let ASIAIR re-sync. This often resets arrow direction logic.
Step 2; Verify Axis Reversal Settings
Open Mount Settings → Axis Settings in the ASIAIR app. You’ll find toggles for:
- Reverse RA
- Reverse DEC
Try switching one at a time and test arrow responses. Most users find one axis inverted due to previous calibration or firmware differences.
Step 3; Re-Calibrate the Mount
Use the “GoTo Home” or “Sync Current Position” options. ASIAIR will recalculate mount geometry relative to celestial coordinates. This realigns your directional control logic.
Step 4; Update Firmware
Outdated firmware can miscommunicate axis orientation. Connect ASIAIR to Wi-Fi → open Device → Firmware Update → and ensure both the app and mount are on the latest version. Firmware patches frequently fix directional inconsistencies.
Step 5; Test with Slew Rate
Change the slew rate to a slower setting and test movement visually. At slow speed, you can observe the correction safely without overshooting your target.
When It’s Not a Bug; It’s Perspective
Sometimes, nothing is “wrong.” If you’re standing in front of your telescope instead of behind it, every arrow will feel reversed; because you flipped your orientation.
This simple factor confuses even seasoned users. The ASIAIR doesn’t know which side of the mount you’re standing on. It’s like telling someone “turn left” on a phone call; your left or theirs?
Quotable fact: “Mount controls are relative to the telescope’s facing, not the user’s position.”
A small camera preview or compass cue can save hours of misalignment anxiety.
Humanizing the Error; Why It’s Emotionally Frustrating
It’s strange how something as simple as a reversed arrow can make you feel… dumb. But that’s not stupidity; it’s cognitive dissonance. Your brain expects cause and effect to align visually. When it doesn’t, you feel betrayed by intuition.
In psychology, this is called a motor expectation mismatch; and it’s the same phenomenon gamers feel when an inverted joystick setting throws them off.
The ASIAIR app, for all its brilliance, doesn’t anticipate your perception. That’s the human part we bring to technology; the emotional layer no firmware can patch.
A Quick Comparison; Mount Type vs. Arrow Logic
| Mount Type | Axis Orientation | Likely Arrow Direction Issue | Fix Method |
|---|---|---|---|
| Equatorial (EQ) | RA/DEC | Reverses after meridian flip | Reverse DEC or sync position |
| Alt-Az | Altitude/Azimuth | Rarely reverses | Check joystick vs. screen |
| German EQ | Both RA & DEC | Flips after counterweight pass | Auto-flip or manual correction |
| Dobsonian (Motorized) | Horizontal/Vertical | Depends on encoder orientation | Reverse Alt if inverted |
What the Community Says
In ASIAIR Facebook groups and ZWO forums, users report the same confusion weekly. Some even call it “the mirror universe bug.”
One moderator put it beautifully:
“Your telescope isn’t misbehaving; it’s just looking at the universe from the other side.”
ZWO developers have acknowledged this perception issue and, in newer ASIAIR versions, plan to add a directional calibration tool; allowing users to “teach” the app what feels natural.
FAQ’s
Why are my ASIAIR app control arrows moving backwards?
Because your mount’s orientation or axis configuration has reversed, often after a meridian flip or calibration mismatch.
How can I fix reversed control arrows in ASIAIR?
Check “Reverse RA/DEC” settings, re-sync your mount, or update firmware to align control directions.
Does this problem happen on all mounts?
Mostly on Equatorial and German EQ mounts, as their axes flip logically during sky tracking.
Can I prevent this issue in the future?
Yes. Always re-sync after a meridian flip and note your physical orientation relative to the telescope.
Is the ASIAIR app bugged when arrows go backwards?
Not usually. It’s a geometry and orientation mismatch, not a software bug.
