Product Overview
Introduction
Push-To Air is a compact wireless Digital Setting Circles (DSC) device designed for Dobsonian and alt-azimuth mounts.
Instead of traditional physical encoders, it utilizes a gyroscope and a magnetometer to measure the telescope’s azimuth and altitude in real time.
Built on an ESP32 platform, it supports Wi-Fi and Bluetooth connectivity, ensuring excellent compatibility with SkySafari for easy star tracking and celestial navigation.
Its lightweight design allows for simple installation and removal, making it adaptable to various telescopes.
Push-To Air eliminates the constraints of wired devices, enhancing the freedom and convenience of stargazing.

Operation
POWER: Turns ON when the power switch is activated and a valid power source is supplied.
CHARGE: ON while charging, OFF when fully charged.
STATUS: ON during normal operation, OFF if an error occurs.
Push-To Air has a built-in rechargeable lithium-ion battery.
Lithium-ion batteries can explode or cause fire if misused or defective.
Please carefully read and follow the safety guidelines below:

- Do not leave Push-To Air in direct sunlight or inside enclosed spaces like a car, where it can overheat quickly.
- Do not drop or apply strong impact to Push-To Air.
How to Use Push-To Air
Powering ON and Preparation
Mounting Push-To Air Horizontally
Attach Push-To Air horizontally in the middle of the telescope using a bubble level.
The closer it is to being level and centered on the rotation axis, the better the accuracy.
However, since it is not a perfect encoder system, approximate leveling where the bubble is near the center is sufficient.
Connection Preparation
- Turn on the switch, and PushToAir_XXXX should appear in available Bluetooth devices or Wi-Fi networks.
- Choose either Bluetooth or Wi-Fi connection.
Bluetooth Connection
- First, register PushToAir_XXXX in the Android Bluetooth settings.
- ℹ️ Bluetooth connection is only supported on Android.
Wi-Fi Connection
- Wireless Network Name (SSID): PushToAir_XXXX
- Password: pushtoair
- ℹ️ After connecting, disable automatic reconnection to the wireless network.
SkySafari Setup Guide
⚠️ Push-To functionality is only available in the paid versions of SkySafari 6 Plus/Pro and 7 Plus/Pro (separate purchase required).
Telescope Preset and Connection
Adding and Configuring a Telescope Preset
- Add or configure the telescope you want to connect to.
- Multiple telescope presets can be added, allowing you to switch between different telescopes.
- To add a preset: SkySafari ⇒ Menu ⇒ Settings ⇒ Telescope (Preset) ⇒ Add New
Connecting to a Telescope
- Select the telescope from the preset list and connect to it.
- To connect: Tap the “Telescope” option in the bottom menu bar on the main screen.
Enabling Telescope Display
- SkySafari ⇒ Bottom Menu ⇒ Observe ⇒ Telescope Display ⇒ Enable Telrad Circles
Recommended Telescope Preset Settings
Set up the following parameters in your telescope preset:
- Mount Type: Alt-Az, Push-To
- Scope Type: Basic Encoder System
- Connection Method:
- Wi-Fi Connection:
- IP Address:
10.0.0.1 - Port Number:
4030
- IP Address:
- Bluetooth Connection: Select PushToAir_XXXX from available devices
- Wi-Fi Connection:
- Time & Location: Off
- RA/Azimuth (RA/Azm): +8192
- Dec/Altitude (Dec/Alt): +8192
- Get Automatically: Off
Connecting to the Telescope
Once a telescope preset is added and selected, you can proceed with the connection.
- Tap the “Telescope” tab in the bottom menu bar to connect.
- If the connection fails, verify Wi-Fi or Bluetooth connectivity.
- If disconnected, reconnect to the Push-To Air Wi-Fi network and retry connecting via SkySafari.
After a successful connection, moving the telescope will update the telescope’s position in SkySafari.
Now, you need to align the telescope by syncing its actual position with SkySafari’s displayed position.
Alignment: “Align” vs. “Restart Alignment”
- Align: Used for initial one-star alignment or for two-star and three-star alignment.
- Restart Alignment: Ignores the previous alignment and starts a new first alignment.
Since Push-To Air is not a high-precision encoder, one-star alignment is recommended over two-star or three-star alignment. Additionally, it is advisable to realign using a one-star alignment near the celestial object you want to locate.
Once alignment is complete, select a target and tap “Push-To”.
SkySafari will display directional arrows to guide the telescope movement toward the target.

Troubleshooting
- Ensure the device is fully charged before use. The CHARGE LED will turn OFF when charging is complete.
- If the connection is unstable or keeps disconnecting, try recharging the battery.
- If the STATUS LED is OFF, initialization has failed. Turn the power OFF and ON again.
- If the STATUS LED is ON but Push-To Air does not appear in the Wi-Fi network list, the battery may be low. Recharge the battery and try again. A low battery can weaken the Wi-Fi signal and cause frequent disconnections.
- Push-To Air can only connect to one device via Bluetooth or Wi-Fi at a time. If you are unable to connect a second device, disconnect the first device before attempting to reconnect.
- The built-in 18650 lithium-ion battery should only be charged between 0°C and 30°C (32°F–86°F).
