Software Guide of EZ PUSH TO 2019 on iOS 2019.5.15 Ver1.0

1. Devices should be iPhone 6S+ or later models
2. Search “EZ PUSH TO” and Install the app from Apple Store
3. Turn ON “Bluetooth” in iPhone settings. Do not pair the Bluetooth device named “Romer Optics”. You must connect the BT via our App
4. Power On the EZ PUSH TO Kit installed on your Dobsonian
5. Run the app “EZ PUSH TO”

Connect Pair

1. Please wait seconds to load star database

2. Click “BlueTooth OFF”, connect “Romer Optics” in the devices list Activate “GPS ON” to confirm UTC / Longitude / Latitude UTC = Time Zone + DST (daylight saving time).

3. *“Load Encoders Offset dialog” does not show up in the first time. “Ignore” encoder offset to start new stargazing. or “Load” to restore previous encoders alignments data. ” Load” causes faulty az/alt output even if your Dob’s base was slightly moved.**

4. *Set the ALT encoder installed at LEFT/RIGHT(default) hand side wrong side makes the altitude encoder read out reversely.**

5. Pre-Offset Encoders Find and Locate Polaris in your Dobs’s eyepiece Click “POLARIS” to complete it

   • offset encoders could be faulty without a calibrated compass in the handset.
   • avoid Compass Offset except that stars are invisible at daytime
     After Pre-Offset Encoders, check and confirm az/alt is displayed correctly.

6. Settings on the left top of Menu / Click “Cancel” to leave it

   • ”High Frame rate” probably causes the handset to show fewer stars and narrower FOV on the slower or outdated handsets.
   • ”NGC ON”: All NGC objects only appear in the Starry Roaming when FOV is less than 12 degrees.

7. Roaming
   Push Dobsonian to browse popular objects ( for example Mars) app helps to select the closest target. Click the top “Green Label” to push to

   • popular objects: 110 Messier / Herschel 400 List / NGC (enable it in settings) /double and binary star/asteroids (enable it in the solar system)

8. Deep Sky Outlook

   • Click “number” to set Messier or NGC object
   • LONG PRESS “Messier” or “NGC” to push to the target
   • Input self-defined RA/DEC / Select a star in 88 Brightest Star Table

9. Solar System

   • Click the picture to select planet / coming comets / Asteroids
   • Asteroid includes more than 700 brighter objects which could be visible. You may select one or “Asteroid Roaming” to browse them at the same time.

10. Push To

    • Arrows on the sky map ( up/down/left/right) and a blink Circle guides your Dob to the selected target. ”Encoder Offset” is used to improve system accuracy when the selected target is not displayed consistently.
    • Locate the target in your eyepiece, and click “Encoder Offset” to complete the calibration. The more calibration you did, the more accurate your Dob could be. You can reset encoders offset in settings when you did the wrong calibration.

11. Messier Marathon
    Train yourself to search Messier Object for fun Push you Dob to search Messier objects. The app helps you to record whether you find the object successfully or not. Click “Messier Check” when ready. Update your record if the objects are found.

12. Multi-Star Alignment
    Polaris / One-star alignment provides acceptable accuracy for quick stargazing. The more stars are selected to calibrate the system, the more accurate your Dobsonian could be.

    • Please level your Dob as perfectly as possible by 3 bubble level meters.
    • Push Dob to browse targets. Click “Green Label (Encoder Offset)” at the bottom to select the aligned target.
    • Locate the selected aligned target in your eyepiece.
    • Click “Green Label” again to offset the encoder when ready.
    • Choose another target for the next calibration.
    • At least 3-star alignments are required. The spacing between selected aligned stars must be as wide as possible (for example az = 0 / 120 / 240 degree, alt is about 45 degree)
    • At most 12 stars (12 zones, one star every 30 degrees) are applied for alignments.

13. PEC
    Periodic Error Correction is easily explained in a text document. Please watch the clips on Youtube.
