Page 3: Introduction
Within its load capacity, the rotator ensures absolute zero flex at any angle, eliminating concerns about changes to the focal plane. The Wanderer Rotator V2 series is available in three models: Mini V2, Lite V2, and Pro V2, corresponding to M54, M68, and M92 thread sizes, respectively. - Page 4 WandererAstro Figure 1 The specifications of WandererRotator Mini V2 are shown in the table below.

WandererAstro Figure 6 Dimension of WandererRotator Lite V2 Note that in the side view of Figure 6, the thickness of the rotator is 13.65mm, it includes the raised back cover portion (Figure 7). The actual thickness occupied by the rotator is 12mm. - Page 8 WandererAstro 16mm). Additionally, it offers extremely high positional accuracy, with 1349 steps per degree (0.0007 degrees/step), enabling an effective resolution of 0.005 degrees, making precise field de-rotation possible. Compared to the previous version, the Wanderer Rotator Pro V2 features a family-style design for enhanced recognizability (Figures 8 and 9).

Page 10: Installation And Use
WandererAstro 2.Installation and use Connect the rotator to the PC using the included USB data cable and supply 12V power. The rotator connects to the telescope via threading, with the protruding side typically facing the telescope (Figure 12). Figure 12 The WandererRotator Mini V2 comes standard with dual-sided M54 female threads. -
Page 11: Driver Installation
WandererAstro includes a standard M92 male thread adapter, which can be secured to either side of the rotator using screws. Important Note: WandererRotator Mini V2: Due to its ultra-thin design, the depth of the M54 female threads on both sides is only 5mm. When connecting M54 male thread adapters to the rotator, ensure that the thread length is less than or equal to 5mm (4mm is recommended). -
Page 12: Connecting The Rotator (Using N.i.n.a. As An Example)
WandererAstro 2.2 Connecting the Rotator (Using N.I.N.A. as an Example) After installing WandererEmpire, double-click to open the software. In the left-side menu, locate and select the "WandererRotator" option (Figure 6). Figure6 At the top of the interface, you will see options labeled "Device 1," "Device 2,"... - Page 13 WandererAstro correct COM port, it is recommended to enable "Select COM Manually" and select the identified COM port to speed up future connections. Figure7 Next, locate the corresponding ASCOM device driver in N.I.N.A. If you connected the rotator under the "Device 1" option in WandererEmpire, select WandererEmpire Device 1 in N.I.N.A.

Page 14: Configure Phd2
WandererAstro 2.3 Phd2 Configuration If using the OAG, the rotation will also cause the angle of the guide camera to change, invalidating the guiding calibration data. In this case, you need to connect the rotator in PHD2 so that PHD2 can adjust the guiding calibration data based on the rotator's angle, avoiding the need for recalibration. -
Page 15: Set Backlash
WandererAstro If guiding does not work correctly after rotation, try enabling the Reverse sign of angle option under the "Other Devices" section in Advanced Settings (Figure 11). Figure11 2.4 Set the Backlash The default backlash setting is 0.5°, which usually does not require adjustment. -
Page 16: Set Reverse
WandererAstro 2.5 Set Reverse If the rotator fails to rotate to the specified angle after multiple attempts during plate solve and there is a large deviation, it means that you need to check the reverse. Whether to check the reverse depends on your imaging software and optical system. -
Page 17: Firmware Upgrade
WandererAstro 3.Firmware Upgrade The firmware upgrade feature has been integrated into WandererEmire. Click on the left-side menu to access the firmware upgrade interface (Figure 12). We recommend carefully reading the firmware upload tutorial on the right side of the interface. - Page 18 WandererAstro Below, select the correct COM port (if unsure, refer to Chapter 2.2 to automatically search for and note the COM port) and the correct Option (Figure 14). For V2 rotators, select Option 1; for V1 rotators, most require Option 1, though a few may need Option 2. After completing the settings, click "Upload."...

Page 19: Rotation
WandererAstro 4. Field De-Rotation The WandererRotator series support field de-rotation for users of Alt-Azimuth mounts, which can play a significant role in planetary photography and enable longer exposure times in deep-sky imaging. Thanks to its ultra-high rotation precision of 0.0008 degrees per step, the de-rotation results of the WandererRotator is outstanding. -
Page 20: Get The Ra/Dec Of The Target
WandererAstro 4.2 Get the RA/DEC of the target WandererEmpire also requires the Right Ascension (RA) and Declination (DEC) coordinates of your target to complete field de-rotation. There are three methods to obtain these coordinates: 1. Manually input the coordinates (Figure 17). - Page 21 WandererAstro Figure19 Figure20 3. Extract coordinates from saved FITS files. Figure21 FITS files captured by your cooled camera contain the center coordinates of the images. WandererEmpire can read these coordinates. Click "Select...

Page 22: Start Field De-Rotation
WandererAstro Folder" to choose the folder containing your saved images (or parent folder). Then, click "Sync," and WandererEmpire will automatically sync the coordinate information from the latest FITS files in the selected folder and its subfolders (Figure 21). 4.3 Start Field De-Rotation Once everything is ready, click "Start De-Rotation"... - Page 23 WandererAstro Figure22 WandererRotator offers 3 key actions in Device Actions: Start De-Rotation, Stop De-Rotation, and Sync Coordinates to WandererEmpire. By using these actions correctly, you can automate the entire imaging workflow. Parameters of the Actions are all not required. A typical sequence template is shown in Figure 23: 1.
- Page 24 WandererAstro Please note that NINA can only load the Action after the device is connected. Therefore, you need to connect the ASCOM driver first and load the sequence to see the Actions, or you will only see blank Action (Figure 24).

Page 25: Faqs
WandererAstro 5.FAQs Q: What is the rotation precision of the Wanderer Rotator Mini? A: The Wanderer Rotator Mini features an ultra-high resolution of 0.0008 degrees per step. Based on multiple tests and user feedback, if backlash settings are properly configured (generally leaving the default settings), the rotator can achieve a precision of better than 0.02 degrees after two iterations... - Page 26 WandererAstro Q: Why does the rotator keep rotating and cannot reach the specified angle during Plate Solve? A: This means you are using the wrong Reverse setting. Note 1: Calculations are based on a load balance distance of 10 cm from the...
