How the Star Adventurer Works for Astrophotography

Due to the rotation of the Earth, stars are not stationary. They appear to circle around the celestial poles of the Earth (Fig1). Thus, being very faint and constantly moving across the sky, stars are impossible to be captured on photographs, unless the camera is able to track them steadily to allow long exposure. Star Adventurer provides the solution. With the high precision motor and built-in polar scope, Star Adventurer can be set to compensate exactly for the star movement by rotating the camera in the direction opposite to that of the Earth (Fig 2). The result is, the celestial objects appearing in the field of view of your camera do not move anymore and so, taking a picture with a long exposure time is possible while star trails (Fig 1) are eliminated. Fig. 3 illustrates how rich and sharp your night sky pictures can be with Star Adventurer. In addition, Star Adventurer is also capable of tracking at solar and lunar speeds.

Mode Dial

Mode Dial: For power control and selection of pre-programmed modes.
S-TIMELAPSE-N Slide Switch: for selection of rotation direction and camera shutter interval.
Buttons: The right, left buttons are used for rotating in higher speed (about12X celestial tracking speed).
LEDs: The LEDs built-in buttons provide the lighting source in the dark night and indicate the device status such as low battery and motor error.
Snap: This is a 2.5mm 3-segment stereo jack for connecting to a camera's shutter control port to control camera shutter interval.
After finishing the preparation steps, you can start to enjoy the Star Adventurer. The description of the major functions is as following:
Main Function: Star Adventurer has a user-friendly Mode Dial and S-TIMELAPSE-N Slide Switch to allow users easy selection of the pre-programmed movement pattern. At the other side of the Star Adventurer, the two buttons give direct access to higher speed movement for quick positioning.

Mode Dial: lt is used to turn on/off power and select the desired modes shown in table 1. When the Mode Index is pointing at OFF, the mount has no power. If rotated to other modes besides OFF mode, the power is turned on. The LED on the Mode Dial will light up to indicate the current mode, and the LED on the buttons will light up, too. Meanwhile, Star Adventurer will start tracking at the constant speed corresponding to the mode selected (Please refer to the table 1).

3-Positions Slide Switch

3-Postions Slide Switch: Selects the rotation direction of the Star Adventurer and the camera shutter interval. When the switch is slid to N or TIMELAPSE, the Star Adventurer will rotate in the direction of tracking celestial objects in northern hemisphere which is counter-clockwise when you look at Polaris; When the switch is slid to S the Star Adventurer will rotate in the direction of tracking celestial objects in southern hemisphere which is clockwise when you look at the celestial pole.

Right/Left Buttons

Right/Left Buttons: They are used to rotate the Star Adventurer at higher speed for easier positioning on the desired object. While Right Button is pushed, the Star Adventurer will rotate in the speed of 12 times sidereal rate and in the same direction as when we slide the switch to N or TIMELAPSE; While Left Button is pushed, the Star Adventurer will rotate in the speed of 12 times sidereal rate and in the same direction as when we slide switch to S.

Camera Shutter Interval Control

SNAP (DSLR Shutter Control Port): Star Adventurer provides a camera shutter control interface to control the shutter interval. The SNAP port is a 2.5 mm 3-segment stereo jack and the trigger signal connects to the tip and base segments. With the proper Shutter Control Cable connecting your camera and Star Adventure, the mount can control the camera's shutter release (please refer to DSLR Shutter Control Cable in the Optional Accessories). The Shutter interval period of every selected mode has been pre-programmed. Please refer to the Table 1. For example, when the Mode Dial is set to Mode and Slide Switch is set to N, the shutter interval period is 100 seconds, or 50 seconds if the Slide Switch is set to TIMELAPSE (See Table 1). Every time the buttons are pushed on, or the mode is switched or the Slide Switch is slid, the selected shutter interval period will restart.

Swinging Angle

Swinging Angle: To avoid the shutter release cable to be twisted after a long period of use under the Astrophotography application, Star Adventurer will reverse after reaching 360° rotation. That is, for Mode and 0.5X, Star Adventurer will rotate within a 360° range. For the other modes, in order to provide more attractive scene while filming for time-lapse photography, under Time-Lapse application like Mode 2X, 6X and 12X, Star Adventurer will rotate within 60° (See Table 1). Every button pushed or mode changed will reset the start point of the swinging angle. For example, when the Mode Dial is at 6X and Slide Switch is at N, the current position while we enter the mode will be the midpoint of the swinging angle. That is, it will rotate to the right first until it reaches 30°, then it will reverse until it reaches 60° (Fig 21), then swing within the 60°. If you push the buttons, the position at which you release the buttons will become the new midpoint of the 60° swing. If the switch is at S, it will rotate to the left first until it reaches 30°, then reverse the direction until it reach 60° (Fig 22).

Auto-Guiding

Auto-Guider: Star Adventurer also contains auto-guiding interface to accept single axis (RA axis) auto-guiding signal to provide more accurate celestial tracking for better quality of astrophotography. The RJ-12 6-pins outlet is for connecting an autoguider. It is compatible with any autoguider with a ST-4 type interface. This function only works in Mode . For other modes, the auto-guiding signal has no effect.

USB Port

USB Port: Star Adventurer contains an USB port (Type Mini-B) to support external USB power and Support firmware upgrade. Please refer to "Firmware Upgrade".

Motor Status Detection

Motor Status Detection: If the motor stalls (rotation speed doesn't reach 10% of the targeted speed) over 5 seconds, in order to protect the motor and the mounted equipments, Star Adventurer will stop the motor and indicate "Motor Error" through flashing the LED on the buttons. Pushing buttons or switching mode will restart the motor and restart the detection. Moreover, if the motor speed error is over 5% ( if it is not within the of the targeted speed), Star Adventurer will indicate "Motor Error" through flashing the LED on the buttons, but it will not apply any change to the motor control.

LED Indication

LED Indication: Star Adventurer has LEDs under the buttons to indicate the current status. There are three different ways the LEDs will light up. If the LEDs don't light up, the Star Adventurer is not in working mode.
Normal Status: LED will light up slightly, continuously.
LED will light up slightly to provide light source in the dark when the motor status is normal and the power level is normal.
Warning Status: LEDs will blink at a 0.5 second rate in two cases:

1. Firmware is upgrading: While the user is updating the firmware, LEDs on the Star Adventurer will blink to warn users not to turn off the power.
2. Battery Low (The battery voltage is lower than roughly 4.5V): Star Adventurer supports most of the AA batteries. When using rechargeable Nickel Metal Hydride (Ni-Mh) batteries, please replace the batteries when it indicates low battery in order to protect the batteries from over discharging. When using Alkaline batteries, the system will run normally for a while after indicating battery low.

Motor Error Status: LED will blink at a 3 times per second rate in two cases:

1. Motor speed Accuracy violation: The motor speed error is over 5%. If this keeps happening, the user may need to check for overload (Max load is 5kg) or if the battery level is too low.
2. Motor stall: the motor stalls over 5 seconds. May be caused by external interference. Please check if the mount is blocked by an external force.

Polar Alignment

Use the built-in Polar Scope to complete the polar alignment. First, remove the Polar Scope Cap and insert the Polar Scope Illuminator (Fig 23). Rotate its Power Dial to turn on the power to illuminate the Polar Scope, then keep rotating the Power Dial until reaching the best illumination. (Calibrate the Polar Scope as needed. Please refer to "CaIibrate the Polar Scope")

For observing in the Northern Hemisphere: find Polaris (the brightest star near the North Celestial Pole) in the polar scope by adjusting the angle of the (optional) Equatorial Wedge or tilt-head on the tripod. Use third party PolarisFinder application or APP to find the corresponding orientation of Polaris in the Polar Scope by simply entering the Date, Time, longitude and latitude of your observing location. Then move Polaris to that corresponding position in the polar scope by using the fine-tuning movements of the Equatorial Wedge or by moving the tilt-head on your tripod(Fig 24). If you cannot acquire the application tool to find the orientation of the Polaris, please refer to the "The Orientation of Polaris in Polar Scope" in the following portion.

For observing in the Southern Hemisphere: locate in the polar scope the 4 dim stars (Around Magnitude 5 to 6) which form the pattern "Octans" (see drawing in the polar scope as Fig 25). Align the orientation of the "Octans" drawing to the 4 stars. Then move the 4 stars to the 4 small circles of the "Octans" drawing by using the horizontal adjustment knob to fine-tune the Equatorial Wedge or by moving the tilt-head of your tripod.

The Orientation of Polaris in Polar Scope

As Polaris is not located exactly at the North Celestial Pole, we can see it orbits the North Celestial Pole in a polar scope. The large circle seen in the center of the pattern in the Polar Scope is a representation of Polaris' orbit around the North Celestial Pole. When performing the polar alignment process, it is necessary to determine the orientation of Polaris on the circle. We can use the following 2 methods to get the orientation:

1. Locate both Polaris and Kochab in the sky near the North Celestial Pole. The relative position of Kochab to Polaris is an approximation of the orientation of Polaris in the polar scope. For example, if Kochab is at the 11 o'clock direction of Polaris, then Polaris should also be placed at the 11 o'clock position on the reticle circle.
   
2. Use the built-in Date Graduation Circle, Time Graduation Circle and Time Meridian Indicator to find the orientation of Polaris in the Polar Scope following the steps described below:
   1. First rotate the Wedge and adjust the latitude to bring Polaris within the field of view of the polar scope
      
   2. Then rotate the Date Graduation Circle to align Oct 31 to the 0 of the Time Graduation Circle and turn Eyepiece/Mounting Platform to align the Time Meridian Indicator to the 0 of the Time Meridian Circle (Fig 27). This is the date and time when the orientation of Polaris is directly below the north pole (6 o'clock).
      
   3. See through the eyepiece to make sure the pattern is oriented as shown in Fig 28. If the pattern is rotated, please refer to "Calibrate the Polar Scope".
      
   4. Adjust the Date Graduation Circle first according to the difference between the standard time meridian of your region and the observing site. For example, if you are in Prince Rupert, Canada which is 130° west, then you have to turn the Date Graduation Circle to make the Time Meridian Indicator point to West 10 (which is 130° - 120°).
      
   5. Match the Date Graduation Circle with your observing time by turning the eyepiece/ Mounting Platform. Please DO NOT rotate Date Graduation Circle directly at this step. For example, if your observing date is March 4 and observing time is 8:00PM. (Standard Time, that is Daylight Time -1 if applied.)
      
   6. Then Put Polaris at the of 6 0'clock position in the FOV of the polar scope to finish the polar alignment.

Example for Astrophotography for Celestial Tracking

1. Assemble the tripod and Star Adventurer according to your need. Then finish the polar alignment.
2. Mount the camera or telescope. Install the cables (Shutter Control Cable and auto-guiding) if needed.
3. Slide the Slide Switch to N if you are in northern hemisphere.
   
4. Rotate the Mode Dial to Mode . The LED on the Mode Dial will light up Mode . The LED in the buttons will light up, too. The Star Adventurer will start tracking the celestial objects at sidereal rate (86164 seconds per revolution, about 23.9 hours per revolution). At the same time, it will start to control the camera by activating the camera shutter release function with an interval period of 100 seconds (as if you were pushing on the shutter release button of the camera for 99.5 seconds and not pushing for 0.5 second and pushing again for 99.5 second etc.)
5. You can push the buttons to move the Star Adventurer at a higher speed (12 times sidereal rate) to approach the targeted object in RA direction. When you reach the targeted object, release the buttons. The Star Adventurer will continue celestial tracking and restart the shutter interval period of 100 seconds.

Example for Time-Lapse Photography in Mode 12X

1. Assemble the tripod and Star Adventurer according to your need.
2. Assemble the camera and connect the camera and Star Adventurer with the Shutter Control Cable.
3. Slide the Slide Switch to position N. Rotate the Mode Dial to Mode 12X.
4. Star Adventurer will start to rotate to the right with a speed of 2 hour per revolution. When it first reaches 30° it will start to reverse until it reaches 60°. It will repeat the swing within this 60° (Fig 32). At the same time, it will start to control the camera by activating the camera shutter release function with an interval period of 2 seconds (as if you were pushing on the shutter release button of the camera during 1.5 seconds, and not pushing during 0.5 seconds and pushing again during 1.5 seconds etc.).

8. If you encounter power loss during the firmware update, you can just repeat from Step 3 to Step 7 after restoring the power.

Specification

Calibrate the Polar Scope

Before using the Polar Scope for polar alignment, the Polar Scope itself must be calibrated to ensure the pattern in the Polar Scope is aligned to the mount's R.A. axis. The following steps will outline how to calibrate the Polar Scope. Calibrating during daytime is strongly recommended:

1. Choose a fixed object (the Polaris at night, or a faraway object in daytime); orient Star Adventurer to put the crosshair of the Polar Scope exactly on the chosen object.
2. Rotate the mount in R.A. axis for half a turn.
3. If the object remains exactly behind the crosshair in the Polar Scope after the rotation, then it means the Polar Scope is aligned to the R.A. axis and no calibration is needed.
4. If, during rotation, you see the object wandering off, calibration is needed. You should rotate the Star Adventurer to find the point where the object is at the longest distance from the crosshair center, and then you should move the crosshair halfway towards the object (Fig 34), using the 3 tiny adjustment screws on the side of the polar scope (Fig 33). A 1.5mm Allen wrench is needed.
   
   
   Adjusting with the very small allen screws is delicate. Read the note below.
5. Repeat steps 1 to 4 a few times until the object remains at the center of the reticle when rotating the mount in R.A. axis.
6. Turn the Date Graduation Circle to align Oct 31 to the 0 of the Time Graduation Circle. Then hold the Date Graduation Circle and turn the eyepiece/Mounting Platform to align the Time Meridian Indicator to the 0 of the Time Meridian Circle (Fig 35). Then, when looking through the eyepiece, you should see the pattern aligned as shown in Fig 36. If the pattern is oriented differently, then scales need readjustment. To readjust, turn the Date Graduation Circle to align Oct 31 to the 0 of the Time Graduation Circle. Then hold it and turn the eyepiece/mounting platform to orient the pattern in the position shown in Fig 36. Loosen the Time Meridian Indicator Calibration Screw and move the meridian indicator to align it to the 0 of the Time Meridian Circle without turning the Date Graduation Circle and Eyepiece/Mounting Platform. Tighten the Time Meridian Indicator calibration screw. See through the eyepiece. Now the pattern should still be in the right position.
   

Note:

• When adjusting the Allen screws, loosen one screw only ¼ of a turn, and then tighten the other two gently.
• Do not over tighten the Allen screws; it might damage the pattern plate in the polar scope.
• Do not loosen one screw completely or loosen more than one screw at a time; otherwise, the pattern plate in the Polar Scope will be disengaged and further adjustment is impossible.
• If the pattern plate does disengage, remove the Polar Scope's eyepiece by turning the Knurled Ring counterclockwise and then engage the pattern plate again.
• It is recommended to do this calibration at daytime, aiming at a point object (such as a distant rooftop) because the delicate operation with the tiny allen screws is even more delicate in the dark.

Fine-Tuning Mounting Assembly

The Fine-Tuning Mounting Assembly connects a telescope to Star Adventurer and allows rotation in the other direction (at 90°, DEC direction). You can adjust the tightness of the rotation with the clutch knob. You also can fine-tune the camera or telescope orientation slightly in DEC direction by using the fine-tuning knob. You can also remove the Fine-Tuning ¼" Mounting Element from the dovetail and then mount two ball heads on the dovetail to carry two cameras or one camera and another instrument. You can also use the Fine-Tuning ¼" Mounting Element at one side and use ball head at the other side. You can implement various combinations to fit your needs.

Equatorial Wedge

The Equatorial Wedge is a device to adjust the latitude for Polar Alignment. Rotate the Latitude Adjustment Knob can adjust the latitude of the Star Adventurer indicated by the Latitude Indicator. The range is from 0° to 70°. The Horizontal Adjustment Knob can adjust the Wedge to rotate to right or left horizontally. The Horizontal bubble is for checking if the base plate of the wedge is horizontal. The accuracy is 1°.When you install the Mounting Plate on the Star Adventurer, Make sure the Stopper is facing forward the Fig 38 shown to avoid equipment sliding down before you fasten the Locking Knob.

NEVER USE YOUR TELESCOPE TO LOOK DIRECTLY AT THE SUN. PERMANENT EYE DAMAGE WILL RESULT. USE A PROPER SOLAR FILTER FIRMLY MOUNTED ON THE FRONT OF THE TELESCOPE FOR VIEWING THE SUN. WHEN OBSERVING THE SUN, PLACE A DUST CAP OVER YOUR FINDERSCOPE OR REMOVE IT TO PROTECT YOU FROM ACCIDENTAL EXPOSURE. NEVER USE AN EYEPIECE-TYPE SOLAR FILTER AND NEVER USE YOUR TELESCOPE TO PROJECT SUNLIGHT ONTO ANOTHER SURFACE, THE INTERNAL HEAT BUILD-UP WILL DAMAGE THE TELESCOPE OPTICAL ELEMENTS.
