Bluetooth Version Portable Equatorial Mount Built-in Automatic Shutter and Linkage Shutter Module Astronomical Accessory

Description:
- All metal high load-bearing structure, sturdy and durable, compact in size. The body is made of aluminum alloy, with a shell size of 5.0x5.0x10CM and a thickness of 2mm. The internal frame is cast of stainless steel material, and the main output shaft is made of CNC stainless steel material with a specification of 1/4 inch thread and length of 8mm. The front and side panels are laser cut with holes. It can support up to 5 kilograms load of camera and lens, and equipment weighing over 5 kilograms requires the balance wheels (52) and counterweight (35) for use (not included, please prepare by yourself).
- The specification of the secondary shaft is M5 with an internal thread depth of 10mm. The speed range of the main and secondary shafts covers 0.02 to 25 revolutions per minute. The bottom of the equatorial instrument is connected to the tripod gimbal through an L-shaped quick mount plate. The L-shaped quick mount plate can be disassembled and installed in any direction. The top of the equatorial instrument has an M5 expansion interface, which can be equipped with a K50 quick mount plate to adapt to all latitude adjustment seats and hydraulic gimbals.

Key Features:
- Built-in Bluetooth module.
- Built-in green laser module.
- Built-in automatic shutter and linkage shutter module.
- The body comes with a one click start button for the Northern Hemisphere star speed.
- All power banks with 5V output can be used as power supply devices, and the mobile software controls tracking speed, shutter button, and exposure time. (Note: Currently only supports for Android software control. For iOS users can switch tracking speed with infrared remote control)

The software can achieve:
- Scheduled shutdown.
- Custom speed.
- Northern and Southern Hemisphere tracking.
- Tracking of stellar velocity, solar velocity, and lunar velocity.
- Jogging the tracking of the northern and southern hemispheres, accelerating and decelerating.

After connecting the camera with a 2.5mm shutter cable, the following can be achieved:
- Automatic timed shutter (P, A, M)
- Camera and equatorial mount linked shutter (P, A, M)

The duration of stable tracking of a single long exposure lens measured for each focal length lens in the case of coarse polar axis is as follows:
- 14mm lens: 24 minutes
- 20mm lens: 17 minutes
- 24mm lens: 14 minutes
- 35mm lens: 10 minutes
- 50mm lens: 07 minutes
- 85mm lens: 04 minutes
- 135mm lens: 2 minutes 30 seconds
- 200mm lens: 1 minute 40 seconds
- 300mm lens: 1 minute

Bluetooth Control Instruction:
Connect Bluetooth:
- First, power on the equatorial instrument, turn on the Bluetooth power, and the Bluetooth indicator light will flash. Open the Bluetooth settings list on your phone, click on the search device, click on JDY-33-SPP to pair, and use the pairing password 1234. After pairing is complete, open the control software, click on the search icon in the upper right corner, and a pop-up window will appear at the bottom displaying the words "successfully connected", indicating that the connection is complete.

Single Speed Tracking:
- After connecting, press the corresponding button according to the target to be photographed. Taking the Northern Hemisphere starry sky as an example, press [Star] → [Northern Hemisphere] in sequence. Click the 'Close' button to terminate the operation.

Timed Single Speed Tracking:
- After connecting, enter the desired tracking duration in the input box above the hourglass icon, such as 0432. After entering, click on [Star] → [hourglass icon] → [Northern Hemisphere] in sequence. The equatorial tracker automatically shuts off after tracking the stellar velocity for 4 hours and 32 minutes.

Automatic Shutter Shooting:
- Connect the camera to the equatorial using a 2.5mm shutter cable. Set the time parameters for shooting and interval in the "Automatic Shutter" line of the software. After setting, press "Automatic Shutter" -> "Star" -> "Northern Hemisphere" in sequence. Then, the equatorial and camera will track and shoot the aligned Northern Hemisphere starry sky area at stellar speed.

Linkage Shutter Shooting:
- (This function is commonly used for large-scale time-lapse shooting of rotating mirrors, because in this mode, the equatorial camera rotates intermittently, and in order to maintain clear scenery, the camera's shooting is also controlled in the gap when the equatorial camera stops. In this mode, the equatorial camera does not need to align with the polar axis, but can freely fix the path of the mirror as needed, usually facing upwards.) Connect the camera to the equatorial camera through a 2.5mm shutter cable, and set the stop and rotation time and speed parameters in the "Custom" and "Linkage Shutter" lines of the software interface, as shown in the following figure. After setting, press: [M-mode linkage]/[B-door linkage] → [Interval rotation] → [Custom] → [Northern Hemisphere] in sequence; At this point, the equatorial instrument will rotate clockwise, stop and shoot images for 32 seconds, rotate for 3 seconds, and repeat the cycle.
