Measured tracking accuracy (non-limit value) - Full frame camera with subjective single exposure without dragging lines. - 70mm lens: 5 minutes - 200mm lens: 1 minute - 300mm lens: 60 seconds Attention: Equatorial mount tracking time is affected by a variety of factors. Misalignment of the polar axis, wind, tripod shaking, etc. can cause star trailing. The above data were obtained with the pointer roughly aligned with the polar axis. The data is for reference only. If the polar axis is aligned precisely, the actual exposure time of a single photo will exceed the above data. Specification: - Net weight: 360g - Product size: 83 x 72 x 82mm - Maximum load capacity (without counterweight): 3kg - Shell material: PETG-CF - Power supply requirement: USB-C 5V 500mA, support USB-PD 9V (use it for the camera weight over 2kg) Package Included: - 1 x Equatorial Mount - 1 x Ball-head Gimbal The shell of the equatorial mount is made of PETG and carbon fiber (CF). This Equatorial Mount is designed based on an open-source scheme. it uses EESP32S dual-core main control chip. It supports stellar speed, moon speed and custom rotation speed. It also supports switching between the northern and southern hemispheres. This Equatorial Mount can be used as a gimbal head for time-lapse photography. No need to download an APP. It is ready to use when it is powered on. And it can be powered by a power bank. Type C port to supply power. Without built-in battery. Your gimbal with a standard quick-release plate clamp can be used directly, thanks to a 38mm quick release baseplate at the bottom of the equatorial mount. The output shaft is a standard 1/4-inch screw, and a ball head is required for the connection to a camera. Since most of the ball head bottom screw holes are 3/8 inches, please purchase a 1/4 to 3/8 screw sleeve separately. Warning: All screws are coated with threadlocker, and disassembling them without permission will cause damage to the equipment.
