Features of AP Photo Guider
- Setting up is easy. Mount your camera on the AP Photo Guider with the provided dovetail slide bar GP via a ball head sold commercially. If a heavy camera is mounted, the installation of a supplementary counterweight bar and a counterweight 1 kg will increase the stability of the AP Photo Guider.
- The Polar alignment scope is provided. It enables you to align the AP Photo Guider to the celestial pole as accurately as 3 arc minutes or less. The Polar alignment scope’s reticle will be illuminated in red light and it turns off automatically after a certain interval.
- There is an accessory shoe on the body to install the Polar Meter sold separately. The Polar Meter allows for a quick setting of the AP Photo Guider for polar alignment when Polaris is hidden and not seen directly in your observing site.
- The AP Photo Guider has a USB port (USB Micro-B) for power supply and external USB mobile batteries (over 0.5A output) are available. The batteries are not included.
Note: The batteries for the AP Photo Guider are not available from Vixen.
