The POLARIE U app is an app dedicated to the POLARIE U star tracker offered by Vixen. Shooting night skies is easy if only the POLARIE U. With the use of this app, however, you will enjoy creating a time-lapse movie of a higher level. Major features - Various speeds of rotations. (10x of the sidereal tracking rate at the maximum.) - The rotation speeds are available to set in the Custom Mode. - Control a camera shutter with an optionally available shutter release cable. - The motion of a POLARIE U can be linked with the shutter control (Shoot-move-shoot function). - Tracks the motion of stars accurately and the stars appear no trails in long exposures. - The bracketed imaging mode is available. It is effective in capturing fainter celestial objects such as diffuse and emission nebulae and it allows for creating HDR images using a stack of different exposures. A photo with a dynamic range wider than by a single shot will be a result. - The night vision light is available to use with either red light color or incandescent light color. - The screen colors are available for daytime use and nighttime use.
