This app is an ultra high sensitivity video application and can take pictures of the trajectories of stars moving in the night sky. Each frame of video is created as a bright image created by comparative brightness synthesis of up to 10 images. (Comparative brightness synthesis is a standard technique for taking beautiful starry sky photographs.) You can take video of the starry sky for a long time (5 minutes to 5 hours) and take pictures of the stars moving around the North Star along with the rotation of the earth. This is not just time lapse. Since it takes pictures with ultra-high sensitivity one by one, it takes video brightly even in the dark night. (Because shooting with compressed time, it will be fast-forwarded.) We recommend that fix the smartphone with a tripod etc. · Brightness: From brightness in the daytime, brightness suitable for night view, and even brightness to capture the starry sky can be specified continuously. · Recording time: It can be specified consecutively from minimum 5 minutes to 300 minutes (5 hours). · The time lapse interval (shutter interval) is automatically set and displayed from the brightness setting value. · The playback speed magnification can be specified continuously from 10 times to 300 times. The larger the magnification, the less the playback time. · Frame rate and playback time at playback are automatically calculated and displayed. If you cancel while photographing, it saves the video taken until then. Still images are saved at intervals of 10 frames of video.

AstroEdit Planet is a very simple 4in1 app to stack planetary video. It will automatically crop the video and center the planet. It works on video that has planet moving across the view or planet centred in the view. When you open the app, it auto loads a sample Saturn video. Tap Stack button to begin! PlanetEdit integrates the four legacy desktop software into a single delicate mobile app. Traditionally, astronomer has to install 4 different programs to process planetary video. They are (in process sequence): 1. PPIP for cropping video 2. AutoStakkert! for stacking frames 3. Registax for wavelet sharpening 4. Photoshop for RGB alignment and coloring Features: - Open video or image. Accept all format recognised by the Photo app. In addition, it open .ser files. First, copy them to the Files app. Then tap Open button in PlanetEdit app. Choose Open Files App. Tested for a 3.5Gb .ser file. Now for .avi file, copy to your the Photo app or the Files app. The .avi has to be the standard accepted by the Photo app. If it is accepted by the Photo app, it will be visible in the Photo app. - Auto crop video and center frame. - Auto set alignment points for stacking. - Lucky stacking slider. - Real time update of stacking result. - Use 2 finger to pinch zoom, 1 finger to drag and 1 finger to long press to compare a frame(best quality). - RGB alignment. - Basic image processing like saturation, bright, contrast and hue. - 5 wavelet layers to extract detail and denoise. - Save edited image to photo. PlnetEdit has been tested for video capture in seestar S30, S50 smart telescope, ZWO camera, refractive telescope 80mm and Dobson 200mm telescope.
