简介
Credit: The M51 Whirlpool galaxy photography is shot by Adam Kohorn using iPhone 13 Pro Max.
Take video using any camera app and export to videoStack(This app) for stacking. Stacking increases the signal of the photograph and reduces the noise. It makes galaxy and nebulae reveal their colours and structure. The app uses the computation power of the phone and integrates all the individual steps of desktop-based astrophotography into a simple phone app. It works for video taken on a manual or goto telescope.
A Tiff file for the stacked result is automatically saved for your further image processing.

Our Story
Currently it is expensive and time consuming to do astrophotography. In the simplest setup, you need to buy a tracking mount because of the Earth rotation. You need special camera to take interval shot of the sky. Then you need to upload these photographs to desktop software to align and stack them. Now you have a new way to photo deep sky object. You take a video and we will do the rest! The app includes 3 demo videos. The Milky Way video is taken by Daniel Mendell. And the M31 and M42 video is taken by the developer.
File Size
VideoStack can do unlimited time stacking but the file size of the video can be large. It takes up space in your phone. First, use videoCam app to video efficiently. Choose the right frame per second to reduce your video size. For example to shoot the Milky Way, at resolution 4032 x 3024, 1 frame per second, it uses 50 Mb of phone disk for 1 minute of video. So a 5 minute video takes about 250Mb memory. To shoot nebulae or galaxy in a telescope, at resolution 4032 x 3024, 3 frame per second, it uses 150 Mb of phone disk for 1 minute of video. It is possible to half the video size if you choose a lower pixel resolution in VideoCam iOS app. Then export to videoStack app for stacking.
Have fun!
