Welcome to Eise.app
A planetary image stacker for lucky imaging
Turn your blurry and shaky videos of planets, Moon, or Sun into one stacked and sharp image using lucky imaging - a classic astrophotography technique.
- Select one or more SER or raw AVI files for stacking followed by post processing. Multiple video files allow you to open batch stacking mode.
- Select one video file (AVI, MP4, etc.) for stacking followed by post processing.
- Select multiple image files (TIFF, PNG, JPG, etc.) for stacking and post processing.
- Select one image file to directly open the post processing with that file.
When stacking, Eise.app analyzes, crops, centers and ranks all frames by sharpness and circularity, and it drops frames automatically that are (almost) cut-off.
Tip: For Moon or Sun surface closeups, select "Surface" mode above to handle larger frame-to-frame drift.
Beta: Batch stacking and post processing workflow
Batch stacking and processing is now in beta. Select multiple SER or raw AVI files, and Eise asks you how you want to stack it. The post processor applies all settings to all stacked images at once.
