Note: - The app is designed for seestar image of resolution 1080 x 1920 pixels. Larger image will need longer time to load and remove stars. Requirement: - App works best with 4G RAM and above. If the device has less than 4G RAM, it will use lesser weights for AI and produce degraded image. - Image is optimised at 1920 x 1080 pixels. Support: Please write to ustransit74@gmail.com.
