AstroShader is an astrophotography app for capturing, stacking and editing. All you need is a stand, tripod, telescope or rock (to lean your phone on).
AstroShader lets you align and stack live during the image capture process. You can also align and stack images from you Photos library. No need to transfer images to a computer to align and stack them separately (but there is a built in intervalometer if you need it).
To take an image follow these steps:
• Use a stand, tripod, telescope mount (or lean your iPhone on a rock).
• Zoom in on stars and set focus manually, or use autofocus.
• Set the exposure time, ISO and white balance, or leave to auto-exposure.
• Set the number of exposures to be automatically aligned and stacked.
• Calibrate your images from the edit tools.
• After the capture is complete you can edit and save your image—including as 16bit TIFF.
• You can open images directly to use the edit tools in AstroShader - rather following a new image capture.
