Linear Image Quality Enhancements

Step 1: Image Transformation

updated: 2025-09-28


Purpose

Change the picture properties by cropping, rotating, and resizing.

IMPORTANT: Image transformation will destroy its astrometry data. Therefore, it is highly recommended that you apply a Plate Solve afterwards, as this data is required for later processing steps.

No additional cropping is required if you choose one of the *_autocrop.XIFS files  after a batch pro-processing step. Also, these files are already  plate solved.

Input

The integrated linear Master Light frame from the Image Alignment and  Integration 

Output

An image that contains the essential elements and hides distracting edges for further processing
