The Repair module attempts to detect and automatically repair stars that have been affected by optical or guiding aberrations.
Repair is useful to correct the appearance of stars which have been adversely affected by guiding errors, incorrect polar alignment, coma, collimation issues or mirror defects such as astigmatism.
The Repair module allows for the correction of more complex aberrations than the much less sophisticated 'offset filter & darken layer' method, whilst retaining the star's exact appearance and color.
The repair module comes with two different algorithms. The 'Warp' algorithm uses all pixels that make up a star and warps them into a circular shape. This algorithm is very effective on stars that are oval or otherwise have a convex shape. The 'Redistribution' algoirthm uses all pixels that make up a star and redistributes them in such a way that the original star is reconstructed. This algorithm is very effective on stars that are concave and can not be repaired using the 'Warp' algorithm.
However the Synth module can physically model and emulate most real optical systems and configurations to obtain a desired result.
It allows you to shrink stars, tighten stars and better color stars.
