Correct Aberrations

Current beta

This mode doesn’t yet fully remove all aberrations. Until the fix arrives, use Deblur and recover detail with an Amount of 0.40 or higher; see Known Issues.

This mode removes:

• defocus, including field curvature,
• spherical aberration,
• coma,
• astigmatism,
• trefoil,
• chromatic aberration,
• elongation from guiding errors, wind or mount problems.

It leaves blur from atmospheric seeing in place, so the image keeps its overall sharpness. There is nothing to set: the correction is fully blind.

Run it on linear data, before any stretch. Use it when stars toward the edges and corners are misshapen, when stars carry color fringes, or when they are stretched in one direction.
