Description

I captured some fairly decent data despite mediocre seeing and transparency as of late. The weird thing was that my RAW files almost looked better than the initial stacked result. I went through several iterations using Weighted Batch Preprocessing and then the classic method. I got similar results - a weird checkerboard pattern on the stacked result. After a bit of research, I discovered that my registration interpolation method needed to be changed to "Nearest Neighbor." It made all the difference.
