Annotating a highly processed image in PixInsight

Deep Sky West Orion Mosaic Project

• Rokinon 135mm lens, f 2 on QSI 583 wsg5

• 9 panels cover most of Orion• My image is a cropped version

of a panel 5 and 6 mosaic• Highly processed• Would not plate solve

Processed, nonlinear images often fail to plate solve

Linear image plate solves

Layer and “project” (screen mode) the annotation onto the processed image in PS

An easier method… transfer the FITS header information(https://www.cloudynights.com/topic/608653-annotating-highly-processed-images-with-pixinsight/)

Then annotate the “solved” nonlinear image
