      California Nebula (NGC1499) Highlights

      I'm a fan of the PI MultiscaleGradientCorrection process and I'm pleased that PixInsight has released the latest update that covers most of the northernhemisphere except for the SII band. Even so, the OIII band data is exactly what is needed here to tame the gradient produced by xi Per and allow the fainter areas on that side of the nebula to show in the OIII band.
