This page displays before and after comparisons of images acquired at the Chamberlain Observatory and post-processed with old vs newer methodologies. The differences are the result of using the massively improved PixInsight Weighted Batch Preprocessing (WBPP) script, Russ Croman’s BlurXterminator, NoiseXterminator and StarXterminator as well as Bill Blanchan‘s Pixelmath scripts for narrowband normalization and star shrink. The old method used the more traditional PixInsight processes for stacking, registering and integrating subframe images, and scripts for deconvolution, noise reduction and curves adjustments.
Most notable in these comparisons is the enhanced details, tighter and rounder stars, more structure visibility, and fewer artifacts. With BlurXterminator, deconvolution can be applied to any type of deep sky object with greater precision and ease.
The same raw data was used in both before and after images.
Old process image is on the left. New process image is on the right.
