Nearly all images were taken from my backyard (Bortle 5) with telescopes atop a permanent pier. After cropping, newer images have been resized down to 3000 pixels along the long edge. The latest images were taken with cooled monochrome cameras and narrow band filters. Older images were taken with color astro cameras and dual narrow-band filters.

Raw FITS images were stacked with AstroPixelProcessor, registered and cropped with Siril followed by PixInsight processing. BlurX, NoiseX, and StarXterminator were applied before statistical & star stretching (SetiAstro scripts w/in PixInsight). Subsequent processing could take 1 of several paths: (1) creating RGB images for background correction (PixInsight), generalized hyperbolic or modified arcsinh stretching, blackpoint adjustment (Siril), and application of curves (PixInsight). (2) SetiAstro's PerfectPalette picker tool (PixInsight) was used to create multiple images ranging from SHO, Realistic1/2 or Foraxx. These options were background corrected and followed similar stretching as noted.

   Hint: after the image opens, some browsers will force the image to fit within the existing window size. Clicking on the image will reveal its full size (3000 pixels on the long edge).
