2023-11-07 ========== The FITS images are selected for best seeing from 10 in each filter taken at Mt. Lemmon near Tucson, Arizona. Telescope: ULMT 0.6 meter Ritchie-Chretien Camera: ZWO ASI 16200 9576x6388 pixels Scale: 0.16 arcsec/pixel Resolution: ~0.2 arcsec Exposure: 200 milliseconds Filters: Sloan i', r', and g' Date of observation: 2023-11-08T07:05:57 for RP image 15. The dates are in the FITS headers. The FITS images are raw data that were processed in AstroImageJ to produce the color composite images in PNG and JPG formats. Color maps i' to red, r' to green, g' to blue emphasizing the near infrared as red. These images are shown with north up and west to the right. The satellites are visible in order from east to west: Callisto Ganymede Io Europa (west of Jupiter) The color image is a composite created with AstroImageJ where the Sloan i' is red, the r' is green, and the g' is blue. The original FITS images were cropped to a nominal 600x600 pixel frame, aligned in AstroImageJ, processed with a 3-pixel unsharp mask, and stacked to produce the color image.
