About this image

IR image with 610nm filter. Triton at top and exposed for separately at 100msec and gain 500x. Planet 26msec exposure at same gain. No spots or details to report.

Anthony Wesley kindly helped me with the processing on this one, using his Ninox Aperture algorithm to quality sort and select the best frame set- doing a better job than Autostakkert or Pipp on this difficult low brightness object.
