A little recap of Neptune and Triton over 2 months, given the lack of details I focused on Triton and the color of Neptune.
The different colors of the satellites are, I think, dust that are more or less concentrated in the atmosphere.
My usual equipment, ie 300mm F4, powermate 5x, adc ASH and ASI224MC
My catch settings often vary from 75ms to 200ms, the gain between 500 and 550 (600 max).
There are 11 captures on an image of Neptune made November 17 in color (anti ir filter):
