My first attempt with planet Neptune, with my 10inch telescope and DMK 21AF04 with barlow 5X at barlow projection protographic method around f/43, I use Astronomik filters RGB.
I dont understand why in my photo the pole has a different color, the north pole is a little green and the south pole is a little red.
And finally why my Triton is green???
I use registax to processing my 3 AVI files with about 2300 frames/AVI files, for RGB addition the MaximDL and final processing in PS 9 for crop & resize.
