I see color errors on Mars (red on top, blue on bottom) which are no optical errors, but a result of atmospheric refraction.
Maybe starting to get a bit low, less than ideal I guess. However you've got to factor in the poor Jetstream conditions overhead, the high level cirrus cloud covering the sky, the gusting wind, it's an iPhone camera not necessarily aligned perfectly with the eyepiece on a 2.8m wobbly stack in a light polluted suburban backyard with no shroud or light baffling, operated in "close enough, she'll be right" mode .
