Mars revisited

As I was unhappy with the processed result of Mars december 11th, I revisited the image.

That lead to a more natural result, still lots of subtle details without over sharpening. The color has maybe a bit of a green hue I´m told.

Equipment was a C14 XLT, ASI290MM, Baader RGB filters, XPRESS Filterwheel ; No Barlow used ; one single RGB run

Mars as observed underneath the jetstream

Seeing conditions (air turbulence influencing the visisbility of planetary details) are hughly dependend on the jetstream. Chances are that when the jetstream is directly above your location, that barely any surface detail is visible on moon or planets.

It can be however a very clear night. Also stars don’t have to ‘jump’ up en down and might not be seen twinkeling by the naked eye. An example is the RMS of guiding – this RMS can be < 2 arc sec and seemingly indcating good seeing, while actually the seeing is exteremely ‘fast’, and blurring out planetary detail.
