Hi,
I had had relatively good seeing for my first observation of Mars. Atmospheric dispersion would come and go but still, Mars showed a good amount of detail. At this point Mars' apparent diameter is quite small at 9.4".
I used my 6" refractor at 400x with a Sirius Optics VFS filter. I consider some settings on the VFS filter to the best filter available for Mars viewing.
I sketched mostly with a 4H pencil and a stump. If Mars is showing this much detail now, I can't wait wait till later on during this opposition as Mars is quite high in altitude compared to the 2003 opposition.
Best of luck to everyone with your own observations.
