Mars is small currently range of 4.5 arc sec. Small for my 8 inch dob reflector, but monthly increases and nearing summer should be getting some good looks.
Early checks a good idea as the polar cap believe is larger then before it reduces in size w/Martian summer.
Fall reaches max over 20 arc seconds, but beware least here in midwest plenty of overcast that time of year.
I'll check it as early as March, polar cap suppose to be at a good angle thru the encounter!
