Mars will have an angular diameter of 14" of arc, at opposition on th 3rd March.Surprisingly, it only will take a magnification of 130x, to make its disc to appear, as the full moon is to the naked eye. Though in practise, one would use around twice that magnification, and up to get the best visual out of Mars at this opposition. Of course, seeing is all important. Also at larger apertures one would expect to pick up more surface detail.
