someone seen this mars email again- we know its all crap- but they said seeing mars at 25 arc seconds @ 72X is the same as a naked eye moon- i think thats crazy -no way will mars the size at 72X- i got this replay
""When in doubt, do the math. 200x25=5000 arcseconds. The naked-eye Moon is 1800 ascseconds in diameter. So that's more than enough magnification to make it that big. How much magnification would do the job? 1800 / 25 = 72x So that claim is accurate.""
i think the above math is flawed, i dont think angular size magnification work this way- if it did- 40 arc second jupiter would be 12,000 arc seconds at 300X- or over 3.3 degrees in the EP
