Ok..so I took a toilet paper roll and looked at the waning crescent moon
this morning at 4:30 local time. I could see enough
earth shine to complete the disc...there is NO WAY Mars comes even close
at
120 X's magnification to being a comparable
angular diameter in the EP....the math says yes..my eyes say NO! Go
figure...

That's why it is concidered an illusion - a direct comparison (the magnified
view of Mars in one eye, the non-magnified view of the Moon in the other)
eliminates the illusion.

Clear Skies,
