Dear Science and astronomy friends,

Many times we been asked that "will we be able to see VENUS transit without any
optical aids?" ANSWER is so simple but different for different individuals.!!!
Generally 5" arc size are appreciated for recognise the letters, but line
thickness or DOTs of 1 to 2 " arc size can be seen by good eyes.

* (NEVER EXPERIMENT to see This by Telescope or Binoculars and without proper
filter protections it is DANGEROUS to YOUR EYE & may harm 2U.)

Different for individuals means depend on the persons eye's adaptability. and
practice. we some time do see Venus (Now a days) in a Broad day light and some
time even Jupiter. For such an experienced person VENUS transit is visible
without optical aids. (always use proper filters to protect your eyes)

Here is the Sun disk area of 25mm = 1 Inch size and appropriate size of the
VENUS, If you see the that from distance of 110" INCH distance and if you see
the dot of Venus means your eye is adapted to see VENUS transit without optical
aids. (always use proper filters to protect your eyes) else you need some
magnification ranging from 1.5 to 3.

You can starch the diagram so as you can make it 100 mm disk size and VENUS 3mm
size but you need to go 4 times away = 11 Meter, as you increased size by 4.

The Link below has a Picture which is also adjusted accordingly for 13" monitor
size - 25mm size of SUN disk and appropriate size of VENUS. so you can try there
too.
