As one with an interest in astounding facts I hope someone can answer this
question. Hubble's field of view for one particular observation was
equated
with the area of a dime at 75 feet, how many of those areas would there be
in the total sky, northern and southern hemispheres? Incidentally, Hubble
identified at least 1,500 galaxies in that observation.


It's not necessarily the picture you were thinking of but the Hubble Ultra
Deep Field* image
has a field size of 3 arc minutes square**, which is comparable to a dime at
about 67 feet

Thus, you would need about 16,500,000 images to cover the sky***.
There are claimed to be about 10,000 individual galaxies in the HUDF image.

*** HUDF required 1million seconds exposure time in total, hence it would
take appx 530,000 years to image the whole sky to that level of quality.
