An alternate method for viewing Mercury consists of observing the Earth having a telescope all through daylight hrs when disorders are distinct, Preferably when it really is at its finest elongation. This allows the Earth to generally be located simply, regardless if utilizing telescopes with eight cm (three.1 in) apertures. On the other hand, great care need to be taken to obstruct the Sun from sight due to the Serious risk for eye injury.
