Criterion for Sighting the Crescent

Criterion for Sighting the Crescent
33. Is the sighting of the new crescent through binoculars, telescope, retrieving the data saved in a computer or the like sufficient?

A: The sighting of the new crescent with an instrument does not differ from usual sighting and it is valid. The standard is to say it has been seen. Therefore, sighting with the naked eye, with glasses, and through telescope are ruled the same. However, computerized photographing of the crescent moon which cannot be clearly categorized as sighting is problematic.
