Madam, - I would like to inform people, especially tourists planning to visit Dunsink Observatory, that it is located in Finglas, Dublin, and not Castleknock as was stated in the RTÉ programme Icons of Irish Science on Thursday, June 21st. It may not suit those who avoid this area of Dublin to accept that there is a place of such renown located here, but I am afraid this is a fact they must live with. - Yours, etc,
SEÁN DEEGAN, The Oaks, Newbridge, Co Kildare.
