| Description | The great telescope seen from the south-east, the stage of the first gallery slightly raised. The instrument's scale is demonstrated by groups of figures: to the right of the telescope as viewed, William Parsons, Earl of Rosse stands with two of his children; to the left of the instrument two gentlemen stand on a raised platform.
