Observations on Some of the Nebulae

By the Earl of Rosse, F.R.S. &c

The Earl of Rosse presents five sketches of well-known deep sky objects, made with "the speculum of three feet aperture".

He writes: "the sketches were originally made in the gallery of the telescope, and represent the objects placed as they appeared, not as they actually exist in space. I have copied them without alteration . The magnifying powers I have usually employed vary from 250 to 800; occasionally much higher powers have been useful; but to see everything described in this paper, a power of 600 with perfect definition is sufficient."

NGC 1952, Crab Nebula, Messier 1
