Observing Notes

Harold Corwin

John Herschel's RA, which he says is for the double star on the northern edge of the cluster, is 27 seconds too small. This may be a wire error. In the sweep, he claims wire 1; if he actually used wire 2, then the RA would be 17 37 48 for J2000, just 10 seconds off.

Even if this is not John Herschel's mistake, there is no mistaking the cluster that he saw on the night of 7 June 1837.
