NGC/IC Project Restoration Effort

===== NGC 5570 is probably NGC 5519, found at its correct position by d'A in April 1865. WH's description of his first observation of the object reads, "vF, forming an arch with 3 sts." NGC 5519 indeed forms an arch with two stars west and southwest, and a third is superposed on the galaxy. WH's observation puts N5570 21m 15s p, 0d 34' s of 31 Bootis. This is 6 minutes of time off the position of N5519. I think that the "21m" is a transcription error and should read "27m." In that case, the RA as well as the Dec and the description would match N5519. Steve Gottlieb has found that WH has a second observation of this on 12 May 1793. That one puts it 1m 53s preceding and 1 deg 24 arcmin north of HD 124929, considerably closer to NGC 5519. WH's description reads, "2 vS stars with nebulosity suspected between them." He apparently did not include this in his list of nebulae because he "suspected" the nebulosity. Curiously, WH has another very similar observation of NGC 5575 = NGC 5578 in the same sweep. See those numbers for the second short story.
