Corwin's Notes

===== NGC 7471 is lost. Seen only once by Frank Muller with the Leander McCormick 26-inch refractor, there is nothing within several degrees of its position that comes close to matching his description, accurately copied into the NGC (Muller made the magnitude 15.8, and the size 0.2 arcmin). There is no sketch. Wolfgang chose a 19th magnitude galaxy 3+ arcmin southeast of the nominal position. That, however, is too faint, has no 10th magnitude stars 20 seconds preceding, and has a different position angle; it cannot be the object that Muller saw. I have not checked large digit errors (10 degrees, 1 hour, etc). Someone with more time and patience than I might uncover Muller's nebula that way. ----- Retirement has its benefits. I've done this checking for large digit errors and have turned up a candidate galaxy at 23 08 55.0 -22 52 55, five minutes of time east of the nominal position. The stars are 30 seconds west rather than 20, and there is a line of fainter, though still obvious, stars just 10 seconds west. Finally, there are two stars to the south and southeast, bright enough that I would have expected Muller to mention them had he seen the galaxy with the Leander McCormick 26-inch refractor. So, this object is a candidate only, and has settled into the position table with a question mark.
