Context paragraphs:
Francis Preserved Leavenworth: Francis Preserved Leavenworth (born September 3, 1858 in Mount Vernon, Indiana; died November 12, 1928; a.k.a. "Frank Leavenworth") was an American astronomer.  He discovered many New General Catalogue objects together with Frank Muller and Ormond Stone.  They used a telescope with a 66-cm aperture at the Leander McCormick Observatory at the University of Virginia in Charlottesville, Virginia.

NGC 130: NGC 130, a lenticular galaxy, was discovered on November 4, 1850 by Bindon Stoney, the very same day he discovered NGC 126 and 127.  This galaxy belongs in the NGC 128 group of galaxies.

NGC 375: NGC 375 is an elliptical galaxy located in the constellation Pisces.  It was discovered on September 12, 1784 by William Herschel.  It was described by Dreyer as "pretty faint, small, round, brighter middle."  Along with galaxies NGC 379, NGC 380, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 375 forms a galaxy cluster called Arp 331.

NGC 385: NGC 385 is a lenticular galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "pretty faint, pretty small, round, northeastern of 2." , the other being NGC 384.  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 386, NGC 387 and NGC 388, NGC 385 forms a galaxy cluster called Arp 331.

NGC 1553: NGC 1553 is a prototypical lenticular galaxy in the constellation Dorado.  It is the second brightest member of the Dorado Group of galaxies.  British astronomer John Herschel discovered NGC 1553 on December 5, 1834 using an 18.7 inch reflector.

NGC 127: NGC 127 a.k.a "The Emma Rostron Star" is a lenticular galaxy that was discovered on November 4, 1850 by Bindon Stoney, the very same day he discovered NGC 126 and 130

NGC 369: NGC 369 is a spiral galaxy located in the constellation Cetus.  It was discovered on October 9, 1885 by Francis Leavenworth.  It was described by Dreyer as "very faint, very small, round, gradually brighter middle."

NGC 380: NGC 380 is an elliptical galaxy located in the constellation Pisces.  It was discovered on September 12, 1784 by William Herschel.  It was described by Dreyer as "pretty faint, small, round, suddenly brighter middle."  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 380 forms a galaxy cluster called Arp 331.

NGC 384: NGC 384 is an elliptical galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "pretty faint, pretty small, southwestern of 2." , the other being NGC 385.  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 384 forms a galaxy cluster called Arp 331.

NGC 126: NGC 126 is a lenticular galaxy that was discovered on November 4, 1850 by Bindon Stoney, the very same day he discovered NGC 127 and 130.
