Corwin's Notes

=====

NGC 7158 is a triple star.  It is precisely identified by Muller's note "* 9.5 
PA = 40 deg, distance = 2.8 arcmin."  Both Bigourdan and Howe found the object
0.6 minutes following a typically poor Leander McCormick position, and there 
it still is on the sky today.

Steve's Notes

=====

NGC 7158

18" (8/31/11): At 220x this triple star appears as a soft or nebulous "star" that won't focus sharply.  There is a strong impression, though, of a slightly fainter companion attached on the west side. I could easily see how the merged image of this triple could be taken as a possible nebula (described as a "vF neb[ulous] star").  At 285x it appears to be a double star, though the separation is quite small and the stars were not cleanly resolved in only fair seeing.
