Galaxy

h: "pretty faint, small, round, very suddenly much brighter in the middle to a star of 12th magnitude." His next observation reads: "Not very faint, round, suddenly a little brighter in the middle, 15 arcsec across. The first of three." This galaxy lies in the half-degree grouping of NGC 3347, 3354 & 3358.

Hartung notes: "In an interesting field sprinkled with many stars are three nebulae, of which NGC 3347 is the first . . the first and third are ellipticalm and the second is small, faint and nearly round. 15cm shows only the two ellipses, and rather dimly."

The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads S,EL,BM,ODIFARMS.
