Corwin's Notes
=====
NGC 7748. Only the star (SAO 20818) is here. JH says, "About a * 8m is a
very extensive space which I am certain is affected with nebulosity." He saw
this on only one night, so the nebulosity may well have been a transient
feature of some sort (thin cloud? aurora?).
The magnitude of the star becomes "7" in the NGC; GC follows JH of course, in
making it "8". I suspect that Dreyer followed a later list with updated
photometry. The modern magnitudes are V = 7.15 and B = 7.18 (from Simbad,
May 2016).
