Please allow me to set the record straight on the designations of these objects:

The guide is available as a (large) pdf here.
The Hubble designation applies to only the two IC nebulae. Struve & Elvey at McDonald Observatory used Gamma Cassiopeiae as a guidestar for their slit-spectrography survey; they did note the "fan shaped nebulae" in the vicinity and as for so many of their other entries, they describe a region. Cederblad (4)'s designations A & B apply to the IC nebulae, but he too noted more nebulosity. So did Gaze & Shajn with their addition of Simeis 111. Three of their papers include description for the nebulae. Sharpless and Lynds (both two entries) and Van den Bergh noted a significantly larger region.
There's only a single entry in my log and it's only for the brighter southeastern nebula IC63. October 2017, 14" SCT @ 110x / 45', unfiltered:
A part of the SE nebula IC63 is visible, the NW nebula IC59 is not visible. The part of IC63 that is visible, is a WSW-ENE elongated part. To the east thereof, with AV, a faint, slightly fanning out part is subtly visible, at the limit of visibility without AV. On the northern side the nebula ends quite suddenly on a line from SW to NE.
Is just over 1/2 FoV to the ENE of the star Gamma Cassiopeiae.
I wonder what aperture it would take to tease out the faintest parts..!
