Rick,
Megastar shows NGC 7133 as a reflection nebula, 9'.5x6'.8, 20' south and one
degree west of the open cluster NGC 7142. NGC 7129, 2'.7 in diameter, is
shown another 15' west of NGC 7133 and described as a "cluster + nebula."
Perhaps, you observed NGC 7133?
Regarding NGC 7142, I observed this on August 17. Under 82X magnification in
my 10-inch, this open cluster revealed 16 members embedded within an
unresolved glow, 5' in diameter. PPM 23179 was visible 8' due north. Megastar
shows the cluster nearly centered on GSC 4274:1845 however, my sketch shows
the cluster immediately to the south of the GSC star.
Regards,
Bill Ferris
