16x80: using a UHC filter appears as a very large, irregular nebulous glow (about 2° diameter). Very faint but definite when compared without filter. Surrounds …2816 = 5.8/7.7 at 12" and a large, faint, scattered star group. Visible without a filter as an extremely large, hazy region surrounding …2816 and fainter stars. - Steve Gottlieb
17.5: The "Elephant's Trunk" (vdB 142/above) is an unusual cometary globule (associated with star formation) on the west side of the huge but faint HII complex, IC 1396. The most contrasty view was at 100x using a UHC filter, where a 15'x5' lane was evident, particularly by rocking the scope. The "tail" of the globule or elephant's "trunk" trails to the west and is weakly illuminated on the edges, particularly on the south side. A pretty double star is embedded in the lane which shows variations in width and opacity. - Steve Gottlieb
