Quote:IC5217 9/17/2007 22:15 UT; Pickering 5, NELM 5.5, SQM 20.616" SCTDirect/averted blinker at 175X, nearly stellar. Wow, this is a tiny guy -- still nearly stellar at 375X (although it sticks around in direct vision at this magnification). UHC increases contrast but shrinks planetary. Something vaguely non-circular going on at 375X and 510X. 630X, an OIII filter and some motion (tapping the diagonal) adds averted vision ears somewhat like the Saturn nebula, but not nearly as well-defined. Axis of ears NNE-SSW, or perhaps NE-SW.
