Glimpsed NGC 188 from my urban sky.

Limiting magnitude about 3.5 or 4. This was no easy task. I've been trying to view for quite awhile. I used an 8" Intelliscope dob, but the COL alone was not enough. I also used a 30mm 80* eyepiece and Uranometria 2000 (newly acquired 1st ed) to identify the field. Once the spot was pinpointed (and the atlas was essential for this) I was able to up the magnification and some of the cluster stars (mag 12+) became faintly visible with averted vision. I should add that I had an 8" SCT flexible dew shield on the end of the scope as a glare shroud (also kept dew off secondary) and a black observers cloth over my head and eyepiece to block off glare from streetlights and the like.
Those in an urban environment with larger scopes should do even better. I'm just happy it was do-able with the 8".
