Thanks Howard,

yes it made a lot of fun to pick all HII regions. I need at least around 2 hours for the rough sketch. The outer regions were only visible with 4mm AP (172x) as subtle glowing around the main structure - a little bit to bright in the sketch.

The faintest HII region was the stellar HII region [H76]-13 3,5' NW of the core. I missed the brighter [H76]-292 1,2' NE of the core, perhaps the background arm was to bright?

Look also after the galaxy 2MASXJ01365368+1542071 around 5,6' SE. NED and LEDA did not mentioned a magnitude, VizierR note 17,3bmag for the USNO-B1.0. Seems to fit with my observation, the galaxy is the same brightness like the brighter to middle bright HII knots within the galaxy.
