10-inch reflector, and spending four hours in my attempt to see galaxy NGC 4236, of which the first three were unsuccessful.  However, during the forth hour, at well past 1:00 AM EDT, could glimpse an extremely faint, elongated NNW-SSE oriented blur of light as shown in my sketch.  The galaxy appeared featureless due to the extreme low surface brightness, and visible only intermittently with averted vision. 

There is a distinctive half-circle of five stars, NNE of the galaxy which works well to assist in determining the exact location of this very faint galaxy, or better said, an extremely faint galaxy. 

Sky conditions were poor with a NELM of 4.9, which is about normal for springtime in the foothills of North Carolina.  

On the previous night, under the same conditions, using a 6-inch reflector, the galaxy was invisible, despite spending two hours in my search.
