Notes: Huge, I expect it would be a fine sight in better conditions. It is evidently a face-on irregular spiral. From a prominent non-stellar core the most obvious arm curves away E, passing a foreground star. A second shorter, less apparent, arm heads N. I cannot make out separate arms to the S or W. This area has the appearance of an extended halo with an unusual concave edge in the SW.
