Notes: This magnificent Messier open cluster is almost as large as my field of view, somewhat lessening its photographic visual impact ... the very rich open cluster partially seen to the southwest (lower right) is NGC 2158.

According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of M 35 is 25 arc minutes.
