Notes: Stock 23 is also known as "Pazminos's cluster". Named by Walter Scott Houston for John Pazmino. Stock 23 is entwined in the faint bright nebula Sh2-202, which is located about 3 degrees due east of IC 1848. Had I known about the nebulosity when imaging this object, I would have doubled (at least) the exposure time.

According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of Stock 23 is 29 arc minutes
