Detailed Information:
M029 is an open cluster in the constellation Cygnus which has the Trumpler classification of III 3 p n. The fourth entry "n" denoted surrounding nebulosity. These nebulae are DWB33 on the upper left & LBN224 on the right. These identifications are based upon the annotations on Bernhard Hubl's beautiful wide field image -

This object was observed and cataloged by Messier on 29 July 1764. It is located 2 degrees south-southeast of Gamma Cygni (the central star in the cross of Cygnus). To visual observers there are typically only about a dozen 8th- 9th magnitude stars. It is somewhat obscured by the nebulae that overlay it in the eyepiece. My image only begins to capture these nebular, but for a better and wider view I refer you to the image link above.
