M29 (M29)
In Cygnus (Cyg) • Magnitude 7.1 • 7.0 arcminutes
Open the free AstroPlanner with M29 pre-selected, scored against your telescope, location, and the live cloud forecast.
A small, loose open cluster of about 50 stars embedded in one of the richest stretches of the Milky Way, in the heart of Cygnus. Dust between us and the cluster dims it by about 3 magnitudes — without that veil, it would be easily visible to the naked eye.

How to image M29
M29 sits in the constellation Cygnus at right ascension 20h 23m 53s and declination +38° 31' 12". To frame and integrate it well, AstroPlanner will compute the optimal moonless window for tonight from your location, the field-of-view fit against your sensor and focal length, the suggested total integration time given your aperture and sky Bortle class, and a cloud-aware schedule that drops it from the plan if your nearest cloud forecast spike overlaps the best altitude window.
