This image is a 40-panel mosaic of the constellation Cygnus captured with a Canon 100mm lens attached to an Atik 460ex CCD camera using the Geoptik Canon-to-T-thread adapter. To 50 hours of exposure with the 100mm lens I also added high-resolution data for several of the deep-sky objects, bring the total exposure time to about 75 hours.

The entire cross of Cygnus is here, stretching from Deneb in the upper center of the photo to Albireo in the extreme lower right. The North America and Pelican nebulas are, of course, prominent, as is the less famous but equally large Sharpless 119 to the left of North America. To the right of the large dark "Coal Sack" region is the bright nebulosity surrounding the star Sadr. Some distance away from the Sadr complex in the 1-o'clock direction is the small Propeller Nebula; to Sadr's lower right are the Crescent Nebula followed by the Tulip Nebula. At the bottom center is the Veil Nebula. The small but very bright blob in the upper left of the image is the Cocoon Nebula with large open cluster M39 to its right.

In addition to the higher-resolution version linked to above, here is an even higher-resolution image in which about 60 of the interesting deep-sky objects are labeled. There are many more than this; I just labeled the ones that I thought were visually prominent or interesting for some other reason.
