Sharpless 2-27 in Ophiuchus
Sharpless 2-27 is very large nebula centered around Zeta Ophiuchi. Very difficult to photograph due to its size and brightness, it is over twenty Moon diameters wide and very faint. Film and detectors well equipped for Hydrogen-Alpha (Ha) imaging reveal it best. I consider it one of the greatest objects in the Milky Way.
Located on the Milky Way's border in Southern Ophiuchus and partially overlapping into northern Scorpius. This is notable in the image with dense stars seen on the lower left and sparse stars seen on the upper right, away from the galaxy center.
From the observatory logbook, April 3, 2008. "Got up at 2:50 A.M. Clear Skies. Sky Quality Meter (SQM) 21.67. Magnitude limit approx 7.0, Milky Way rising. Photographed Scorpius and Ophiuchus regions. Temperature: 28 degrees F."
"Sharpless 2-27 in Ophiuchus 165mm @ f/4 3:36-4:06 AM EST"
The photograph of Sharpless 2-27 was my first with this lens. The 165 portrait lens works beautifully for these wide-field "close-ups".

Thank you Luc. I try to visualize the size of this nebula when I look to Ophiuchus. It's pretty darn big.

Very nice one, nice stars too, and at 165mm, you're right, this is a very large nebula, amazing, continues your good work!

Thanks Steve and Mark. These large, faint objects are just fantastic as well as a challenge to image.
Steve, we went to Eastport for the 4th a few years ago. It is the place to be. Look me up if your in the area.

Nice looking shot James. I grew up in Maine, been to Eastport for the 4th of July once as a kid. We go to Belfast every summer for half a week then go to my parents camp in Oxford county for the other half. I look forward to more of your images.
