Sadr Region in Ha with 200mm Lens

The region around Sadr (γ Cygni), center star in the cross Cygnus, is filled with gas and dust making it a prime location for emission nebulae and camera lenses. Sadr is the bright star in the lower left central portion of the image.  The Sadr Region (a.k.a. the Butterfly Nebula or the Gamma Cygni Nebula, or IC 1318) is the diffuse emission nebula surrounding Sadr and is approximately 4900 light-years away.  From what I gather it includes the Butterfly but also the surrounding area above Sadr.  Other objects in this image include the Crescent Nebula (NGC 6888) - bright nebula off to the right, M29 (NGC 6913 a.k.a. Cooling Tower) - open cluster on the lower central portion of the image, IC 1311 - open cluster with lots of nebulosity in the upper central portion, NGC 6910 - open cluster just left of Sadr.  NGC 4996 - an ope star cluster below the Crescent Nebula, and NGC 6914 - an Ha region on the left portion of the image.  Numerous other Lynds Dark Nebula (LDN) and Bright Nebula (LBN) are scattered throughout this region.  I really like the lower portion in the Butterfly area where the gas and dust swirl around as well as the region near the crescent.

This image was taken over two evenings using the Canon T3i/600D and 200mm lens with the Astronomic Ha-Clip filter mounted on the iOptron SkyGuider Pro.  This is my travel set up so I can easily take it on an airplane or set it up while I am imaging something else with my telescope.  The next best thing to creating a mosaic with a telescope.  Shooting normal color images with thie set up is easy because you can use live view for find and focusing.  However, using the Ha filter was tough as you have to turn all the settings up and do a minimum of 5-second exposures to find anything and then focus.  I plan to add color if we get a clear night without the moon as this was taken when the moon was high up.
