Lyra & Hercules constellations

Last night Lyra and Hercules were located near the zenith of my suburban sky, so I could make a series of 90 shots with 10 seconds of exposure each one. My equipment was the DSLR camera Canon EOS 450 (Rebel XTi). This image sequence is equivalent to a 15 minutes long single shot. After adding them with the shift-and-add technique, and substracting a dark frame (via Photoshop) that includes light pollution I got a final picture. I have aligned (using Nebulosity 2 software) the Stellarium map of the area and created an animated gif that switchs from the photo to the map continuously. It seems every star is located correctly where it should be 😉

Globular clusters M13 and M92 are there in the photo like 2 stars.
