Black Hole Cygnus X-1

Where is Cygnus X-1? Cygnus X-1 is a black hole in constellation Swan. As it is a black hole it can't be seen. But we know it's near star HDE226868. I tried to find this star a couple of weeks ago but this failed due to setting issues and bad transparency. Yesterday I tried it again using Stellarium and with succes.
Setting: Nikon D7500 with TLAPO80/480 f/6, mini guidescope and guiding camera ZWO224MC, ISO400, 4x360s exposure time. Software used: Stellarium, PHD2 and ATP to control the camera. Pictures stacked using APP and final eding with CS4 and DeNoise AI.
