Yes, you can. It's ~9 mag, and not far from eta Cygni. Link1 (http://imagine.gsfc.nasa.gov/YBA/cyg-X1-mass/cygX1-more.html), link2 (http://www.jfmto.pwp.blueyonder.co.uk/cygnus-xone.htm).

If you look through your telescope near eta cygni, there is a ninth magnitude blue star that will look unremarkable in your telescope.

Here's a field of view showing it.

edit, I see nereid got the research done before me.

I hope that we will ever go to this star with its black hole to see and explore this star and (especially) the black hole of course. And is it free of danger to get (very) close to that hot blue star and the black hole? Is it warm nearby the star itself? I really hope that a manned or unmanned mission to Cygnus X1 will take place in the future. Will it ever happen? Can you answer this questions? Thank you.

The "X" in the name is because this object of a major producer of X-rays in our sky. It also gives off lots of other ionizing radiation in very big quantities. The star-companion to the black hole is very luminous all by itself. With our current technologies, I don't think it would be possible to get a craft close enough to the black hole to be able to image it with more than one pixel in a telescopic camera.

As noted in previous suggestions about missions, such a mission would cost trillions of dollars to launch and would get no results for hundreds of thousands of years.

Too much clouds at this moment ,no Cygnus X 1 this night. Tomorrow i hope for clear skies. And is it true that it is a dense stararea near its location?

Cygnus X-1 is over 8000 light years away. The Voyager probes have been traveling for about 30 years and they are only a few light hours out. We're not going there, or any where else outside the Solar System, any time in the forseeable future (centuries).
