Although the Horsehead Nebula is difficult to see, the amazing fact that it can be taken without any specialize equipment or software. The photo was take using EF85mm f/1.8 lens on a Canon 5D and and a tripod. The exposure was 10 seconds a 3200 ISO. The Gimp was used to bring up the contrast a little and a free noise reduction software was use on the photo without writing. The Horsehead Nebula I can not view using my 10inch (250mm) Dobsonian telescope. That is why I am so amazed with the results from this camera.
