NGC 1535 is the name of the brightest planetary nebula in the constellation Eridanus . The distance from NGC 1535 is given as 5000 to 6000 light years, the true diameter a little more than one light year .
It was discovered on February 1, 1785 by the German-British astronomer Wilhelm Herschel .
Visual observation
The brightness of NGC 1535 is sufficient for observation in a small telescope from an aperture of around 70 mm, but there you will only find a faint, stellar object. In a larger telescope with an aperture of around 6 inches or more, NGC 1535 is already very noticeable. The 12-mag central star is a bit difficult to observe, even with a 10-inch aperture; successful observation requires correspondingly good seeing .
