Poster of the Sadr area in the constellation Cygnus, 75 x 50 cm | Oklop

In the middle of the summer Milky Way lies an area that glows red in long-exposure photographs due to vast clouds of gas. This poster of Sadr in the Swan shows that area around the bright star in the center of the constellation, in a size of 75 x 50 cm. Large enough to stand out on the wall.

You can find Sadr in the summer and early autumn high in the sky, as the middle star of the Swan’s cross. The nebulae around it cannot be seen with the naked eye. They only appear in photographs taken with a camera and often with a filter attached. narrowband imaging filters.

Measure the poster before buying a frame, because you need a large frame for this size. Hang it away from direct sunlight.

If you already shoot with a monochrome camera, then an H-alpha filter of 3 nm a filter that clearly shows this type of red gas clouds.
