The ISS with BEAM and the Ring Nebula

Scroll down to content

Ten days ago the ISS astronauts inflated the BEAM module, a new concept that may help (a lot) with the construction of large space stations, Mars and Moon exploration modules.

On the night of May 28 the ISS had a pass over my location at over 65 degrees above the horizon. On the same day the BEAM module was inflated, so I was hoping for good seeing to get a good resolution of this module. Together with my wife I’ve prepared the 8 inch scope and imaged the pass. Unfortunately, the seeing was bad, and thus the images are of poor quality. Nevertheless, some structural details are easily observed.

A comparison from the same session with the visible planets, again under the same poor conditions. Not the large apparent size of the ISS:


And another image, this time a test-shot from May 31, using the 14 inch scope and the ASI 174MM camera at the focal plane (F/5) with an UV/IR cut filter, and no coma corrector. 274 frames, each a 1 second exposure, were used for the image. A lot of light pollution and bad seeing, but details inside this wonderful nebula are discernible.
