Cassiopeia

The Queen

[Back to the Constellation Index]

Barry Ashforth took this picture of Cassiopeia on the 28th September 2006 at around 02:00 UT from the dark skies of North Wales.

An Iridium 53 flare and Cassiopeia imaged by Chris Newsome on the 16th November 2005.

The following picture is a wide field view of part of Cassiopeia. Stars and deep sky objects are annotated. The image was taken by Adrian Brown on the 9th November 2005. He used one of Chris Newsome's Pentax camera lenses, a 28mm at f/4, and an ATK-16HR camera with an Astronomik hydrogen-alpha CCD filter. Adrian took 3 x 30 minute exposures which were stacked in Maxim DL. The field of view is approximately 18 degrees x 13 degrees. The two big nebulas IC 1805 and IC 1848 are visible as well as the Double Cluster towards the bottom of the image. The right of the image shows the two main constellation stars epsilon and delta Cassiopeiae and also two small open clusters M103 and NGC 663. The open cluster Stock 2 is also visible. It has been called The Muscle Man on the web and if you turn your head on one side it does almost look like a figure of a stick man flexing his muscles!

Adrian Brown took the following picture of Cassiopeia and surroundings at 22:19 UT on the 12th August 2005. It shows a Perseid meteor at lower left. He used a Canon 300D camera with an 18mm focal length lens. The exposure time was 55 seconds at ISO 400.

Chris Newsome took the following picture of Cassiopeia on the 17th July 2004 from the Society's Flamsteed Observatory. He used a Minolta digital camera.
