IC 2144 and IC 2948 - the running chicken nebulae in a
widefield view |
|
Short object description
Southeast of the blue, bright star Lambda Centauri
lies the open star cluster and emission nebula IC 2944/2948, which is about
6500 light years away from Earth and covers almost 4 times the area of the full
moon in the sky. The true extension is therefore about 75 light years.
Furthermore this wide angle image shows the nebula areas IC 2872, RCW 61 and
Ced 116.
In the English language
area the nebula complex has the nickname "running chicken", whereby it is
difficult to see a running chicken in the nebula form. In the inner part of the
nebula are the well known Thackeray globules, which we have already recorded
with longer focal length at Rooisand Observatory. IC 2944 was discovered in
1905 by the American astronomer Royal Harwood Frost, who was also the
discoverer of the asteroid Cava. |

The region of IC 2944/2048
is also shown in a
narrow-band image, taken with AstroDon filters with a half-width of 3 nm,
which show the Thackeray globules in particularly high contrast ...
