CLICK IMAGE FOR the B&W Hydrogen Alpha image and 150% CROP


IC2944 is located in the constellation of Centaurus. It is a rich star forming region as can be seen by the extensive HII gases and dark nebula. Dark 'Bok globules' shown just above centre are small dark clouds made of gas  that are condensing to potentially form stars. These particular globules, Thackeray's globules, were named after the objects discovery. Giant shock waves of gas are stirred up from stellar winds from massive stars within. This object lies around 6500- 7000 light-years away

Notes/ Conditions

 Conditions- Average to good seeing and transparency when taking the Ha. .  This is a Hydrogen alpha composite to the RGB data. Trying to retain the small star sizes of the narrow band filter and match to the broad band RGB filters was obtained by reducing BB star sizes.
