Description

A 2-panel mosaic of the dust cloud region of the Iris Nebula in Cepheus, at about 4k by 9k resolution. Contains: lbn468, vdb141, iris nebula, cr 427, sh 2-136, ldn 1174, ldn 1170, ldn 1147, ldn 1158, ldn 1167, ldn 1152, ldn 1148, ldn 1172, ldn 1173, ldn 1155.

Panel-1 387 subs; panel-2 360 subs.

My posting of about a week ago of this region[1] was shot at 71mm f/4 (FL 350mm). I wanted to compare that result to imaging on the 11 inch RASA, 279mm F/2.2 (FL 620mm), in order to better resolve the Ghost Nebula on the left, and finer features within the Iris.

I invested more time in setting the dimmer dust off against the star field in the rendering of this version.
