The Butterfly Nebula – IC1318

A bright gas cloud with complex and intricate details. The dark central dust lane resembles a butterfly with the bright ionized gases on either side acting its wings.

Seeing was exceptionally good with sub-2.0″ frames. This allowed some high resolution data to be captured and processed here at 0.7″/pixel. At full resolution we can see many areas of interest with globules that are probably the early stages of star formation.

The native data was over 60 million pixels captured with the QHY600 in high gain mode with gain=56. The capture resolution was 0.46″/pixel later down sampled.

The CDK14 was operating at f/4.75 with the dedicated focal reducer.
