Description

IC1318B, the Butterfly Nebula is an interesting target because it is composed of both - Ha and O3 in a very mixed way. In the middle the dark nebula LDN 889, which separates the two "wings".

The final image was composed of one night of UHC subs and one night of O3 subs, taken with the ASI2600MC on the RASA11 (July 3 and July 4), Gain 56 Offset 10.

Processing in PixInsight, GraXpert, RCastro and Photoshop.

The stars were processed separately and opimized for real color and size.
