After a discussion on Strömgren spheres and all the little H-alpha bubbles in the Triangulum galaxy over at Asterisk, I became interested in processing some of the archived data on NGC 604, which is actually an enormous complex of hydrogen clouds in M33 (Triangulum Galaxy).
I confess that the data is somewhat Franken’ed together because I wanted a slightly wider view of the object and slightly less of those awkward polygons of missing data. There are still a few blank triangles but I think the result is ok despite them.
Red: hst_05773_03_wfpc2_f656n_wf_sci + hst_05237_02_wfpc2_f656n_wf_sci
Green: hst_05237_02_wfpc2_f555w_wf_sci + hst_05773_03_wfpc2_f547m_wf_sci
Blue: hst_05237_02_wfpc2_f336w_wf_sci + hst_05773_03_wfpc2_f502n_wf_sci
North is NOT up. It’s 73° clockwise from up.
Hubble data is public domain, but I put a lot of work into combining it into beautiful color images. The minimal credit line should read: NASA / ESA / J. Schmidt
