Description

Surprisingly, only a WFPC2 version of this galaxy is <a href="http://hubblesite.org/newscenter/archive/releases/1996/21/image/b/" rel="nofollow">featured</a> on the Hubble sites. This is a combination of WFC3 and ACS data. It's not quite as deep as the WFPC2 observations but it's still a lovely set of data.

Red: hst_11570_23_wfc3_uvis_f814w_sci Green: hst_11570_23_wfc3_uvis_f350lp_sci Blue: HST_10802_86_ACS_WFC_F555W_sci

Various other data was (were?) used to fill in the chip gap. I did something strange this time, too. I rotated the diffraction spikes for the blue channel so that they would match with the other two channels. There were only three stars this time so it wasn't a big deal to do. I don't know about other people but one of the more obscure things which please me are the subtle, rainbow-like spectrums visible in some diffraction spikes.

North is NOT up. It is 58° clockwise from up.
