    Can somebody tell if its even rare?

    Not rare, but it is a beautiful spiral galaxy. It has a name #NGC 0157 *NGC0157 and is closer than many of the fuzzies that we look at. You can tell because it has good resolution and the stars are small.

    dusty #spiral starforming limbs ETG 339 references and a few notes:

    2005MNRAS.357..361S Re:NGC 0157 NGC 157. A prominent thick spiral structure is seen in both the submillimetre maps for this partially inclined galaxy (i= 49^deg^). A high contrast between the arm and inter-arm regions is seen. The peaks of the submillimetre maps are centred on (or very near to) dark lanes within the grand spiral arms of the optical image.

    2003AJ....126..742H Re:NGC 0157 The morphological classification as determined by us is indicated in parentheses next to the galaxy name, with our "chaotic circumnuclear dust" (C) category now not including those galaxies with obvious dust lanes (DL). Where the classification has already been made by Martini et al. (2003), we indicate this with "-mp." . 3.1. NGC 157: Spectacular Nuclear Dust Lane (DL) Figure 19 (top). Images: NGC 157 is a spectacular example of why infrared observations are sometimes vital for studying the centers of spiral galaxies. In the STIS image the nucleus is completely obscured by a V-shaped dust lane, and yet in the NICMOS image the nucleus appears smooth and unobscured. The presence of the dust lane meant that we were not able to acquire the true nucleus for the spectroscopy. Hence, the spectra quality is classified as "missed" in Table 1.

    2002ApJS..143...73E Re:NGC 0157 NGC 157.---Sbc (type example---see Fig. 3f ): No apparent bar. Grand-design spiral pattern. Oval bulge with the arms beginning at the ends of the bulge minor axis. SW arm initially linear, then begins to wind, and bifurcate as it crosses the disk major axis. Arm fades after only 180deg. NE arm is very wide to NE and appears to wrap a full turn before it fades away. The optical types for this galaxy are SAB(rs)bc: (RC3), Sc(s)II--III (CAG), and SBbc (OSU). It is thus a rare example of a galaxy that appears optically barred, but unbarred in the near-IR. What appears to be a bar in the optical looks much more like the result of projection in the near-IR.
