IC 1537, also known as NGC 55, is a Magellanic type barred spiral galaxy, seen edge on, in the constellation Sculptor. It lies at a distance of 6,500,000 light-years from Earth. It is a neighbor galaxy to NGC 300, and the two may be a gravitationally bound pair. The two are some of the closest galaxies to our own Local Group. Other than that, I couldn't find much more information about this particular object.
This is data acquired by DSW-Chile with the TOA-150/FLI ML16200, total acquisition time was 16.7 hours (10 minute LRGB subs and 30 minute Ha subs). When I first looked at the data I thought, this just looks like an indistinct blob. But as I processed it, there's actually a lot of structures hidden inside the "blob". There's a bunch of Ha regions and dust lanes visible, if you zoom in. I tried to just blend enough Ha data in to accentuate the Ha regions without turning the entire galaxy red.
Anyway, hope ya like it!
Very nice image of an intriguing galaxy Tom. Actually, IC 1537 is not a designation for the galaxy itself. Rather, it is for some star forming regions in the eastern part of the galaxy's disk (right side) that do stand out well in your image. The galaxy was discovered in 1826 by James Dunlop, while the internal structure designated as IC 1537 is credited to Lewis Swift in 1897. Below is a link to larger scale images of the field of this internal feature of NGC 55. Again, well done.
