This nebula has a lot of structure in it and is a great object for almost any size telescope. Larger telescopes can reveal the fine structure in the brighter area seen in the middle of the image. In contrast, the wide field of view offers a wide range of contrast between the brightest part of the nebula and the dark nebula such as Barnard 103 seen on the left side. SH2-59 is also just south of this object and can be captured as well with a very wide field of view. As bright as this object is the OIII filter did not do well. The hydrogen-alpha is the best filter to use with this object and if you take enough RGB then a great HA-RGB image can easily be created.

This large nebula is most often named GAL 025.4-00.2 or GAL 025.38-00.18 in the scientific literature. It has a bewildering number of different names in SIMBAD (not all cross-referenced).

It may be associated with the radio source W 42.

It is visible in infrared as the prominent bubble [CPA2006] N37 and appears to be ionised by an obscured O7 II giant.

The radio source W 42 has wildly varying distance estimates (from 13400 parsecs to 2200 parsecs). If the near estimate of 2200 parsecs (which is from a recent paper published in 2000) is accepted, then W 42 is likely part of the Sh 2-60 nebula. Infrared imagery in the same paper shows that W 42 is energised by a massive, dense and young OB star cluster embedded in an obscuring dust cloud in the bottom left part of this image.
