This small but brighter nebula is overlooked my many imagers and for good reason, just next to it is SH2-49 or otherwise known as TheEagle Nebula which the outer parts of that object are seen here in the upper left area. But this small Sharpless offers a lot for the larger telescopes because it has nice structure around it. Those with a wider field of view can pick up a number of smaller objects around this one such as SH2-50 and SH2-53. The entire area responds best to the hydrogen-alpha filter and makes for a great black and white image with high contrast. But the nebula is bright enough to pick up well with the red filter so a standard RGB color image is not out of the question. I did not get anything much from the oxygen III filter so I don’t think this is a good one for narrowband color.

This nebula may be associated with the Scutum supershell in the Centaurus arm.

Avedisova places it in star formation region SFR 16.65-0.34 along with the molecular clouds SYCSW 164, SYCSW 164A and SRBY 52. She concludes that Sh 2-48 is ionised by the O8 V multiple star ADS 11285.

The newly discovered dense star cluster Kronberger 25 appears in the same direction as Sh 2-48, although a tentative distance estimate for this cluster of about 2000 parsecs suggests that it may be a foreground object.
