Description

NGC 6992, Eastern Veil

DSW 14.5 RCOS, STX-16803, AO

The surface brightness of this object is very low, making it a difficult target for visual examination in a small amateur telescope.

The Veil is believed to be the remnants of a supernova explosion some 80,000 to 50,000 years ago. The filaments suggest they are thin shock fronts seen edge-on. The surface brightness of this object is very low, making it a difficult target for visual examination in a small amateur telescope. But the dust and gas radiate most prominently in the OIII band. Visual observations through an OIII filter show wispy nebulosity, even in an 8" telescope. In the X-ray spectrum, the Veil is the biggest and brightest object observed from earth.

This false color rendition, of course, which differs from the standard ones (e.g., HST). No rendition is better than any other.
