This particular nebula whose coordinates are RA/DE (2000) 20hr 16min 57sec/+41. 49" 17.6', is not designated in any catalog I can find. The only reference is from the Simbad Astronomical Database as 'LDN 892' using the above celestial coordinates. To the imager it appears as triangle.

This image consists of 24 x 600sec. subs for a total of 4hrs.
