Fr 2-24

Frew 2-24 is a rarely photographed emission nebula or planetary nebula in the southern constellation of Puppis.  It was discovered in the SHASSA Survey (Southern H-a Sky Survey Atlas) by Frew et al. (MNRAS, Vol 431, Issue 1, May 2013, p 226) as a possible planetary nebula.   Almost no information is available for it.  As shown in my image, it resides in background H-a emission.  It has a complex, partial arc structure with a gap and thin outer filament.  This image results from 12.5 hours of 30 minute H-a + [NII] exposures, and about 3.5 hours of RGB data for star colors.  6.5 hours of 3 nm OIII data were also taken but did not show any emission near the H-a arc to the limit of this equipment. This object will remain a mystery until additional research is conducted.
