Description

I'm extremely exicited to present what is most likely the first deep color image (RGBHOO), of Fr 2-2 in Cetus.  Fr 2-2 is a very faint potential planetary nebula in the constellation Cetus. The object was discovered in 2006. It's listed in Dr David Frew's July 2008 Doctoral thesis (Planetary Nebula in the Solar Neighborhood: Statistics, Distance Scale and Luminosity Function) and the 2006 International Astronomical Union paper, (A Search for New Emission Nebula from the SHASSA and VTSS Surveys). Although it's listed as a potential Planetary Nebula, the literature also mentions it is also possible that this object, is instead, an ionized ISM nebula since it doesn't seem to have all the typical markers of a planetary nebula. The color RGBHOO image is composed of 2hrs of Red, Green and Blue exposures, 14.7hrs of Ha exposures and 15hrs of OIII exposures through 5nm filters. The area surrounding Fr 2-2 is very dusty with brighter patches off to the left of the nebula and fainter dust throughout the image. The bright star in the center of the nebula is HD 16686, a mag 9.17 AO spectral type star. The brighter part of the nebula is close to 830 arc seconds wide with fainter extensions out to 1108 arc seconds. Below are inverted Ha and OIII images along with continuum subtracted and starless Ha and OIII images showing the emission parts of the nebula.  The continuum subtracted and starless OIII image shows a very faint hint of OIII emission.

There are several fairly bright NGC galaxies in the upper right of the image along with many fainter PGC galaxies. The brightest of these is NGC 1024. These can be seen on the annotated image.

The image was captured over 4 months from 30 Aug 2022 to 26 Dec 2022

**UPDATE:  Since the publication of this image, it has been seen by researchers and Fr 2-2 has now been updated in the HASH planetary nebula database as most likely a ISM nebula http://202.189.117.101:8999/gpne/objectInfoPage.php?id=17477  This shows one example of how amateur data can help the professional astronomical community.**
