About this object

FR 2-10 is a very faint ionized interstellar medium (ISM) nebula near the star HD 134358 in the constellation Libra. There is not much to see here in regards to bright nebula, although very faint clouds of ionized gas are visible if you look really hard just above the star near center and also in other areas around the image. Clicking on the image above will open a full resolution image where some of the faint gas is easier to see. FR 2-10 is also cataloged as PNG 353.8+43.4. Here is a link to this object in the HASH planetary nebula database: My guess is that this object was once thought to be a possible planetary nebula and was later found to be just an area of ionized gas. The star near center (HD 134358) is an orange sub giant that is 7th magnitude and lies some 262 light years distant. It is 4 times as large as the the sun and 14% cooler. Peppered though out the image are many faint background PGC galaxies and many uncatalogued galaxies and a few galaxy clusters. The majority of the PGC galaxies can be seen plotted on this annotated image.
The image was taken from early April into early June 2022 with my 6" refractor and covers an area of sky of approximately 1x2 degrees. The image is a combination of data taken through RGB, Ha and OIII filters. The very faint ionized gas was only visible in Ha filtered data.
