NGC 5139 - I was looking for a target to image while I was waiting for my main target to rise and the Omega Centauri cluster looked pretty good. Got 2 hours of total data on it with RGB filters and thought I would process it as a practice run. Pretty happy with the results and also pretty amazed with what else is in the image. Plenty of faint galaxies in the background as well and I have always been curious on how deep I am to see. The results are pretty cool. Have a look at the second image for the annotated image with principal galaxy catalogue numbers. Omega Centauri is 17,000 light years away. Also in the image, for those targets that I could find distances for are:NGC5206 - 10 Mlyrs (million lightyears)PGC46502 - 91.3 MlyrsPGC47003 - 114 MlyrsPGC46583 - 161 MlyrsPCG47092 - 197.8 MlyrsPGC500733 - 705.28 MlyrsPGC512512 - 968.7 MlyrsPGC509172 - 1.06 Blyrs (Billion lightyears) Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a
globular cluster in the
constellation of
Centaurus that was first identified as a non-stellar object by
Edmond Halley in 1677. Located at a distance of 17,090
light-years (5,240
parsecs), it is the largest-known globular cluster in the
Milky Way at a diameter of roughly 150 light-years.
[10] It is estimated to contain approximately 10 million stars, and a total mass equivalent to 4 million
solar masses,
[11] making it the most massive-known globular cluster in the Milky Way.Omega Centauri is very different from most other galactic globular clusters to the extent that it is thought to have originated as the core remnant of a disrupted
dwarf galaxy.
