Summary
[edit]DescriptionAbell 1367 with Manually added Galaxy distances.jpg |
English: This Galaxy cluster in "Leo's Tail" at 350 Million Lightyears is shown here with Annotated PGC Galaxy Numbers with Their calculated Distances. (It is a big image, so best viewed at full resolution, click here for the Flickr full res: <a href="https://www.flickr.com/photos/kees-scherer/39833714680/sizes/o/">www.flickr.com/photos/kees-scherer/39833714680/sizes/o/</a>)
Image dates: 5,6,16,17,18 april 2018. Esprit 100 refractor/ QHY16200 CCD @ -20C 2 x Drizzle was used in APP (and a crop) Platesolved in PI and Annotated with PGC catalog. The 290 PGC Galaxy numbers where used to find the "Modz" (Cosmological distance modulus) in the Hyperleda database: <a href="http://atlas.obs-hp.fr/hyperleda/" rel="nofollow">atlas.obs-hp.fr/hyperleda/</a> The modz value was converted to Megaparsecs: <a href="https://en.wikipedia.org/wiki/Distance_modulus" rel="nofollow">en.wikipedia.org/wiki/Distance_modulus</a> And finally converted to Million Lightyears and added with the PI Procees, Painting, Annotation Tool. Only after adding the distances it becomes clear that there are 3 distinct "levels", first the 350 Million lightyears for Abell 1367 members, second a group at around 1500 Million LJ and third a group at around 2500 Million LJ. And many, many more at greater distances (not in the PGC catalogue) |
