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: www.flickr.com/photos/kees-scherer/39833714680/sizes/o/)

 

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: atlas.obs-hp.fr/hyperleda/

 

The modz value was converted to Megaparsecs: en.wikipedia.org/wiki/Distance_modulus

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)
