Perseus galaxy cluster (Abell 426) from Paris
I imaged it with my 8" f/4 newtonian astrograph and an ASI183mm on an AP900 CP4 mount from my light-polluted backyard in Paris' suburbs (Bortle 7-8). The luminance (10 hours overall) was taken over two nights during the rare cloud breaks we had the last month. The RGB data is from last year (with an ASI1600mm).
I invite you to have a look at the full-res and uncropped image:
Here is also a link to the annotated luminance with many galaxies from the PGC catalog as well as quasars labelled by their redshift (the most distant has redshift z=2.9)http://www.astrosurf...9590e30a0d2.jpg
Thanks for looking and clear skies,
