ASTRO: A fistful of galaxies

With apologies to Clint Eastwood....

The full resolution version (33.1Mpixel) has a lot of galaxies visible.
This is 58 x 15 minutes of unfiltered light: AP155EDF f/7 with 4" field
flattener and FLI Proline PL39000M monochrome.

14.5 hours total exposure

You certainly have a bunch of those little guys. Including one on my
to-do list, MAPS-NGP O_134_0070142. It's the odd two arm spiral at the
top edge near the upper right corner. If it's redshift is correct then
it's a bit over 1.5 billion light-years away. If it is then it is one
huge galaxy to show so much detail even at your image scale. The "star"
at the end of its lower arm (well just above the end) is at the same red
shift so may be what drew its arms so far out. They are part of a
cluster centered 2 minutes NE where there's a bright core galaxy that
anchors the cluster, MaxBCG J209.15044+55.19236. It has 12 members at
1.65 billion light years average red shift. The difference is likely
just orbital velocity differences. If so then the spiral I'm interested
in is likely a bit further than its red shift would indicate.

You beat me to it!

14.5 hours is one heck of a lot of time! Explains the smooth look to
M101. You've got a lot more patience than I do!

Gives one a feeling for the emptiness of space.
They really are islands in a vast ocean.

mostly regions of nothing punctuated by regions of immense mass

Richard,

that's a great field, looks very crisp even in full resolution. And depths
is very good too, in spite of the low QE.

well the depth thing is compensated by taking 15 minute subs instead of 5
minute ones....
