Description

Dear astronomers,

Nights are short these days and still not the best of weather, but our patience was rewarded with 3 (more or less) clear nights.

It was the first test with the Falcon Rotator and the filter wheel/mono cam - now our setup is complete 
Although one could think about a better mount

We were able to get to quite some detail and gained more experience in LRGB processing - so please zoom in.

Besides the visibility of the dust cloud from which the galaxy is forming itself, we're especially impressed by the wealth of (in this image small) galaxies that are diplayed - it' simply incredible how beautiful and diverse our universe is!

Unfortunately, the galaxies aren't recognized by Astrobin's astronometry - so I played around with Pixinsight and added some catalogs in the Annotation Script. 
Now most of the galaxies have a name (s. revision B) so I started to look for a database with galaxy information and found HyperLeda (http://atlas.obs-hp.fr/hyperleda/).
There, I could get information about PGC2191787 (the object on the very right of the image circled in green/mint).
The DB states that the distance modulus for this galaxy is µ=38.55 ± 0.03.
If I'm not mistaking, the formula to get the distance in parsec from the distance modulus is d=10^(µ/5+1)=10^8.71≈513 Million parsecs.
As one parsecs equals about 3.26 lightyears, the objects distance is about d=1.67 billion lightyears.
I've found this fomula for the error on wikipedia: Delta d≈0.461* d * Delta µ≈23 million lightyears, which is only 0.023 billion lightyears.

JUST IMAGINE THAT - we've imaged an object 1.67 ±  0.02 billion lightyears away out of our backyard with a 10" Newtonian !!!

Unfortunately, I don't know where to get information on e.g., N5PM002041. 
Are you aware of any database for these kinds of objects?

Hope you like the results and CS
Timo
