Around Abell 262, a galaxy cluster in Andromeda



Abell 262 is a cluster of galaxies that are part of the Pisces-Perseus supercluster and approximately 205-250 million light years distant.  I cannot find good information on how many member galaxies are included in this cluster.  I set out to work on some deep sky object imaging fundamentals.  I started imaging the bubble nebula (seen here)  Then I moved to another part of the sky and I'm not sure why I did it but found all these tiny galaxies using my star charts.  In awe I took a photo and found as many galaxies as stars.  Flashforward weeks later and I finally get around to learning more about this fascinating part of the sky.  I imaged a part of the sky near, but not including Abell 262.  Here is the full view of a mosaic of two separate areas.  All told I estimate that there should be near 76 or so galaxies in this one mosaic image of 2 sub images.  Some  have distance/redshift measurements some do not!  Read on for some mind blowing facts!



And the glorious 15 MegaPixel view (Scrolling required)

Here is a labeled view, where each red area/dot is a galaxy!



------------------------------------------------------------

Now let's take a look at some close ups of interest. 


In this subarea, there is approximately 30 galaxies.  Use this mouse over for details.

Along the top of the full image is my favorite is this area, which includes the most distant object I've observed to date.


This one struck me with the different sizes, shapes and types of galaxies all in one area.  This field covers 10 galaxies in an area of about 13.5 arc minutes wide.  Of all of these galaxies I think I love the barred spiral on the right and the tiny spiral above the A in Abell on the bottom title bar.

Here is the mouseover to help find them.

Now for some mind blowing details....
-------------------------------------------------------------------------------

This happenstance image with some fact finding of my own includes the furthest object I've yet observed.  Let's see how I came to this conclusion.

My references to imaged fields are plate solved and overlaid in Cartes Du Ciel via the solved fits wcs header info.  Then using the CdC PGC catalogs I can reference the v (velocity - http://leda.univ-lyon1.fr/leda/param/v.html) information, typically expressed in km/s and measured via 'Compilation of cz (radial velocity) measurements' (http://leda.univ-lyon1.fr/leda/rawcat/a110.html)

Convert velocity measurements into redshift (z - speed of light in vacuum):

Convert z to distance in light years:
http://www.convert-me.com/en/convert/length/auredshift.html

For example our 'fastest receeding' or furtherst galaxy, PGC197602, is measured at 35444 +/- 36 (http://leda.univ-lyon1.fr/ledacat.cgi?o=PGC197602%20)

35444 km/s = 0.1182 (z)
0.1182 = 1,628,000,000 LY or 1.628 BILLION Light Years away from Earth.

You could compare this to the age of the Universe's expansion, 13.8 Billion years (http://en.wikipedia.org/wiki/Age_of_the_universe) and claim it to be 11.79% of the most distant objects yet known.  Think about that.  From the comfort of my home I can use tools to witness the photons leaving millions of distant suns at a time 1,628,000,000 years ago!  Well, plus or minus 1,654,000 years that is!


Concidentially nearby to this galaxy is, PGC: 3626780, which has no measured magnitude or redshift values. Not that I'm going to purchase a spectrometer but if anyone has one that they think would help measure these objects I'll willingly give it a try.

About Me

My photo

Loving husband, proud father, computer geek, astro freak, music lover, sports nut and general fun-loving guy

I think I'm the kind of person who doesn't like strong opinions.  It doesn't matter if I agree with your opinion or not, it's not factual, it never will be 100% factual and I don't care for it.  That's probably why I hate politics.

I've always loved facts, provable facts of nature and things concerning science.  

Over time, I found that most facts are mostly reference and it was the creation of and discovery of new things that intrigued me.

"A good friend once told me you are our memory
without them we equal nothing
And all I can see is the place I wanna be
Suddenly my life was so free
Leaves at my feet, blown to the ground
their echoes are reaching my ears
Nights coming fast, suns going down" - A7x
