As we peer through the window which is our own galaxy, we look through billions of stars in our own galaxy, across intergalactic space, to discover new galaxies camouflaged by our own galaxy's stars.  One such group is Stephan's Quintet (lower left of middle), a group of 5 galaxies in Pegasus discovered in 1877.  4 out of the 5 galaxies are 280 million light-years from earth and are interacting with each other (if you look closely at full resolution you can see the cores interacting with each other).  Since we are seeing what these galaxies looked like 280 million years ago, chances are they have already merged into one or more larger galaxies.  The blueish galaxy, NGC7320 is much closer to earth (39 million light-years) and not interacting with the other 4.  
To the right and up of center you will see the Deer Lick Galaxy group.  This group has 5 galaxies with NGC7331 being the biggest as well as the closest to earth, 30 million light-years away.  The other 4 being 300 million light years away. There is another interesting cluster of galaxies to the right of the Deer Lick group at NGC7345. This is a fascinating part of the sky that contains many galaxies, I encourage you to roam around at full resolution and see how many you can find.
The colors you are seeing are true, what you would see if your eyes were sensitive enough.  For example the blue tinted stars are 10 to 150 times as large as our Sun and blue to our eyes, because they are much hotter than our Sun.  Cooler stars than our Sun are red.
This image covers over 3 degrees in the night sky and the camera has 60 Megapixels at 1.4 arcsecond per pixel.  It reveals the beauty of the Universe from far away, and yet detail of the galaxies as you load the full resolution image.  A Deep Field image (to borrow nomenclature from Hubble).

Acquisition:
I captured this data using Red, Green, Blue and Luminance filters over 3 nights 9/21/2022, 9/23/2022 and 9/26/2022 at my Astronomy Club's dark sky property, San Diego Astronomy Association (SDAA) at Tierra Del Sol, Bortle 3 location.  I camped there overnight on all three nights.  Broad band images (full spectrum, RGB) of galaxies need to be acquired at a dark sky, otherwise the images will be swamped by light pollution and galaxy detail will be lacking.  
I took a total of 81 - 15 minute (20.25 hours) exposures of visible light (Red, Green, Blue, Luminance).

35 Exposures 15 minutes each, unguided, Luminance = 8.75 hours
17 Exposures 15 minutes each, unguided, Red = 4.25 hours
16 Exposures 15 minutes each, unguided, Green = 4.00 hours
13 Exposures 15 minutes each, unguided, Blue = 3.25 hours
Total Exposure 20.25 hours

I've added a plate solving algorithm from PixInsight which overlays the image and identifies the objects in the Star Catalogs.

All the NGC PGC objects identified in this image are galaxies.  Hover your cursor over one of the catalog objects and click on the object and the full resolution image will come up, you will be able to identify the galaxies.
