I am soliciting advice on where to image the largest concentration of galaxies, preferably for wide-field (3.5 degrees or so) views.  Think of this as a poor-man's Hubble Deep Field. 

 

I use a GT 81 with a ZWO ASI2600 MC PRO.

The Hercules cluster is a cracker. Abell 2151. Lots of cool spirals in it too which makes for a good picture.

I'm not an astrophotographer by any stretch but I think the largest, and most easy to image would be the Virgo-Coma cluster of galaxies. I think that Markarian's chain should fit in a 3.5 degree FOV.

Definitely agree with this!  I had a ton of fun on this one, also trying to make my own "Skywatcher Deep Field."  :)

Took this image of Markarian's Chain earlier this year - about 5 x 3.5 degrees.

Clusters of galaxies come in all angular ~sizes~ dependent mostly or range. There are plenty of Abell Clusters that are nicely captured in a 1o field using a largish scope. For a 3.5o field the selection is more limited... to just a few. But if you enjoy good dark skies... can point the telescope in any random direction and have myriad detectable galaxies in the field. e.g. Here's a picture I took with my old 12-inch scope onto film back in the mid 1980's. I was intending to only image NGC 7331 and Stephan's little group of five there... but you can see other generally-ignored galaxies sprinkled all over the place. I got into the habit of examining every deep sky shot for galaxies... and always finding them. To the point where I conclude that it would be challenging to shoot a random pointing and not find galaxies!

 

Worth considering: >>> Instead of always shooting the same few dozen targets that all the other guys are forever imaging, pick something that is ignored... or even a random field that shows nothing notable in the atlases. I guarantee you will not be disappointed!

 

Q: "Would you like to see my picture of Niagara Falls?"

A: "Ummm... No."

Q: "Would you like to see Chris's picture of a substantial water fall that we stumbled across while hiking along Reynold's gull last week?"

A: "Really, I never knew... Yes!"    Tom

The greatest concentrations, as in number of galaxies per area, are probably found for one of the many Abell galaxy clusters, such as the Hercules cluster (Abell 2151), the Leo cluster (A1367), Coma cluster (A1656) or the Corona Borealis cluster (A2065). However, these are typically very distant (the latter at some 1billion ly) and so the galaxies are small and the cluster will not fill your entire field of view. Somewhat nearer (at 250Mly) is the enormous Perseus-Pisces Supercluster, one of the largest structures in the observable universe and extending some 40 degrees of the sky: you will need several fields to cover the whole thing.

As a start, you may try centering your image around NGC 708.

In the southern hemisphere we have the Dorado cluster.

If you zoom in to full size and view at the scale of the pixels, you can distinguish faint and small galaxies from stars.  The field is just 0.6 degrees wide and I think there are over 1000 galaxies in there.

Try Abell 426 or Pegasus I galaxy cluster.
