Here's a look at the central group of galaxies in the chain, taken with my Skywatcher Esprit 120ED. This was a challenging shoot due to my 2-month old EQ6R-Pro which ceased to function and had to use my much older 11-year old Atlas mount. The tracking suffered a bit but compensated with much more exposures (24.5 hours). Anyway, hope you like and thanks for looking!

Very nice! I have the same scope and camera! I have no idea how you are able to tame the star colors with 5 minute exposures as mine are washed out with 3. Do you use 0 gain?

I'm not sure.. but it's probably just a matter of processing. Shoot me an example so I can see what you mean

You're essentially getting the same data I am with the same gear. It looks great, just needs some careful processing of the color. I use Pixinsight's Automatic Background extractor once I've combined the RGB channels and tweak it from there.

Amazing work! I’ve got a new setup on its way, including the Wsprit 120. I’m curious to know if you used a reducer/flattener, an electronic auto focuser, or any other accessories. Thanks so much and clear skies to you!

I appreciate all your comments, thanks! :)

Here's my astrobin link to the image, with all the gear used. For this shot just the stock flattener that comes with the esprit along with the awesome Sesto Senso 2 Focuser.

Good luck with the Esprit! It's a killer scope with a truly fantastic, versatile focal length. I also highly recommend the Starizona Apex-L which is excellent and will give you 546mm @ f/4.5
