Astrophotography: Over 200 galaxies in a single shot!

In this video I show the processing workflow I used on this image of NGC 891 and surrounding galaxies. There are over 200 galaxies in this image. The biggest one, NGC 891 is around 30 million light years from us. The "medium" sized galaxies are 200-300 million light years from us.
Equipment used for this shot:
Telescope: AT115EDT
Camera: ZWO ASI1600MM
Mount: SkyWatcher EQ6R Pro

Wow James, when you removed those stars and the galaxies showed... freaking amazing!!

[@DSOImager]

I knew that there were a lot of galaxies in this frame.. but I didn't know there were so many :)

[@Alan-vk6bk]

Fantastic image!!! Could spend hours looking through the background alone....

[@DSOImager]

Thanks Alan! Agreed! :)

[@FikMick7761]

Never disappointed by your work James, brilliant, keep it coming.

[@DSOImager]

Thank you! :)

I agree. Widefield galaxy shots are amazing. I say, often, 'stirring'. I'm late to this video, but I'm catching up. Great job James. Your talent is overdue for an APOD.

[@DSOImager]

Thanks Jason!

[@AZ4Runner]

WOW! great processing as always. I love the wide field galaxy stuff!

[@DSOImager]

Thanks Jason!

This is a fantastic image and I think galaxy cluster images are underrated. The number of galaxies here is astounding. Interestingly, at the end when you showed the starless and then star-full images, to me the galaxies really came to life when the stars appeared (which I was expecting to be the other way around).

[@DSOImager]

Thanks you Logan. CS!

[@SimonsAstro]

Excellent video James! I also like wide field galaxy images! NGC891 looks fantastic, nicely processed, I like your blending masks trick in pixelmath, a+b😀 I’ll be trying that out for sure! I’m a fan of Markarians Chain, in particular NGC 4435 & 4438 The Eyes! Can’t quite get my head around your little galaxies are 200 million plus light years away! Crazy, that’s why we love this hobby 👍 Clear skies

[@DSOImager]

Thank you Simon, I love these widefield galaxy shots. Markarians Chain is the one that got me started on these types of shots :)

[@avt_astro206]

Nice Image James!! Thats A splendid Star field!

[@DSOImager]

Thanks Avanteesh!

[@petesastrophotography]

Fantastic image James. I love a widefield galaxy shots as well. Tightly cropped images are great but you lose the sense of scale that a widefield shot provides.

[@DSOImager]

Thanks Pete! Exactly!

[@pascalnelson9034]

Great work, James. Did you post the finished image to astrobin or another place where we can see it in its full glory?

[@DSOImager]

Thanks! Yes.. I have it on astrobin. Link to my astrobin page is on my YT homepage. :)

@@DSOImager Thank you. I've got it now. Great images.
