This is cropped from a wide field image I took in September, a total of 8 hours of exposure using a mono camera with RGB filters, the less-cropped version is here.

I live downtown in a big city with severe light pollution, I was convinced broad band astrophotography is nearly impossible in a big city like mine, but apparently, with modern technology (hardware and software) it is possible to gather enough light in one night and separate them from light pollution to create an acceptable deep sky image, although it won't be as detailed as the image taken under a dark sky, but it's somewhat doable with a reasonable budget.

Equipment:

- Scope: Celestron RASA 8

- Mount: Ioptron cem40

- Camera: ZWO ASI183mm pro

- Filter: Optolong 2'' LRGB filter set

- Guide scope: ZWO mini120mm

- Guide Camera: ZWO ASI224mc

Stacked and processed in Pixinsight.

More of my astrophotography works on Instagram.

I also have a small youtube channel featuring some of my astrophotography projects.

Are those orbiting each other or on a collision course?

Amazing photo when comparing it to a muti-billion dollar instrument photo!

The left galaxy is ~39 million light-years away, the rest four galaxies are far far away than the left one, about 300 million light-years away, two of them are clearly entangled.

NASA could have saved a fortune if they just hired you. Quite impressive.

I absolutely adore your full size photo. To think this was done in a city environment is unbelievable.

But more wonderful, is how your photos carry that 80s space vibe through into the photo. I cannot get enough of that, forgive me, ET esque style and I thank you for sharing this amazing picture. It's like the Universal logo from the good old days.

I apologize if something serious as space astronomy is taken by me as nostalgia pop culture but I honestly love the look you have captured. Much better than the JWST in my opinion. :)

If you have any more similar space pictures with lots of empty space please DM me! Thank you thank you

Thanks for the compliment!

I can't explain the 80s feel, but my image does have similar quality compared to the 60s big telescope's image, like this one, it was taken by 200" Hale telescope at Palomar observatory, 50 years ago!

I'm working on another JWST target NGC 628, 30 million light-years away, a really beautiful 2-arm spiral galaxy perfectly face to us, I'm gonna share it when it's done!
