Explanation: About 70,000 light-years across, NGC 247 is a spiral galaxy smaller than our Milky Way. Measured to be only 11 million light-years distant it is nearby though. Tilted nearly edge-on as seen from our perspective, it dominates this telescopic field of view toward the southern constellation Cetus. The pronounced void on one side of the galaxy's disk recalls for some its popular name, the Needle's Eye galaxy. Many background galaxies are visible in this sharp galaxy portrait, including the remarkable string of four galaxies just below and left of NGC 247 known as Burbidge's Chain. Burbidge's Chain galaxies are about 300 million light-years distant. NGC 247 itself is part of the Sculptor Group of galaxies along with shiny spiral NGC 253.

Great photo.
From optic or radio telescope source?
The web site of the “acquisition source” shows an optical telescope so I assume that is what it was.
Wow.
I want to be a rapper and I want to be known as NGC 24/7! And my entourage will simply be known as the Friends. Look out y’all! NGC 24/7 and Friends comin’ through!
NGC stands for Non Galactic Character. So I’d rather be one of the friends.
Is it the Hubble Space telescope? or is there another in space. Atmosphere makes it difficult to depend upon earth based telescopes.
Space based is sent by RF means back through our atmosphere.
I’ve been to Goldstone and to the VLA sight for radio telescopes. No part of that is optic.
I got the tour on the VLA sight when only 3 dishes were operational. Chief engineer gave me the tour. It was quite impressive technology. Especially interesting was the IF wave guide, it looked like a 2-1/2” ferrite tube with 1/4 wave length wall thickness. Inside was a spun copper wire lining to carry the signal. That was long long ago. At the time, they were trying to use cryogenic cooling on the front end of the receiver to keep the noise level down. Then they came along with GASFET’s that worked without super cooling. That was in the Early 1980’s. Don’t remember the exact year, it was before 1985. I moved back to Texas in 1986.
I love those types of sights. Have been a ham radio op for 49 years. Had some great friends while I was in NM.
One of the first galaxies I found with my first telescope. It’s well placed and my eyes were much better back then.
Add in NGC 253, NGC 55, and NGC 300 and you have the next group out from the Milky Way
