And here is mine no assigned colors by me.

Explanation: In one of the brightest parts of Milky Way lies a nebula where some of the oddest things occur. NGC 3372, known as the Great Nebula in Carina, is home to massive stars and changing nebulas. The Keyhole Nebula (NGC 3324), the bright structure just below the image center, houses several of these massive stars. The entire Carina Nebula, captured here, spans over 300 light years and lies about 7,500 light-years away in the constellation of Carina. Eta Carinae, the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that much of the Great Nebula in Carina has been a veritable supernova factory.

Yep…
“ Though even these photos are an enhanced version, since most celestial objects, such as nebulas, emit colors that are too faint for human eyes to make out. It takes a telescope, letting light build up in its CCD over time, to see the rich hues in Hubble photos.
And for other Hubble images, scientists assign colors to the filters that don’t correspond to what that light would look like to human eyes. They do this when using light from infrared and ultraviolet filters, since those wavelength ranges have no natural colors, or when combining light from slightly different shades of the same color.
“Creating color images out of the original black-and-white exposures is equal parts art and science,” NASA said.
For example, Hubble photographed the Cat’s Eye Nebula through three narrow wavelengths of red light that correspond to radiation from hydrogen atoms, oxygen atoms, and nitrogen ions (nitrogen atoms with one electron removed). In that case, they assigned red, blue and green colors to the filters and combined them to highlight the subtle differences. In real life, those wavelengths of light would be hard to distinguish for humans.

Yup.
Nice work. I have had a couple-few scopes over the decades and still have a few, but only dabbled in photography back in the days of film. I never put the time/money/effort into it to do deep sky stuff, but got a few nice planetary images. What kind of scope/mount are you using?
And here is mine no assigned colors by me.
The scope is probably 20 years old now, but still kicking after several repairs.
Anyway I should have just said that I like your photo in post #5 because all a person seems to get these days is the enhanced colorized ones using filters. Ones done using unmixed light gives me a more realistic feeling of outer space.

So for one, Hubble image has dimmed the near stars to deemphasize them.
I will say processing this stuff out of a really dark raw frames, and then trying to squeeze as much existing data out of it as possible is addicting. I work with what I have. This is a low budget affair...lol
Nice!
Who else sees the giant alien’s face?
They sure did. So it doesn’t take away from what their main target or subject is.
I noted the refraction spikes that were added in the other image, when completed it was obvious they over-powered, so to speak, the main subject. Some people like to add them, others don’t. But I keep all the original data/copies and it can be reprocessed leaving them out if desired.
Very impressive!
This image was 137 combined images, all the same exposure time of 60 seconds per exposure. I had to dump about 10 percent of them due to issues. I’d like to get about 300x1 minute images and combine that data. The more time spent imaging a real low light object the better. On clear nights I once wanted to target 3 or 4 objects a night, but found it just didn’t work out. No bueno. Now it’s focus on one target per night and absorb as much data as possible.
Thanks!
Artistry and science combined. In a few million years the Orion star cluster will be the brightest object in the sky, besides the sun and moon, due to the nebula currently there. It is a giant star forming region of colorful interstellar gas, and not too far away either by galactic standards.
You bet, it’s a stellar nursery and it’s real close.
Well it’s fine with binoculars, but as always, more enhanced views of it are nice.
Binoculars? Agree. Sometimes wide field is the best with open clusters, Milky Way etc., especially at dark sites.
You no doubt have some good equipment. My equipment is a slightly expensive 16x80 binoculars and a monopod and a folding chair. But I’ve been an astronomy enthusiast just about all my life, and I don’t have a back yard. Just a porch. So I sort of envy an ability to expand further.
