I would like to know your thoughts on this strange nebula:

It's in the HOO palette. Could not find any information on this nebula.

Is it a supernova remnant, or a planetary nebula? What do you think at first glance?

I don't know exactly what is but if this is a planetary nebula so can you tell me its name coz i also didn't know but this absolutely looks fabulous.

I've just checked with astrometry.net. The stars are part of the Heart Nebula, but the image looks nothing like it!

RA: 02h 34m 29.620s DEC +61° 06' 10.368"

Is it a mouse mat?

CS, Tony.

I searched this image on google but there was only one thig I saw, Veil nebula. bro and when i searched to get exact completely exact image like this, I didn't find any. bro did you found a new nebula! bro just tell the exact coordinates of this nebula please bro.

At first glance this looks terribly artificial and strange, everything from the colors to the shape

Just as Tony I decided to check it with astrometry.net; https://nova.astrometry.net/user_images/9629947#annotated

Here's the annotated result:

Same result with Aladin lite centered on HD15851 (although we know it doesn't look anything like this already):

JPG decolorized:

So the real question (at least for me), @messierman3000, is what the purpose if this image is? Did you try a AI generative application on a star field and why would you attempt to pass it on as an unknown object?

I am having a hard time understanding what I'm looking at… Is that an illustration? Or is it actual photographic data? I've never seen anything like it. IF it is actual data, I wonder if the data was somehow heavily quantized? The fact that it is right where heart nebula should be, though, makes it even odder.

If this is actual photographic data…what is the bit depth?

It definitely doesn't look like any object I've ever encountered, so color me a bit skeptical.

This image looks like a copy - paste oil splash on a star field, using Photoshop. Looks too bad even for AI generated non-sense. Smelling like a bad joke trying to "test" astrophotographers on astrobin.

Interesting. It looks like the op’s image and your heart are 90 degrees out though. Look at the cluster of stars on the middle right. It’s definitely the same stars, but they need to be rotated.

i can see some of the same nebula structures in both.

Well, yes, they are 90 degrees apart. But I'd like to know what similar structures you find in the images. I can't find anything that implies that anything but the stars may be real here.

Ok, on the op's image, see the double stars at the top of "nebula"? Those two are on the left of the heart image. The top of the op's nebula lines up with the left of the heart you posted. the structure is actually very similar, it's just fuzzy, faint, and maybe in a different wavelength than the op's.

I think the poor guy just had a low flyby of a bird or something, then it froze.

Yes, the stars check out, but there's a lot missing in the image that OP posted. OP said that this was a HOO image, so where is Melotte 15 and the rest of the nebulosity? Here is a long integration containing this area; https://www.astrobin.com/full/vr75s8/B/# There's nothing there that point towards the OP's image being a real structure at all. Let alone any possibility of picking this up using Ha and Oiii filters without getting the rest of the nebulosity in the area.

I'm standing by that this is a fake image passed on as a real thing, perhaps posted solely to get the discussion we're having as someone suggested. Something only OP can clarify if he/she decides to respond. I for one find it odd to do so though, especially on this platform.

Alright, I'm starting to feel a bit guilty... So you guys want to know what the image is? What's the H-alpha and OIII?

Well, the H-alpha is snot, and the OIII is blood. I blew out bloody mucous onto a napkin because I was sick; you heard me right, and the snot nebula was called "absolutely fabulous"!

The coordinates were Right Ascension 1/4 inch to the left, and Declination, 2-3 inches up my nostril.

In Photoshop, I just cropped out the napkin, removed reflections from the snot, drastically modified colors (yellow to red, red to cyan), applied 1 black image and 1 gray image, and superimposed them onto the snot in different ways, so as to modify the structures of the snot, and the background of the image, and make it look more like an astro-photo, then I got a StarMask (stars image) from a past editing project, from the Heart nebula, and I added fake diffraction spikes, and then I superimposed that (screened it) onto the "starless image" (my snot), then I made the entire image a little bit blurry, so that little imperfections might not be easily seen, and did some further modifications in Camera Raw.

However many of you quickly caught me. @Bogdan Borz in particular, was more accurate more than any other, and I'm surprised about what he said, but still, no one alluded to the real nature of this object; and @andrea tasselli seemed like he didn't believe it at all; his name for this object made me laugh a lot.

The whole idea was to see how many people would fall for it right away, doubt it, or say it's totally fake. Was this experiment worth it? Well, I guess a lesson was learned; you cannot believe an astrophoto is real just because you see it, and plate-solving and reason are both necessary to know whether an astro-image is fake or not.

Some might laugh, some might be annoyed, but I just want to say this, I got the original idea from another Astrobinner:
("New discovery" actually coffee stains in this guy's kitchen)

And this motivated me more:
(Scientist takes a picture of a slice of chorizo and says it's Proxima Centauri)
https://www.cnn.com/2022/08/05/europe/scientist-space-image-chorizo-intl-scli-scn/index.html

I think a thread for this type of stuff is more fit for a place like CloudyNights.

Anyway, next time I talk about any nebula or DSO, just know I will never be joking in this way anymore.
