Well, as my tax quids went towards the EU up to 2020 or so or whenever final brexit happened in practice and the EU shoves money into ESA and EUCLID, and my tax quids go towards ESA coz UK is a member thereof, all from the outset of the project, and as some of of my tax quids will also have gone towards Manchester Uni funding, I can always pretend that this is a big telescope I have got a share in, that is I've spent some cash towards EUCLID so it is also MECLID (probably a massive sum total of nearly 10p over the years...).
If you dig around the ESA EUCLID site you'll find that the FITS files are available for download. They come in a giant TAR file of 7.2 Gb size, so they take some downloading, and expand out to massive gzip files (or is it the other way around) and they themselves extract out to even more massive files, comprising FITS image files or around 4.8 Gb in size.
Now, it took me a while to get a FITS viewer that'd work with files that big. Granted Aladin did but with large files most zoom scales are sampled and only the full zoom gives the full image detail, which was incredible quality! However, not covering much area. As well as hanging up when trying to save it out to other formats and not allowing to save anything but the current view.
Also, I've never really tried to process any fits files before, my skills at such appear to be somewhere between less than zero and null.
So why am I banging on about it? Well, because hidden on the ESA EUCLID site are other object that have been released, about five or so, as well as the colour enhanced versions released the other day to the public. It took me a while to get anywhere with them, and my results are far worse than the originals, but the files were so big installing things like siril or what have you did nothing as the files were too immense, but I did get to save them to PNG files which were only very big, manged to load those in GIMP, tweaked and cropped 'em a bit in GIMP and then saved 'em as JPG and cropped and shrunk them until they'd fit inside the 500 kb limit here.
They're way more abysmal than the originals, but it'll give you an idea of what other objects are available if someone can manage to play with single FITS files of nigh on 5Gb. Incidentally, they are all VIS images (the optical to just NIR camera), NIR camera images in Y, J and H bands are also available but are much smaller and grainier and attempting to merge a VIS, Y and J as blue, green and red just looked totally abysmal with hue issues so I ignore that.
ESA and the EUCLID consortium get the credit, these are public release images. I'll leave them up a while before ditching them.
First, and not at all done well as the images are where orginally far more details on the screen but so narrow field zoomed in not worth screen capturing, on screen I was able to get the overexposed bright bits not overexposed and showing gently arcuate and near linear wisps whilst B30 and B31 looked good and crisp and dark whilst surround by nebulosity, but not able to get both in the image at that scale at the same time.

Second, the dwarf (satellite?) galaxy Holmberg II where I can't manage to get a better darkness without loosing the stars.

and on the next post NGC 2403, which looked far better at one point and then I went and lost the best settings trying to get it better still!
