The core of existential despair is contained within the fact that we only get to live once. Life comes and goes, each minute never to return. And the worst part is, none of our life gets to be lived in the Sombrero Galaxy.

That Galaxy would be cooler if it had RGB.

Those effects actually look like the natural lens and camera effects from Hubble, although some advanced sharpening filters appear to be applied. I believe "Real Color" color matching is typically used where out-of-spectrum data is used to enhance contrast and color to the visible spectrum data.

Notably there are several cameras on board that they tend to composite imagery from for these high resolution images. They provide different qualities to the final image for the real color image.

The current primary camera is the Wide Field Camera 3. This camera can operate in several modes.  It can use either fixed frequency filters, wide spectrum monochrome, or utilize a prism array to do either simple spectography of a single spot or imaging spectrography.

That's a lot of pixels

In fact it's a composite image, because the camera responsible is only 4000x4000 pixels.

Yes, they typically rapidly take many images switching out the filter set, and adjusting various camera parameters, then they composite them using real-color algorithm w/ contrast and sharpness enhancement.

And that star in the bottom-right of the image is just showing off

Surely it’s just a local star photobombing the galaxy…
