Enhanced Triangulum

With nothing else to do with the endless cloudy skies, most of my astronomy has lately consisted of looking at other peoples’ images. My favorite part of this hobby is the creativity you can use while post processing your images. Some people prefer the blue-orange of the Hubble palette, others like more natural colors. Some like to keep the images subtle, and others like to stretch and enhance everything.

I took my data of the Triangulum Galaxy and played around with some of the post processing features in Siril. I used the local contrast enhancement, color-specific saturation, and an arcsinh stretch to really pull out all the features of the galaxy and make them easily noticeable. I finished with wavelet denoise and sharpening in GIMP.

Here was what I originally did with the data:

And here is the “enhanced” image:
