I took the photo with the Sky-Watcher BK 909 AZ3 90/900 telescope using the Xiaomi Redmi Note 9 Pro phone. I took the photo 2 years ago so I don't remember what eyepiece I used but it was most likely 10mm

If you have GIMP, you can try using the G’MIC plugin (you will need to download and install it of course). It has a chromatic aberration filter that should reduce some of that blue glow. It will take some experimenting.
