Astrophotographer discovers faint nebula in M33

[SwiMatt]

The astrophotographer Aleix Roig (@astrocatinfo on Instagram) discovered a very faint nebula in M33, thanks to his enormous commitment: 153h of exposure in OIII and Ha bands! 

Another amazing example of how amateur and professionals still work together in the field.

Should I go over to my image processing computer and examine my version of M33? 😁

Just highlights what's possible. I'd get extremely impatient imaging o3 for so long.

Fantastic capture and hats off to the commitment!

Trying to figure out roughly how long it would have taken me to capture 150 hours of imaging here in the UK (when the weather permitted).......I reckon about 20 years!
