Description

Hi folks,

This is the last image I took in 2020 on a cold December night and I'm very happy with it. Considering the time I've spent outside by frozen temperature to take lights, darks, flats and bias (I redo bias every 2 months), it was better to bring out a decent final image !!! ;-) Despite the winter sky is known to be the best period, I would cheer having much more "human-friendly temperature" while shooting :-P
So, what to say more about the Rosette Nebula? I'm a bit lazy today so feel free to google it for more information, hahaha :-)
Stay healthy and all the best for you in 2021!
Christophe
