Description

Hello friends.
Another Nebula (Sh2-261 Lower's Nebula) 😅😅, maybe the last one and I'll start with the galaxies 😬😬, I already had some data on this nebula collected at Christmas, now it's only available for a few hours and I wanted to finish it despite the moon Well next week we won't see the sun 🌧️🌧️. A little more difficult to handle, especially the background did not look very good this time, in my last image I could do without the noise reduction but here I applied the script (MureDenoise), it improved something, maybe the moon had something to do with it.
Greetings friends, take care of yourselves and enjoy.

Iñigo CS.
