Description

Here is a little more subs that I took in Spain and added on my previous attempt on Messier 101.

These are 11x 60sec subs @1600iso. It does bring a smoother look to it, a some more detail... but I'm far from satisfied with this ! Oh well, another cloudy night and time to experiment with PI and Ps ;-)

C VERSION : 2 more O-III subs of 360 sec each ; just used the core part to gain some more detail...
