Description

Here is a mix of my first image of M81 & 82 (back in march) that looked like "something", but far from an achievement, I decided to add some subs this summer in south of France and last night at home.

Data :

> Old image : 5x 40", 23x 60", 12x 90", 3x 150" and 3x 165" @ ...different iso settings (old ways, I tell you! ) ;

> New sessions : Ha 4 x 840'' + Bb 8 x 300'' @ 3200 iso

The color treatment of the first version was awkward so I'm not quite happy with this mix ;

And for the new subs, at this time of the year, the target wouldn't rise much above 30°... I expect to add more "quality subs" later this autumn and get rid of the old one for brand new, more "pristine" rendition... on this page.
