Description

Last night I could test again, and in H-Alpha the stars look better than in Luminance.
I guess the chromical abberation of the corrector is the cause of this.
Maybe I should buy a Televue VIP3010...

This is a single 1200s (20 minutes) integration, only a master dark was subtracted.

The next night, 5 integrations were added to improve noise.
