Perfect, thanks!

Perfectly understood. And seems that the new video do not use Ha Continuum Subtraction. The older technique is still valid, or is something newer now?

Interesting, thanks Adam! Looks right to me. I noticed that when shooting Ha of NGC 6769 and NGC 5426, two very distant galaxies (190 and 130 million light years away) in Obstech. Seems to me I can’t get the isolated Ha emission of them

Thanks! For aesthetic astrophotography, what would be the visual consequences of a uncompensated gain integration?

Thanks!

Thanks! That makes sense to me. And what about eccentricity? Should we keep only, say, < 0.48 frames, or better integrate them all too ?
