Excellent Fernando, time very well spent

Not that much exposure really, considering how well that outer curtain is showing

Thanks so much Rolph.
However, I should say that I almost quit this project. The first three days I did not have even one reasonable frame. Over the other days the seeing improved gradually, so that I managed to collect these 25 frames with less than 20% change in FWHM, what is not great but was the possible. Also these 25 frames presented a good transparency.
Doing the frame accounting, I captured 72 frames of each channel to use 25 frames in a project that lasted 9 days.
A very interesting effect of the seeing I noted, was when I got a sharp image, but without any outer halo. In other situation, I had a not so sharp image, but with lots of outer nebulosity, what means more transparency.
Too crazy seeing relationships.

nice one Fernando, with this detail you really imagine how the material ejected while the star was spinning.
