Hi Marc, thanks for your more than kind comment.


Hi Jeremy,
Thank you for so kind comments. :thanx:


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. :confused2:

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