Great images again, Frédéric! Regarding the continuum image, could you elaborate on the data (exposure time, N/D, ...).

Best wishes,
laura

thanks, Frédérik. Concluding from your data, is the transmisson of the HaT11 ERF a just a bit lower than that of the ND3.8 baader filter?

Excellent set of images, Frederic. The level of detail in the continuum is extraordinary.
