Prominences and chromosphere time-lapse from December

[Sergio Alessandrelli]

Hi to all

I've posted two "new" time lapse from the last December 20221201. First is on prominences in H-Alpha taken with a 0.5A filter, the second in CaK, 2.4A. For H-Alpha I used a FLT132 (4X telecentric + full aperture ERF), for CaK a Zeiss 63/840 (2X Celestron Ultima barlow). File are bit big, so I post the link to Astrobin.
Changing on the chromosphere in CaK are not so fast, but something is visible.

Bye
