If yesterday morning I tried, with no success, a full aperture shot of the Vixen VMC260L with the intention of immortalizing the granulation, during my lunch break I dedicated myself to our star in the h-alpha line.
The short free time available, made me lean towards mounting the etalon directly on the 120 ED, equipped with a 104 mm frontal ERF and etalon borrowed from the good Lunt LS50T Ha with his B600 blocking filter.
I used the ASI 178 MM after a Televue barlow brought to about 1.4x.
This caused me heavy Newton rings that I managed to eliminate through the miraculous flats of Firecapture (which didn't always give me joy, on the contrary).
The results leave me largely satisfied, perhaps for the first time since I have taken the Sun in this line of the spectrum.

Superb pictures.
I do not look at the sky with the eyes of an astronomer, but of a person looking for the beauty of nature.

Hello to everyone!
Many thanks for choosing one of these images for the SPOD, it really surprised me!
I have to reply to some questions some of you asked me since my last post in this section about the used equipment, I will reply very soon, maybe in a proper topic.
Yesterday afternoon I made again a take of the two main zones, in worsen seeing conditions
Here there are the changes of the regions.
I am also happy for the repetition of the results for the flat by Firecapture.
