Active Region 12781 has kept observers busy. Despite the Sun being so low, seeing was excellent on Saturday morning and I managed to catch this one just after midday.

At last! A solar defect! Nice.
I've been showing friends (we had a local family in our bubble) the sun with my LX90 and camera (*with appropriate filtration!) over the summer and found zilch.
Nice, I like calcium views.

Very good Roberto
How did you get the calcium line?
I assume its a filter?
