Hi all,
It was late morning when the sky cleared of lingering mist and by that time things were warming up making the conditions tricky for capturing quality close views of our Sun.
Anyhow here's a montage of the main proms around the limb and a view of AR12842.

I'm hoping for an early start tomorrow and better conditions.
Thanks for looking.
Stu.

Re: Sun in Ha 16th July 2021
Excellent! thanks for the views Stuart, it looks like you and I were under the only cloud in the whole of England this morning. I was hoping for a view this morning, it is OK to set up between 8am and a quick capture by 9.30am as no one notices. By 11am, no chance. Hopefully tomorrow I can get first light with the Solar Spectrum

Excellent presentation Stu.
Alexandra is this a new kind of filter or something?
