FDs in Ha and Ca II K plus a few shots in Ha of the main proms around the limb. Additionally I took a few images in sequence in order to make a mosaic of the chromosphere in the region around the main filament. There's also a closer view of this region. These close views and proms were captured on the 150mm/DS Lunt 35 mod.

Re: Some sunny views in Ha and Ca II K 10th April 2021
You got a nice run of images Stu, I saw you had some decent weather yesterday. I was hoping for a full suite of images yesterday too but the weather just closed in on me and it was game over...
