A couple of solar prominences - morning of 28 October 2019

Before the clouds rolled in this morning I managed to capture these two.

It looks as if we are in for a roasting!

You've captured detail of the surface undulations on the Sun which I've never noticed before.  What telescope were you using?

Hi Noel

It was a 94mm f/7 scope with a 2.25x barlow and stopped down to 60mm aperture (size of front mounted etalon).
