AR12811 in Ha 21st March

ARs-Ha-colour It's nice to see activity ramping up on the sun, and the DS90 is a great setup for showing this activity, seen in this shot taken at f25 with the IMX174 camera. These new active regions have rounded the limb and are looking rather nice with plenty to see. I was fighting the seeing at this aperture, but lots of frames seemed to work. Just need the weather to improve a bit now we have moved into spring with the sun higher in the sky!
