AR12818-21 in Ha - 26th April

ar12820-ha-ds90-290mm-bw This active region has really developed over 24 hours, spawing a number of new spots, and AR designations from NOAA too. I was racing high cloud for this image which I took after work. Stacking 64 out of 4000 images gave a usable result, even if the image had to be chewed a bit in ImPPG. Taken with the Coronado DS90 and the ZWO290mm camera which i'm very much liking as a system that appears to have a real synergy. Looking forward to using it more in the weeks ahead as we move forward in the new solar cycle.
