Ha Full Disk 14th April

Our sun is looking great at the moment with all this activity that has come round the eastern limb, by the weekend it will be more mid disk and in great position for imaging.  This shot was taken with the DS40 at 560mm focal length with the DMK31 camera.  These etalons definitely produce better images when the temperature is warmer and the pressure is higher - oh the physics of etalons!
