I have been fortunate and grateful for three days good weather so managed to image AR720 at the same time on three consecutive days. This sequence is the result and it shows how rapid the growth in this sunspot has been
Each image is just a single good frame from a short 15 sec avi from my Sony handycam. My stacked images seem to look unnatural. The avi was de-interlaced with avisynth / virtual dub and images given a levels adjustment slight unsharp mask in Gimp. The result convinces me that single frames at high shutter speed can give a better result.
The full disc was taken with a Canon A40 2 MP digicam at 1/1500 sec. The Canon just couldnt do as good a job as the handycam at high resolution.
Thanks for looking, cloudy weather again
so please keep posting AR720 images.
