30 October 2013 AR Details

The image below is made of two images – one taken with a stack of JPEG and one with a stack of RAW frames.  Bizibilder’s normal way of imaging the Sun is with a stack of JPEG images (usually around the best 50 from 130 or so – the rest being discarded), however, JPEG does show “compression artifacts” and RAW should give a better result.  It certainly does – and you should be able to see the difference here (two second “blink” between images) – especially the detail within the general surface granulation on the Sun.
