Low magnified flare


I was so exited about this flare that I tried many diferents magnification, this is the lowest, the sun disc it is more appreciable but the fine details were wiped out because the CCD sensor of the web cam have an array of 640*480 pixels to few to keep the Nyquist theory at its best, that it is because to many fine details fall into a single pixel , so the detector interpret these as a single feature, for a higher detailed image it was necessary to add a Barlow lens to increase the magnification, and “expand” the space between the detail distribute them on more pixel, check the next image at higher magnification
