DescriptionActive region 1520 displayed was one of the biggest sunspots in this solar cycle. Here it is imaged with a novel technique where three images made at slightly different wavelengths through a H-alpha filter are used as seperate RGB channels. This week I am blogging daily about this technique which anyone with a tunable solar H-alpha filter can use to make more colorful images of the Sun.
