Sonyme Posted June 16, 2021 Share Posted June 16, 2021 I don't know much about solar photography so forgive my ignorance. Is this a single shot image or stacked? Could you tell me a little more about the processing? Gary Quote Link to comment Share on other sites More sharing options...
Smerral Posted June 16, 2021 Author Share Posted June 16, 2021 Hi Gary, this is a stacked image. I find that with Calcium images it is better to stack fewer. So these are the best 20 out of 200 using Autostakkert. The original image , like all narrowband images, is in mono (captured by a mono cam). The colouring was done in Photoshop, as was sharpening (using wavelets in Astra image plugin but you could use Registax) and a little contrast enhancement.
