This image is the result of 30min of RGB data capture and 9h of narrowband imaging, through Hydrogen-alpha, Oxygen-III and Sulphur-II filters, over 3 evenings in February 2023. Hydrogen has been mapped to red and oxygen to blue.
A ZWO ASI2600MM Pro monochrome camera was used, through an 8-inch Teleskop-Service Ritchey-Chretien Cassegrain reflector, from Horsham.
