Sh2-101 is a hydrogen emission nebula around 6000 lightyears distant, resembling the shape of a tulip photographically. The plethora of stars in the image is the result of the Milky Way running through it.
In this HSO image, hydrogen has been mapped to red, sulphur to green and oxygen to blue. It is the result of 6 hours of narrowband data capture from Horsham, over three evenings in August 2024. A ZWO ASI2600MM Pro camera was used, through an 8-inch Teleskop-Service Ritchey-Chretien Cassegrain reflector.
