This image of the western Veil Nebula (Witch’s Broom) is centred on the 4th-magnitude star 52 Cygni. The star is a foreground object at 290 lightyears, while the nebula is 2400 lightyears distant.
In this HOO image, hydrogen has been mapped to red and oxygen to both green and blue. It is the result of almost 5 hours of Ha and OIII data capture from Horsham, over six evenings in July and August 2024. A ZWO ASI2600MM Pro camera was used, through an 8-inch Teleskop-Service Ritchey-Chretien reflector.
