Helix Nebula (NGC7293, Narrowband)
The Helix Nebula (NGC 7293) is a planetary nebula created by a dying star shedding its outer dusty layers into space which in turn are hit by the star's core ultraviolet radiation. Planetary nebulae are actually the remains of stars that once looked a lot like our sun. The Helix Nebula is approximately 650 light years away in the constellation of Aquarius
I took this image over two sessions using my William Optics FLT91 APO refractor, 68III 1.0x flattener, ZWO ASI2600MC Pro colour camera, Optolong L-Ultimate narrowband (3nm, Ha, Oiii) filter on a ZWO AM5 mount with ASIAIr Plus. Total of 3h35m integration time.
