Description

I went to Casitas de Gila, Gila, New Mexico in October for astrophotography under clear, dark skies. I was there for 12 days and there were a few nights of excellent transparency and seeing. However, high altitude smoke from the California wildfires made imaging a challenge for a few nights. The first deep sky object that I imaged was the Helix Nebula in the constellation Aquarius. This planetary nebula was captured with two narrowband filters, Hydrogen-alpha (Ha) and Oxygen-III (OIII) over three nights. This is a false color image that combines Ha in the red channel, and Ha and OIII in the green channel and OIII in the blue channel. The white dwarf can be seen in the center of the pupil of the eye. This image also reveals the outer “eyebrow” of expanding hydrogen gas.
