Description

Here is a pretty planetary nebula with a clunky common name—the Spare Tire Nebula. This image was captured in Ha, OIII and SII. Ha and OIII both generated strong signals and the resulting image looks quite different from versions constructed from RGB. I used PixelMath to create a palette that is approximately “realistic.”

Tech Notes:
ASA Newtonian, 500 mm aperture, 1900mm focal length, F3.6
FLI Proline 16803, 9 mm pixel, 4096 X 4096
