Planetary Neb in M46 NGC2438 - HiRes.

SPX350 with 2xPowermate F9.1, Mintron12V6 (GStar-Ex), Astrodon filters.

Quite a faint and large planetary always wanted to see close-in as wide M46 images don't show it very well. At mag 10.8 and about 80% the size of M57 at 80" wide it shows as a beautiful ring with delicate red and blue colours. It is unrelated to M46 and much closer.

In the video at 2.56sec exposure the nebula looked extremely faint but stacking so many really brought it out strongly. Stacking so many has created a very smooth and detailed image probably my best with this uncooled 8bit video camera.

LRGB.
L=1400x2.56sec exposures.
RGB=700x2.56sec exposures each channel.

Thanks, John.
