NGC 6826 Blinking Planetary Nebula

Unread post by menardre »

The Moon rises after midnight so I decided to re-image the Blinking Planetary Nebula (NGC 6826). I imaged this a few years ago but was not satisfied with the result. NGC 6826 is in Cygnus, so it is high in the sky at 8PM when I started imaging. I was able to capture 150 frames (2 minute exposures, -10C, binned 2x2, gain 100). When the Moon rose it was bright but fairly distant from Cygnus. I shutdown around 2AM after taking flats.

NGC 6826 is small (only 0.2 light years in diameter), so the image attached is cropped. You can just barely make out the outer shell of gas. The central star is on O-type star.

I'd never even attempt something only 25 arc-seconds in size. Seeing is normally 3 or 4 arc-seconds.
