captured the Eye (Blue Mountains)

For fun, tried to image the Cat's Eye planetary nebula.

With the intervalometer, shot 20 second subframes with a 1 minute gap between. Used a 10 second delay at the start. Manually focused. Shot 20 light frames.

It was bright blue! Wow. Could see some structure within. Like overlapping opposed ovals.

Canon 40D, Celestron 14", f/11, unguided, 20 seconds, 1000 ISO, daylight white balance, raw format. No processing (yet). North is bottom-right; east is top-right.


Tried stacking.
