MWP1, the Methuselah nebula, is an ancient planetary nebula surrounded by faint Ha and OIII nebulosity.  Another small, faint planetary nebula can be see to the upper left of MWP1, called ALV1 (Alves 1) which was only discovered 10 years ago by amateur Felipe Alves.

 

I believe this image is my longest exposure single image at over 65hrs of total exposure, about half of which is just OIII.  This is an HaOIIIRGB composition.

Very interesting. Is the surrounding gas emitting in OIII line somehow related to the nebula?

Good question. I really don't know but I doubt they are related.

Hi Joel

 

The image looks quite nice and the long exposure time was really worth it!

Thanks all!  It was a long project but I needed all that OIII and Ha to make it presentable.  What this object really needs is a fast 10" newt.
