RCW44 Planetary Nebula

Hi Guys

Not oft imaged and a challenge to process. The image is heavily cropped, as its only 2.5' in diameter. A lot of hrs Ha and OIII exposure time, too many to mention


Big here.

Also known as VBRC2, Wray 17-31 and ESO 166-PN-21.
It is an evolved planetary nebula in the southern constellation of Vela, and about 3,900 light years distant. The bright portion of the nebula is circular and about 2.5' in diameter.
The central white dwarf DAO (hydrogen/helium-rich displaying Helium ionisation) star is one of the hottest and most evolved known for a planetary nebula.

Taken on my RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
Processed with CCDstack, Star Tools and Photoshop.
Mapped as Ha Ha, OIII.
