Faint Christmas planetary Wray 17-1

Hi all
Sky was clear Christmas night so got out and found this "faint fuzzy" on Star Atlas pro charts, in Puppis. [IMG]http://www.iceinspace.com.au/forum/attachment.php?attachmentid=7715&st c=1
Wray 17-1
3 x 10 mins ISP 1600, 10 inch F5.6 scope, Baader UHCS and MPCC, EOS 300D, off axis hand guided.
Lots of noise was present do to the warmish night. I used IRIS to extract the RAW images and subtract darks and flat field. I used Photoshop to stack them, adjust levels colour balance etc, then finished it off with Noiseware. This gets rid of most of the noise and amp glow.

Thanks folks.
Star Atlas pro gives its magnitude as 13.5 in H beta.

Arr! Another star expelling its atmosphere? Well done. It's darn faint that's for sure.

Looking at centre of the image;

it looks like a rather large but faint greenish circumstellar disc. In the central region is the dark core of the nebula where a central star can be seen. I can also see the two aqua-colored brightenings in the nebula (almost north and south). Are these other stars? or do you think it is part of the nebula being illuminated or ionized? perhaps by the central star ?

Paul
PS. looks like weather will be good tonight!

Yes, Paul those bright points are part of the nebula, must be bright condensed parts of the shell. Heres a fully magnified view.
