Sa2-21, Planetary Nebula in Puppis

Hi all.
Decided to capture this one before it slid toward the western horizon. It looks like a ghost image of the bright star, (16 Pup).

8x10 mins ISO 400. LPS filter, MPCC coma corrector. Modded 350D. 10 inch f5.6, off axis hand guided as usual.

Full sized version here

As I started the 2nd last sub the seeing started to deteiorate. I started as soon as it was properly dark, and the guide star was nice and steady, but towards the end it got rather mushy. While packing up and taking the darks, a wind came up and the stars started twinkling like mad. Gee Im glad I got the imaging done in the best window of opportunity

The PN is Mag 14.7, so will be a nice visual challenge, but times running out this season. Anyone going to the SPSP may want to pencil it in for the big dobs there.

I love Planetaries, theres so many of them out there that have rarely been imaged in colour, and no 2 are exactly the same.
