Ah...there you go. In the UV, there appears to be a discreet point source in the centre of the area. If it's a PN then that would be the white dwarf remnant. Being that bright in the UV would also mean it's a fairly young neb and therefore quite small. It's giving off most of it's light in the UV which means it's surface temp could be anywhere upto 250-300000K.

Might be interested in giving it a go at taking a picture.

Ron don't worry about people who split fine hairs. They're as bad as people who sit and pick at typos and incorrect gramma where it it is plainly obvious what is meant. They clearly have nothing better to do than try to prove their superior intellect. Your post read fine to everyone else...

There is no needless picking here.

If you quote someone, you should give proper attribution. It has absolutely nothing to do with proving intellect nor in picking on errors.

If this original "...post read fine to everyone else..." then there is a serious problem here. Sadly, the originator of this thread actually did not write the majority of the text in the original introduction to this thread.

As said in the ISS Term of Service.

"Do not post copyrighted material. If you are posting something that includes material or images from another source or website, credit the original source and include only an excerpt with a link to the original article."

Sorry. Ron excerpted the whole text!

It could be a new planetary nebula that has just brightened up.

Look forward to see some spectra, as you've also said earlier.

Intriguing. Absolutely, no doubt.

It doesnt appear in uranometria 2000.0.

Here we go…the mag 4 Brisbane skies really made me work extremely hard for this one!

Tak Mewlon 180 F12 with x0.8 Reducer/Flattener operating at F9.6
SBIG ST7 CCD camera.
10 exposures of 15 minutes each, total duration 2 ½ hours.

The cropped inset is an enlarged view of the PN.

Nice shot, Dennis

From Sean’s post above (msg #19), I used the colour data from SKY-MAP.org and combined it with my (grossly enlarged) luminance data.

Colour data obtained from http://server7.sky-map.org/?locale=EN
