Starless NGC6302 Bug neb-close up
Hi Guys
I had another poke at the Bug Neb in reverse Hubble pallet NB.
Starless, because of my fanatical persuit of a natural rendition
.
Lets face it, if you were this close up, you wouldnt see any forground stars, so why include them, he
, they are soo artifical, unecessary and messy
.
Ha:Ha:OII:SII Mapped as LRGB all 4 hrs each 10 min subs bin1.
Off axis guided with an SBIG AO8 (adaptive optics guider) operating at 2 hz
Taken on a 10"RCOS RC at f9 (2275mm FL), PME mount and ST10XME in urban skies
Also
here on my site.
Hope you like fuzzy closeups
.

Thanks guys. Yes, its a very violent, the center stars temp is 400,000 deg F making it the hottest known star in our galaxy, and particles are being ejected at 2 million miles an hr, which is colliding with earlier slower moving ejected gas heating the gas to 36,000, unusually hot for a planetary neb.
The "butterfly" stretches for more than two light-years, which is about half the distance from the Sun to the nearest star, Alpha Centauri .

Hi Fred, that's a very nice detailed image, that inspires me to try.
All the best.

I agree Fred foreground stars at this image scale are a distraction. With no stars I could not use Registar to put your image on one of my wide fields. So I used PS instead along with the eyeometer. Gives a much better idea of Fred's image scale and the fine detail he has captured.

Lovely detail. Bert

Thanks Lester, yes try it, its mag 13, but bright enough for 10min Ha subs at bin1.
Nice work Bert, thanks for the effort. I had no idea where it was in the sky like that, in a wide field shot, interesting.
Finding it took a while, a bit like playing wheres wally ;-).
Its 48 arc secs in size, a bit bigger than other planetary nebs ive imaged.

With stars, without stars, I like it both ways.
That image is a stunner!

Thanks again guys. I still have problems with stars, hence the lack of them. I dont mind them being there or not really. Im now thinking its the settings I use in fits liberator, stars are always saturated on import useing the log stretch, but using linear, or setting white level very high, usually needs far too much curving in PS. I can use seperate less-stretched layers for stars only, but its a long convoluted process. And in this pics case the core was blown too.
Id be interested to hear how others set fits liberator up for import to PS.

What a stunner of a pic.
Looks like a Saturn V ejecting its 2nd stage in some ways.

A fantastic image Fred, you really get a sense of the violence within the explosion that you described.
top stuff.
