Spare Tyre has a halo
20 hours of O3 is showing a couple of faint shells around IC5148, the Spare Tyre nebula. Martin Pugh did a nice image that shows the brighter plumes at top and bottom right but I've never seen the shells before. If I had time to capture 80 hours they'd probably be quite obvious
I'll give it a couple more nights and see what I can do...
Cheers,
Rick.

Thanks, Mike. I may need to do the Megadata Anonymous program if I can't stop soon

Yep, the MA program is looking increasingly likely. Well done.

Super work Rick. You are on a roll for displaying super faint stuff. That seems to be just a bit above camera noise.

Thanks, Gary & Greg. This is one of those times where you collect heaps of data and hope there will be a worthwhile image at the end of it!

Thanks, Rod. It's only small (about 2 arcmin across) and quite dim. It hasn't attracted much imaging attention, probably as a result!

Great work Rick!
Another challenging planetary, interesting to see the result.
Cheers,
Justin.

A fabulous result Rick, those shells are certainly new to me. Great work
Now I'm looking forward to that 80 hour version!

Too late
I have about 75 hours narrowband on NGC6164-6165 now. I'm at the point where it's going to take a lot more data to make a significant improvement so I'll be processing that one shortly...

Why stop at 80 hours? If you are that close, why not go for the ton?

The incremental improvement in SNR is getting pretty small when I add new data, Pete, so another 20 hours won't make a lot of difference. Time to move to a new target.
Thanks for the kind comment. Scope is a Ceravolo 300 Astrograph - a 12" corrected Dall Kirkham. It would really shine if I had good seeing!
Cheers,
Rick.

Ever considered moving it to a dark site? The sky at Coona is nice and dark.

Would love to one day when I have time to set up for fully automated operation.

really interesting discovery Rick. Seems like multiple shells around PNs are more common than previously thought?

Looks like someone beat me to it, Ray:

Despite not having 20" aperture I'll keep at it and see what I can do (assuming some assistance from the weather gods...)
Cheers,
Rick.
